WSUS Client won't connect after messing with proxy settings

[cookie_monster]

I was playing with the Windows Live installer the other day and noticed that it wouldn't work on our site, after some poking around i discovered that it doesn't work well from behind a proxy and it doesn't use the IE proxy settings.

 

I used the proxycfg.exe tool to set the WinHTTP service proxy and off it went, brilliant, or so i thought. The problem is that my WSUS server hasn't seen my box since. I used the proxycfg.exe tool to set the proxy back to blank as it was before but when i analyze network traffic with Wireshark i can see the WSUS client still seems to be asking the EMBC proxy where our WSUS is.

 

I've deleted all of the WSUS settings i can find but it's still not working.

 

Teach me to fiddle :-)

 

Any ideas?

 

Cheers.

Ah sorted it there was still a key set in the registry even though the proxycfg.exe tool was showing blank

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections
