I've found several posts/discussions on this topic but no real answers.
I thought that I'd post again just in case...
We recently upgraded to Xp SP3 and since then we seem to be having RD/TS connection stability problems.
We are running SBS2003 and XP Pro SP3 on all necessary machines and are experiencing disco's from multiple locations.
When Disconnected users recv a non specific error (no message, just disco)
Error logs are not showing any signifigant events (or I am not looking for the right thing)
We have verified licensing (all is good) and settings in TS/Users accounts.
We have double checked firewall and other various security settings and don't see anything unusual.
We have also made sure that we have cleared "hung" sessions.
Sometimes the users can reco, other times they cannot...

How long has the server been up? I would try a reboot, at night and see if this fixes the problems...

I hadn't thought about that but we did just update and reboot the servers about a week ago. We had the problem prior to and after the reboot though.
I also looked through the TS/RDC configuration yesterday to ensure that it was correct, everything still looks OK, but I did notice that Server is v5.2, and all of my clients (under xpsp3) are v6. I have not yet noticed any posts to that specific issue but any thoughts are appreciated.

Tuff issue... What kind of networking equipment do you have in place? If the event log isn't showing anything, and everything appears to be fine. I would start to look at the routers and switches, a device might be broadcasting gibberish. in-turn sucks up all the bandwidth, causes the disconnect... Im just kinda shooting in the dark... You have covered everything in the server that I would have looked at. I am suggesting network, cause I recently had found out what was causing my network to be at a crawl... My main router was shot! We weren't getting disconnects but might as well have....

Edited: 2nd thought, the equipment might not be forwarding the packets correctly. And the requests might not be even hitting the servers...?

I like the idea you present here. I have suspected a broadcast storm of some kind and the packet forwarding issue. What is throwing me is that I cannot isolate it to local LAN or ISP based. I have evidence pointing strongly to both.
The ISp recently did some upgrades that caused us to lose our Static IP and it has just never been the same since.
I am leaning toward it being a two (or more)part issue that just happened to occur at the same time.

I apoligize I negelected to mention that Server has SP2 already.
I also have thoughts (concerns) that the Terminal Server is v5.2 and RDC is 6.0 under XP Sp3.

BTW - I'd like to thank everyone who has contributed to this issue and (hopefully) its resolution.
I am really out of ideas on this and appreciate the input!!

I've reverted one of the affected machines to Xp SP2.
The issue no longer is occuring per users reports.
However I cannot say I am convinced that this fix resolved the issue.
1 PC at 1 location (out of 5 pc's at 2 locations) rolled back to SP2. All others still have SP3...
Perhaps I missed a Windows update or ISP fixed an issue...
Thanks again to all who helped. I'll repost if issue reoccurs, but it appears resolved for the moment.

This issue seems to be connected with using a DNS name; try using an IP address as we have not experienced disconnects with the IPs, but we do with DNS names.
