SMS: Program Group Control May Cause an Access Violation

Under certain conditions, an access violation (AV) may occur when Program Group Control (PGC) first runs after you log on to the network. Under Windows 95, this problem manifests itself as an AV in Kernel32.dll. Windows 16-bit and Windows NT platforms can also be affected.


As PGC starts, it enumerates the user groups to which the user belongs (global groups for Windows NT domains, or user groups for NetWare domains), for the user's current logon domain, and for each server listed in the user's Sms.ini file.

If the user is a member of a substantial number of user groups and also has two or more logon server entries listed in the Sms.ini file, this problem may become evident during every logon attempt.


Microsoft has confirmed this to be a problem in Systems Management Server version 1.2. A supported fix is now available, but has not been fully regression- tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
