I have a domain with two dc's. I have been using RDC to access one from the other, that is until this morning. Now, I get the error msg that the target computer is not accessible because it is either 1) turned off or 2) RDC is turned off or 3) the computer is not on the network. None of this is true. The target machine IS on and logged in. RDC is turned on in Remote tab of Computer Properties. and the target machine and its shares are accessible. Furthermore, the target machine is able to browse the network and the internet. Could the updates have wrecked this setup? And if so, can I do a system restore to yesterday? There doesn't seem to be that option in All Programs->Accessories->System Tools. Please LMK how to fix this annoyance.
