Unable to connect to Visual Studio’s Localhost Web Server


Screwing up an installation is so easy! I realized it when I was working on an issue today and had to uninstall the .NET Framework (that’s different story ;o). I used my Control Panel and uninstalled it, but I was not done yet! I wanted to wipe out all traces of .NET 2.0 from my box and I deleted the C:\WINNT\Microsoft.NET\Framework\v2.0.50727 folder. Then I simply re-installed it and found that everything was working fine except the projects which were being accessed through FileSystem. I was not able to debug those projects at all… Even a CTRL+F5 wouldn’t work!!


Here is the error message which I got…


—————————
Microsoft Visual Studio
—————————
Unable to connect to Visual Studio’s Localhost Web Server
—————————
OK  
—————————


Very soon, I found that there is a file called WebDev.WebServer.exe which was located in C:\WINNT\Microsoft.NET\Framework\v2.0.50727 folder and it was gone since I deleted the folder itself! Aahh… too late… But I was really happy when I found that when I copied the file WebDev.WebServer.exe from one of my colleague’s box, it worked absolutely fine :o) And that just saved me a lot of time!


I would have hated myself, if I had to re-install the VS 2005 just because of a simple mistake.


The point to be noted here are…
1) Don’t use Shift+Del to delete important folders. It is better to rename it ;o) (as if you didn’t know already!)
2) In case you do the same mistake as I did… find a person who has the file, and Copy + Paste!!
3) It seems like VS2005 installation puts the file (WebDev.WebServer.exe) in the Framework folder. Take good care of it :o)


Cheers,
Rahul

    actually i have the same problem and that exe file also exists in that directory

    give me a suggestions

  2. rahulso says:

    How did you get the problem?

    Was it working earlier? Do you remember any change which was made in this box after it stopped working?

    You may also try using Filemon to see if there is any Access Denied or some file being asked for and not present in the system. May be that will help.

  3. Frank says:

    Thanks for the tip.

    I had the same problem yesterday. I was too fast deleting the v2.0…. folder. Now after i copied the webdev.webserver from my second machine all is working fine again.

    Cheers, Frank.

    Thanks for the tip about the missing exe.  

  5. prakash says:

    Hi i am also facing same problem "Unable to connect to Visual Studio’s Localhost Web Server", i have that "WebDev.WebServer.exe" file in my "C:WINNTMicrosoft.NETFrameworkv2.0.50727" folder.

    I am not able to detect exact cause to this problem.

    I am not able to debug any web application.

    Event Ctrl+F5 is also giving same error…

    So, i get two error messages as below :

    1. "Unable to find version of the runtime to run this application"

    2. "Unable to connect to Visual Studio’s Localhost Web Server"

    Please help me out…

  6. Hi Prakash,

    Check if you are able to create a new Project. Also, find out if creating a project with FileSystem works or not. If filesystem works, your debugger is fine. Then check out what version is listed under the ASP.NET tab in your IIS server.

    Also, try using aspnet_regiis -ua followed with a aspnet_regiis -i and see if that helps.

    If you still have problems… Let me know the following…

    1. Does creating a new Project work?

    2. What is the Operating System and VS you are working on?

    3. When did this problem start?

    4. Has it ever worked correctly on this box?

    5. What happens when you try to debug against a File System project. Give me the exact error message which is thrown.

    6. What version is set for the project in IIS under that ASP.NET tab?

  10. Hi Megha,

    It this happens daily, I have a feeling that there is something goofy going on from the Policy perspective.

    Give me the exact error message which you are facing. If it is the same error message as this post, try removing your PC from the domain and re-install. Let it be out of domain and try to repro the issue and see if that happens again.

    thannks

  15. Hi Raghu,

    Can you give me the following information…

    1. Your OS

    2. Are you an Admin on your box?

    3. Is this PC part of a Domain or WorkGroup?

    4. Where are you located?

    5. Do you have IIS installed on your box? If yes, did you try creating a new project on your http://localhost/AppName??

    Regards,

    Rahul

  16. Raghu vamshi says:

    Hi Rahul

    My OS is Windows XP SP2

    I am Admin on my box

    My pc is part of Domain(Stand alone)

    IIS is installed in my system.I have created a new project and began to run ,when trying execute from the internet explorer (http://localhost/….)    an error occured stating that it is wrong to use authinication mode  Windows in the web.config file

    so what could be wrong i do not understand

  17. Hi Raghu,

    It seems like you are not using Integrated Windows Authentication Mode in IIS.

    Can you please try that and let me know?

    Also, it would be really nice if you could give me the EXACT error message. Press CTRL + C on the message box which is thrown for the error and paste it.

    Regards,

    Thanks so much for posting this!

    I deleted the .NET2.0 folder earlier today to test a setup program’s installer of the .Net framework. And after it installed I couldn’t build my websolution anymore. Turns out I deleted this file! Thanks for the solution!

  19. Ed Winborne says:

    I get the same error message when I try to use the website menu->ASP.NET Configuration in the Visual Web Developer 2005 express edition to load the Web Site Administration Tool. I also get this if I right click on the open window and click "View in Browser". In All instances I get a local host Icon on my task bar Labeled ASP.NET Development Server, and a path such as http://Localhost:1548/WebSite2, which is the path to my website created by Web developer. If you right click on the Icon you get a dialog box with the following options "Run in browser", "Stop", and "Show Details". If you Click option 1 or 3 you get the above Error message "Unable to connect to Visual Studio’s Local Host web server" but for option 1 the Internet Browser loads with a list of the files in the project which you can run to see if they will run in the browser for debugging. Option 3 does esentially the same thing but gives details about the physical path, the virtual path, Port Number, and the root URL which is a link you click on to do the same as option 1. With all these options I get the same error message as above every time I click any of the above options. Also I can not get the Web Administration tool to load and run no matter what I do. I have checked and all of the files and directories mentioned above are present in the right folders. I Have IIS installed on my computer and have tried loading and running the web administration tool in Visual Web Developer with IIS enabled and disabled but it makes no differance. I can run and debug aspx files from my virtual IIS directory with out any problems. Can Any body tell me why I am getting this error message and how to get the Web administration tool to run?

    i work on file system not on iis ,it was working fine

    suddenly it started throwing this alert message–"unable to connect to visualstudios’s localhost web server"

  21. Peter says:

    Same thing here. Windows XP Pro SP2 / Administrator, standalone. I created a new website in VWD2005 Express Edition, localhost/appname. When I go to Website-ASP.NET configuration it starts the ASP.NET Development server and in a while it throws "unable to connect to visualstudios’s localhost web server:. I reinstalled .NET 2.0 and VWD2005 EE and it seemed to work fine. After an hour or so, same problem! I also did the aspnet_regiis thing as mentioned above. Help….

  22. Peter says:

    Sometimes, not always(!), I can start Menu-Website-ASP.NET Configuration AFTER I did a Menu-Build-Rebuild Website. Other times it gives me the error "unable to connect……" It also seems to depend on the portnumber that the localhost web server is openening. Windows Firewall is off. Can I shut down this webserver and always use IIS instead?

  23. Peter says:

    It gets even stranger…. I had two instances of SQLEXPRESS on my machine and I disabled the second one (SQLEXPRESS with FULLTEXTSEARCH enabled). Now my VWD is working fine! I can acces the ASP.NET configuration and I can use Visual Studio’s localhost web server. I let you know if there are more problems from now on.

  24. Sandip says:

    dude, i did something similar to what u did..i uninstalled VS2005 first without uninstalling the patch for WebApps.and then coz i cant uninstall the patch..i just tried to get stuff done by installing VS2005…ignoring the patch alltogether!one look at ur blog and i knew where i screwed up!!thanks a million dude!!

  25. Ganga says:

    hi,

    i am getting two errors like-

    1.ASP.Net development server failed to start listening on port 1290.only one usage of each socket address is normally permitted

    2.unable to connect to visual studio’s localhost web server

    i have installed VS2005 and i was working comfortably fine with the application yeasterday but today its showing me the above errors.i have that "WebDev.WebServer.exe" file in my "C:WINNTMicrosoft.NETFrameworkv2.0.50727" folder.

