Group Policies not applying
Good Afternoon All,
I am troubleshooting (and raging at) an issue with group policies not being applied intermittently in our ICT Suites.
PC boots up and fails to perform an LDAP bind
Then applies no group policies to the PC
then applies no group policies to any user who logs in!
System - Event ID 1006 - "The processing of Group Policy failed. Windows could not authenticate to the Active Directory service on a domain controller. (LDAP Bind function call failed). Look in the details tab for error code and description.
ErrorCode - 85
ErrorDescription - Timeout
Restarting the PC completely resolves the issue as the bind then works at the next bootup and group policies are applied
The issue happens to one computer in 30ish so is proving very dificult to chase!
The issue does not happen to the same PC each time
Things I have already done:
Checked, double checked and treble checked our DNS infrastructure, all is perfect.
Disabled Large Send Offload on the Virtual NIC for our virtual Domain controller (one virtual and one physical)
I am completely baffled, can anyone shed any light on this? any help hugely appreciated :)
