Metaframe 1.8 nt4.0 server sp6a winlogon.exe help

[mcseken]

i have a server that is a older nt 4.0 sp6a box running metaframe 1.8. roughly 35 clients use citrix in a part PC and part Terminal enviroment.

the problem im having is when the terminals shut down at night. if 3 or more terminals shut down it locks the winlogon.exe service on the nt server at 99% and no one can use citrix till it releases.. after 5 minutes it lets go and everyone can log off or continue working. it only happens when the first 3 log off. if i log off 5 terminals at once it will lock things up for 10 minutes. the pc's you can shut all down at the same time and it doesnt lock the server. ive seen some articles with 2000 TS sp 4, but these dont seem to match.. im running the latest sp for terminal server and nt 4..

any help would be helpful..

thanks-

Ken

The best option would be to dump the winlogon process while it pegs the CPU to 99% using userdump and then analyse the process dump (Microsoft or Citrix can do this for you if you have a contract)
