When you run the GPResult.exe (Group Policy Results) tool on a Windows Server 2003 PDC emulator, you may receive:

Account Policies                              ----------------                                 GPO: Default Domain Policy                                 Policy:            MaxServiceAge                                 Computer Setting:  600                                 GPO: Default Domain Policy                                 Policy:            MaxTicketAge                                 Computer Setting:  10                                 GPO: Default Domain Policy                                 Policy:            MinimumPasswordAge                                 Computer Setting:  N/A                                 GPO: Default Domain Policy                                 Policy:            PasswordHistorySize                                 Computer Setting:  3                                 GPO: Default Domain Policy                                 Policy:            MaxClockSkew                                 Computer Setting:  5                                 GPO: Default Domain Policy                                 Policy:            MinimumPasswordLength                                 Computer Setting:  N/A                                 GPO: Default Domain Policy                                 Policy:            LockoutBadCount                                 Computer Setting:  N/A                                 GPO: Default Domain Policy                                 Policy:            MaximumPasswordAge                                 Computer Setting:  43                                 GPO: Default Domain Policy                                 Policy:            MaxRenewAge                                 Computer Setting:  7
When you run the GPResult.exe tool on a computer that is not the PDC emulator, you may receive:
Account Policies                              ----------------                              GPO: Default Domain Policy                              Policy:            MaxServiceAge                              Computer Setting:  600                              GPO: Default Domain Policy                              Policy:            MaxTicketAge                              Computer Setting:  10                              GPO: Default Domain Policy                              Policy:            MaxClockSkew                              Computer Setting:  5                              GPO: Default Domain Policy                              Policy:            MaxRenewAge                              Computer Setting:  7
This behavior will occur when you run the GPResult.exe tool on a computer that is not the PDC emulator.

Some policies are designed to be automatically replicated by Active Directory, and are NOT reported on replicas.