  26. Hi Ganga,

    Honestly speaking, I haven’t seen this error before. Can you kill all instances of your webdev.webserver.exe and try again?

    Also, if that doesn’t work, try reproducing the error and run netstat -ano from your command prompt. It will tell you the PID of the application who is using the port which is conflicting.

    In my case, when I was browsing a file the URL looks like the following….

    http://localhost:1042/myProject/Default.aspx

    And when I do netstat -ano, I get something like the following…

     TCP    127.0.0.1:1042         0.0.0.0:0              LISTENING       2656

    Here 1042, is the port number and 2656 is the PID of the process. You can have a look at this PID in Task Manager (View – Select Columns – PID) and figure out which app is causing the issue.

    Hope that helps,

  27. Dabbler says:

    I don’t seem to have the WebDev.WebServer.exe in my C:WindowsMicrosoft.NETFrameworkv2.0.50727 folder. I seem to remember reinstalling .NET framework a while ago, and just tried to use ASP.NET Configuration from the Website menu… am getting the same "Unable to connect to Visual Studio’s Localhost Web Server" error. No sure what I need to install, uninstall. Is there some way I can extract this file without uninstalling and re-installing?

    Thanks!

  28. Hi Dabbler,

    Do you have any other box which has VS 2005 installed? If yes, you can probably get it from there and retry!

    You may also try using the extract command… http://support.microsoft.com/kb/129605. I haven’t tried it on VS installs, but I guess it should work.

    I have an ISO file with me to install VS 2005. It helps me in doing such stuff.

    Hope that helps,

  34. Hi Michael,

    Are you logged on as an Administrator? Do as follows…

    1. Login as Admin

    2. Create a very simple text file and call it test.aspx. Check if you are able to run that page on that IIS.

    3. It seems like the IIS is not appearing healthy or it could be something related with permissions.

    4. Also check if you are able to browse any htm or asp pages.

    Hi, Rahul

    When I open in VWD 2005 a localhost website ("http://localhost/mysite") and press F5, it runs good.

    But when I open site in file system("C:/mysite) and press F5 or Ctrl/F5 it gives the message ("unable to connect…")

    Michael

  36. nifigasebe says:

    when I create new site in LOCAL IIS mode it works fine. when I create even very simple page in file system (C:/WebSites/simple.htm) it is unable to connect …

    I reloaded VWD 2005 Express Edition, made sure WebDev.WebServer exist, but nothing changed. I guess my ASP.NET is not installed properly.

    I tried to correct it but failed.

    Michael

  37. nifigasebe says:

    Maybe I need to correct my .NET Framework, and then reinstall ASP.NET?

    Michael

  38. Hi Mike,

    Have you tried creating a new project in some other folder, like C:TestFolderTestWebSite? If not, please try that.

    If you like you can install Process Monitor and check if you are seeing any access denied on the folder where you are creating the website.

    Re-installing .NET Framework might help as well in your case.

    Everything was working fine. Then, i made some changes in date to do some experiments. first i forwarded the date by few months. Then, put it back to current. In the meanwhile, it started giving these errors:

    – asp.net development server failed to start listening on port 1038 an attempt was made to access a socket in a way forbidden by its access permissions

    – unable to connect to visual studio localhost web server

    I have verified the existence of file WebDev.WebServer.EXE at this path: C:WINDOWSMicrosoft.NETFrameworkv2.0.50727

    its there.

    can anyone give me some idea?

  40. Hello Horizon,

    Do you have any Antivirus/Firewall which is locking up the port?

    By any chance, are you using source safe?

  41. Alex says:

    rahulso’s brilliant suggestion of checking the pID in netstat and killing the process in the Task Manager solved my problem. It was a process called ‘SR_Service.exe’ which is to do with my VPN client.

    Thanks Rahul 🙂

    pls help me.

  44. Hi Sasi,

    This error message typically means a serious failure of the network system (i.e. the protocol stack that the WinSock DLL runs over), the network interface, or the local network itself is broken.

