if group policies are ignored, but all other policies work as expected:

1.Grouppol.dll is not in the \WINDOWS\SYSTEM directory.

2. The group in question is not a Global Group. (or group priority isn't set in correct order)

3. The policy file for a specific user exists which overwrites the group policy.

4. The registry has not been updated to include the grouppol.reg entries.

These entries can be added by "double-clicking" on the grouppol.reg file. If you don't have the grouppol.reg file, add them manually on the client:

- Registry key: HKEY_LOCAL_MACHINE\Network\Logon
Value name (STRING): PolicyHandler
Value data: GROUPPOL.DLL, ProcessPolicies

- Registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSNP32\NetworkProvider
Value name (STRING): GroupFcn
Value data: GROUPPOL.DLL, NTGetUserGroups

- Registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NWNP32\NetworkProvider
Value name (STRING): GroupFcn
Value data: GROUPPOL.DLL, NWGetUserGroups
