Yeah, I'm still running 2003. In fact, I'm still asking the lab admins to build out new 2003 boxes. And when I log onto them, I get that next-to-useless "Manage Your Server" box.
Here's how to blow it away in a cmd.exe or PowerShell.exe window:
reg add "HKCU\Software\Microsoft\Windows NT\CurrentVersion\Setup\Welcome" /v srvWiz /t REG_DWORD /d 0 /f
Unfortunately, HKCU is instantiated only when I log on, so I can't use the remote reg hack to set it.
I could set it globally on the machine:
but that would constitute a config change and I'd have to justify it to the Powers that Be. (That's why I didn't ask for it to be set either in the image or as a GPO.)
Looks like I'll have to resort psexec.exe \\$myComputer -u $env:userDomain\$env:userName