    2 things…

    1. Do you get this error message with the same port number everytime?

    2. Do you have any proxies and is ByPass Proxy server for local addresses checked in your IE??

  45. sasi says:

    i,

    thanks for ur reply, actually i am doing at home computer caught this problem

    is there any solution , i have to format the computer ,reinstall everything

  46. Gourav says:

    open Internet option.

    select connection tab then open lan setting.

    There select bypass proxy server for local address.

    i will work.

    Hi every body I want to till you that I was have this problem and I try alot of solutions to solve it but without any benefits but I found that the reason of this problem is this file that called WebDev.WebServer

    hi all,

    this is  Dilip,i am facing a huge problem, i did everything but it is still there.

    My problem is

    At the time of Debug for Windows application it gives error as "the application failed to initialize properly (0xc000007b)" and

    for Web application it gives error as "unable to connect to visual studio’s localhost web server"

    Due to this i can not work on either Web  or Windows application at all.

    I read several solution but all just hit and try methods but it won’t help me. All say they just solved their problem by some luck but no one got exact solution.

    I reinstalled VS 2005 and Win -XP both doesn’t help and also format my machine then install fresh copy of both.

    Also Reset IIS and install framework 2.0 but it won’t help me.Even i don’t have any firewall installed but same problem persist.

    I also copy WebDev.WebServer.exe from my friends machine to my machine but no luck.

    Please give some genuine solution, not just hit and try solutions.

    I can not work on any type of application.

    If this problem persist that means Microsoft VS 2005 and XP has some serious bug inside.

    Please …….Provide  me solution.

    Thanks & Regards

    hi all,

    it’s me dilip again, butstill no solution. i think the problem has difficult solution.

    That’s why no one is interested in giving appropraite solution.

    Thanks & Regards

    Dilipv

  53. Hi Dilip,

    Your problem looks a bit tricky. Typically, the error message 0xc000007b would mean…

    # for hex 0xc000007b / decimal -1073741701 :

     STATUS_INVALID_IMAGE_FORMAT                                   ntstatus.h

    # {Bad Image}

    # The application or DLL %hs is not a valid Windows image.

    # Please check this against your installation diskette.

    # 1 matches found for "0xc000007b"

    Thus, it appears that the file is corrupt. And I believe that it is not a bug. Tell me the following…

    1. Try installing VS from any other source. If you can do it, try installing Visual Express and see if that works for you (it is free).

    2. Are you able to create new projects and debug them properly?

    3. Did this ever work on your machine?

    You may also try to open a case with GTSC-India and they should be able to help you out on this issue.

  64. Hello Sujna,

    It appears that the port is blocked. Do you have a firewall?

  65. sujna says:

    I suffered the same issue "Unable to connect to Visual Studio’s Localhost Web Server", and I have resolved it now.

    It was due to a FIREWALL program installed on my PC.

    so please make sure to uninstall or close any such program if running.

    Regards!!!

    Ok  another fix to try….

    After you have verified that you have the WebDev.WebServer.EXE file and can double click it and it returns with help information.

    Take a look at your hosts file in the folder…

    C:Windowssystem32driversetc

    Open Hosts and ensure you have an entry such as the following…

    127.0.0.1       localhost

    For some reason mine was garbled and I hadn’t even touched it.

    hi Rahul,

    I am getting error 404.4. It says  "The resource you are looking for does not have a handler associated with it."

    In the "things you can try,  it states,

    "If the file extension does not have a handler associated with it, add a handler mapping for the extension."

    However, it doesn’t explain how to do this.

    Config of System:

    OS: Windows Vista Home Edition.

    Browser: IE 7.0

    The system has Visual Studio 2008 installed on it. So the application runs on local host.

    But it does not have an IIS server installed.

    This error cropped up after I tried to run Spike Proxy (Web Application Security Testing tool) on my system, for which I had to change my browser settings. But after using it I changed the settings back to wht they were.

    But I am still getting the error.

    Please help me with this…..

    Thanks
