Cause for Remote Desktop Connection Failure?

I have encountered the following problem with a Vista x64 machine. Connecting to the machine via Remote Desktop just stopped working (probably after a windows update) – was working one day, not the next. On investigation found:

• Services manager reports Terminal Services service as Automatic and Started
• netstat –a –n shows port 3389 not open -Event log shows the error “Terminal Service start failed. The relevant status code was No such interface supported”

Best suggest fix I can find is to add the Network Services account to the administrator group:

net localgroup "Administrators" "NT Authority\Network Service" /add

This works, but can’t be very secure and I’d like to find a proper explanation and fix.

• In my research for this question it looks like everything has to do with the Network Service Account suddenly not having enough permissions to access the network or becoming corrupt in someway.

  Maybe you can try This link which will reset your VISTA security settings.

  You can also try restoring an old registry copy if you have one, you would need to boot into the recovery console to replace the files in c:\windows\system32\config
