Error message when you try to log on to a Windows Server 2000 - based terminal server

Last week, I installed and run spybot on a Windows 2000 terminal server, and also some windows updates (NB; For some reason or another, but not known to me, this server has never had any windows and antivirus updates for some time, and it was showing signs of infections), after a restart over the weekend due to the updates, Users this morning started reporting failure to log on to the terminal server with this error:

"Windows cannot log you because the profile cannot be loaded. Please contact your network Administrator (in this case me), insuficiet system resources exists to complete the requested service"

Now, I half expected this or atleast some problems to surface after the maintenance work I did on the server.

However, it did take me a good 30 minutes to sort this one out, microsoft knowledge base, suggested two things, first increasing the maximum registry value (Control Panel -> system -> advanced -> perfomance options -> Change

Secondly tweaking the registry.

1. click start -> run -> type regedit and hit Enter.
2. Locate and click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
3. On the Edit menu, point to New and then click DWORD value
4. In the New Value #1 box, type PoolUsageMaximum, and then pres ENTER.
5. Right-click PoolUsageMaximum, and then click Modify
   
6. In the value data box, type 60, click Decimal, and then click ok
7. if the PagedPoolSize registry entry exists, go to step 8. If the PagePoolSize registry entry does not exist, create it. ( Edit Menu -> New -> DWORD Value -> type PagedPoolSize in the New Value #1 box, and press Enter.)
8. Right-click PagedPoolSize, and thn click OK
9. Exit Registry Editor, and then restart the computer.

Everybody, is working fine now and the phones have gone queit
