remote user can't log on anymore

[crabby117]

I have a remote user who used to be able to log into our Terminal Services server (2k3) with his windows XP PC. He emailed me stating that he's no longer able to do it since he's gotten a new Vista PC (not an upgrade to the old PC).

I used his login info and was able to log on as him just fine with my own XP PC. I had a colleague use this user's login info with a Vista PC and he was able to log on just fine as well. I have made absolutely no changes to the server, so I'm not sure why this user can no longer log in.

He says that he gets the login prompt, but then gets his connection bumped immediately. The Event Viewer on the server acknowledges that it got his login info.

I'm at a loss as to why he's not connecting beyond the longin prompt. Any ideas? Thanks much in advance.

On his Vista machine, have him click on the "Options" button on the RDP client. Then click on the "Advanced" tab. There is a section there for "Server Authentication". There are three options:

1) Always Connect, even if authentication fails
2) Warn me if authentication fails
3) Do not connect if authentication fails.

I would wager that he has number 3 selected. If he changes it to 1 or 2, he should be good to go.

Thanks FloDiggs. I've have the user try it, and I'll post the results.

The user reported that the authentication setting did not remedy his situation. He still cannot log on.

I was considering deleting his profile and login account, recreating a new account, and letting a new profile generate. I'm not sure that'll work, but it's worth a try.

So he get's the first prompt for user name and password does he get the second one. This one says something like. Remote Desktop cannot verify the identity of the computer yada yada yada... If not then he may have a corrupt application (the rdp app). Try logging in as you from his PC via rdp. Does that work? If so then delete his vista profile should be fine.
