APPLIES TO
- Microsoft Windows 2000 Server
- Microsoft Windows 2000 Advanced Server
SYMPTOMS
When Microsoft Windows Server 2000 domain users try to log on to the domain controller, one of the following conditions may occur:
- The logon process takes a long time.
- The logon process does not succeed.
When you examine the Lsass.exe process on the Processes tab in Task Manager on your domain controller, you notice that the Lsass.exe process is using between 50 percent and 100 percent of the processor resources.
CAUSE
This problem may occur if the following conditions are both true:
- Many users try to log on to your Windows 2000 domain controller at the same time.
- The users who try to log on to your Windows 2000 domain controller are members of many groups.
The logon process builds and then sorts a list of the groups that a user is a member of. If the user belongs to many groups, the logon process may take a long time to build and then sort the groups list. If many users who belong to many groups log on at the same time, the Lsass.exe process may use more processor resources than expected. The logon process may not succeed because the domain controller is busy processing Lsass.exe.
