Question : Group Policy Not Being Picked Up?

User Policy update succeeds.  

Error reads:

User Policy update has completed successfully.
Computer policy could not be updated successfully. The following errors were encountered:

The processing of Group Policy failed because of lack of network connectivity to a domain controller. This may be a tran
sient condition. A success message would be generated once the machine gets connected to the domain controller and Group
 Policy has succesfully processed. If you do not see a success message for several hours, then contact your administrator.

To diagnose the failure, review the event log or run GPRESULT /H GPReport.html from the command line to access informati
on about Group Policy results.

This persists however.

GPReport reads:

Group Policy Infrastructure failed due to the error listed below.

The network is not present or not started.

Note: Due to the GP Core failure, none of the other Group Policy components processed their policy. Consequently, status information for the other components is not available.

Additional information may have been logged. Review the Policy Events tab in the console or the application event log for events between 12/29/2009 3:12:08 AM and 12/29/2009 3:12:09 AM.

DNS/etc. is good.. ICMP success, lookups no problem, etc.  No idea what the problem is at this point.

Answer : Group Policy Not Being Picked Up?

You could try a few things.
Remove the PC from the domain. Delete it on Active Directory.
Then re add the PC to the domain.
Then try a GPupdate /force
then check by using the gpresult.

If this doesn't work try clearing the PC's GP entries back to default.
Use the following in a .BAT file

secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose

This will clear out anything that maybe stopping new policies from being applied.

Something else you can check is that the GPO's are enabled and linked in GPMC.

Get back to me if none of this fixes it.
