"No such interface supported" error on IISRESET

Today, one of my customer came up with an error message. He was getting "No such interface supported" when he did an IISRESET. I was not able to reproduce his issue on our box here.


No such interface supported

I was getting puzzled on seeing this error and did a search on the internet, but didn't get any useful links. Some tried to do a reinstall of IIS. When I was looking through the dlls in system32 folder with regards to IIS, there is a file called iisrstap.dll. I tried to unregister this dll.

C:\WINNT\system32>regsvr32 /u iisrstap.dll

Then, tried an IISRESET command.


No such interface supported

Great!!!!! I got the same error! Advised one of my friend who is working with that customer now to try the same. Not sure whether this will fix his issue. But I am sure that this will help someone facing this kinda problem. You can try re-registering the iisrstap.dll to fix this problem.

C:\WINNT\system32> regsvr32 iisrstap.dll

    had this problem, when running "regsvr32 iisrstap.dll" i got an error. i copied this dll from another system, ran the regsvr32 and it resolved the problem.
