Date: 6/25/2007 3:20:07 PM
Event ID: 1058
Task Category: None
Level: Error
Keywords:
User: x
Computer: PC01.domain.local
Description:
The processing of Group Policy failed. Windows attempted to read the
file \\domain.local\SysVol\domain.local\Policies
\{86EF0A30-42C9-4AEC-8231-6D31DC628A10}\gpt.ini 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.
