Having a problem with Group Policy on some of our curriculum machines at the moment.
When anyone logs on (administrator/teacher/student) the User side of Group Policy seems to fail.
It doesn't seem to be happening to all machines or a specific set of users.
When logging onto an affected machine it takes around 10 minutes to complete the log on (usually about 20seconds), and the user will have no proxy settings or restrictions.
Group Policy preferences seem to be applying as they were getting network drives.
The client log files don't seem particularly helpful, in Application I get:
The winlogon notification subscriber <GPClient> took 481 second(s) to handle the notification event (Logon).
When digging down into the GroupPolicy Operational log I get a few more errors:
The LDAP call to connect and bind to Active Directory completed.
The call failed after 240148 milliseconds.
Group Policy failed to discover the Domain Controller details in 481388 milliseconds.
Error: Failed to register for connectivity notification. Error code 0x4CE.
I'm having trouble finding anything specific regarding these errors, hoping someone else here has a bit more experience and might be able to help me!
If anyone needs any more info or anything else I shall be watching this thread.
Edit: When running gpresult on a machine it gives "The user %User% does not have RSOP data"
