hi. somehow we already manage to found out the solution.
Problem:
When installing for client using each region PGP-Client (eg: Northern PGP-Client), some user will have the error where the group policy is different with the server. When viewing the logs, is shows that the client policy is different from the server. Thus, the PGP unable to start at all.
Solution:
When login to the PGP Server, under consumer and find the particular username with problem, notice that he/she was not added to the WDE-(Region) policy. By manually add he/she into the group policy/group region, and reinstall the client, the PGP able to start.
Findings:
This only occur to certain users where the PGP-Server does not synchronize with the Domain Server. This might be the issue of the time delay between the two servers retrieving the information.
It look like maybe there is problem on synchronization as it usually occur to new user.
