I've got a fairly new client setup which has multiple offices, connected via MPLS to a domain controller, which resides on a VM in a datacenter a few states away. A couple of times a day, for most machines, I get event ID 1058, and 1054 in the logs. I can't for the life of me figure out why. There doesn't seem to be any actual issues. No problems logging on, from any of the locations. DCdiag is perfect. DNS is set correctly. Nslookup returns info as expected. No sharing issues or other access problems. Just these lingering events. If it wasn't for events in the log, there would be zero issues, and maybe there isn't, but I'd sure like to know what was causing them. Its similar to the issues in previous OS, where media sense on a nic would cause this, but I have disabled that on the workstations to no avail. Server OS is 2008 R2. All workstations are Windows 7 x64 pro.
The first Critical Blacklist Event found: Event ID - 1058 System log - Microsoft-Windows-GroupPolicy: The processing of Group Policy failed. Windows attempted to read the file ******** from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
a) Name Resolution/Network Connectivity to the current domain controller.
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).
c) The Distributed File System (DFS) client has been disabled.
