I've got two clients using the RDP function in SBS 2003 RWW on a very regular basis. The logon is working OK at high resolution but when they return to the office their workstation (XP Sp2) ha reverted back to a 640 x 480 resolution. Only way back to normal resolution seems to be a restart. Any idea's anyone?
Regards
Olaf

Get the latest RDP client and try with it.

Also make sure you update the video drivers on these machines to the latest available.

Thanks Tsmvp but RDP client is already version 6 and latest VGA drivers. That was the first thing I tried.
Only started in the last week. RDP update was WSUS as soon as it came out and VGA drivers were updated two months ago and there are no updates.

On whose machine does the resolution go back to 640x480? On the rdp session or on the client's machines after they've logged out from the rdp session?
is it affecting just these two machines or other machines as well?

It's affecting two machines in one site and one machine in anotherso far.
It's affecting the target workstations. When they return from the outside world (hence the RDP) their workstations in the office are sitting at the: This machine has been locked... at 640x480 resolution.
When they logon it stays at 640x480 resolution till you change it manually or restart.

what changed?
have u tried msconfig to disable all the third party services and startup items?
tried reproducing the issue by logging into the client machine with a different user account and then doing an rdp?

No, this is based on client reports.
I have only seen it once myself. Eventlog was clean at the time and I just restarted to get the client going again.
I do know that except for Automatic Updates from WSUS nothing has changed.
I was just wondering if someone else has had similar issues.

Further update: Only happens if user is logged on at the local workstation at work and logs on remotely too.
Only fix is a restart of the workstation.

This is still happening. Only when same user logs on to his/hers open profile at work.
Happens on 3 of the 25 SBS I administer.
Any ideas anyone?

I think I have a possible answer: Only happens to users with a large amount of files or large files on the desktop.
If I clean the desktop it does not seem to happen.
Possible?

Thanks for helping out. I have now proven that big files on the desktop cause the problem but thanks for stearing me in the right direction and taking the time to help out.
