PC slow when connecting to it via RDP
I have a PC that is Windows XP Pro SP3 w/all updates installed and 2Gb of RAM. When you log onto the workstion locally, there are no issues with the computer. However, when I connect to this PC via Remote Desktop, the computer is very slow. I have run Process Explorer and one of the csrss.exe processes is taking up alot of CPU time.
I have dug in to the csrss.exe process with process explorer. When i look at the threads, I see that there are 2-3 threads that are taking all the time and each thread is the same. It is:
CSRSRV.dll!CsrValidateMess
I have also ran Registry Monitor and found that this process is pounding the following registry key: HKLM\SYSTEM\Setup\SystemSe
REGMON can sucsessfully read this entry. This entry is set to Hexadecimal value of "0".
I have tried reloading this computer and the issue is still there. This happens with any user that RDP's into this system, but does not happen when you log on locally. I have also tried dumping some of the profiles on the system and letting it create new ones and this is still an issue.
I have tried to get into the system using console mode with Remote Desktop (mstsc /Console), and this still doesn't work.
The only thing that does seem to fix the issue temporarily is when i kill all 2-3 threads that are taking up the CPU time in the CSRSS.exe process.
I am totally stumped at this point. Does anyone know how to fix this issue?
Thanks in advance!

We have had our network tested by our software vender within the last 4 months and they said our network was setup great. The computers we are having this issue on are used by employee's that work from home. They VPN into our network and then RDP into these workstations. If i remote into these workstations from inside the network we get this same issue. So i don't believe it is a network issue. We do not have any issues with any of our other 225 workstations. We do about 10 workstations that employees RDP into from home and they aren't having this issue. Now having said that, one of the workstations that we having the issue has been reloaded recently and this didn't seem to help. Also note that this model of workstation is used in many locations including a few employees that work from home.
Hopefully that all makes sence.
