RDP not working after Sept. patching

[SG_Dan]

I have a series of windows 2003 SP2 servers in a small domain, 3 are real
hardware, and 3 on MS virtual server. During and after applying the latest
patches to all of these servers, I'm noticing that in all cases I can no
longer access my hardware based servers using RDP, or even Remote desktops.
The error I receive on RDP is simply that "This computer can't connect to the
remote computer." My primary workstation is Vista, but I get the same error
running from a fully patched XP workstation as well, both are joined to the
same domain. Has anyone else seen this behavior and hopefully found a
resolution?

Additionally I find in the Vista system log the following DCOM error which
shows a number of remote issues similar to this one:

Have you tried removing the most recent patches from one of the
servers?

Maybe you could find out which patch caused the issue.

Re: RDP not working after Sept. patching

Thanks moncho, I decided to try your suggestion, and choose my DC to try the
uninstall, but first I wanted to review event logs to be sure, and once I
logged in locally on the server it reported it was shutting down. I was
surprised by this and logged into another server, and the same thing
happened. In both cases when I was able to log in, I saw the familiar green
shield on the system try telling me my server had restarted after a patch
update. I completed this process on all my servers (hardware based only) and
they have all come back the exact same way. I then opened RDP sessions on
them all to confirm, and they too were successful. I can only conclude that
some how, this patch cycle didn’t complete the restart cycle (even though
each did reboot after patching) and were all in a “needing restart” state,
which of course will inhibit RDP connections. Additionally all the
applications were fully responsive, including my Exchange server! This is
just weird, but I’ll continue to trouble shoot.

So you are saying that the server immediately rebooted once you logged
into the console without any interaction by you?

That sounds weird. Let us know if you find out anything.
