Consider the following scenario:

• The following policies are enabled on a domain controller that is running Windows Server 2003 in a domain:
  • Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft network server: Digitally sign communications (always)
  • Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft network server: Digitally sign communications (if client agrees)
• The following policies are enabled on a member computer that is running Windows Vista Service Pack 1 or Windows Server 2008 in the same domain:
  • Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft network client: Digitally sign communications (always)
  • Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft network client: Digitally sign communications (If server agrees)

In this scenario, Group Policy settings are not applied on the member computer. Additionally, the following event is logged in the System log on the member computer:

Date: Date
Event ID: 1058
Level: Error
Keywords:
User: UserSID
Computer: CompuerName
Description:
The processing of Group Policy failed. Windows attempted to read the file \\path\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.

Note: This problem occurs only on member computers that are running Windows Server 2008 or Windows Vista Service Pack 1 (SP1). It does not occur on member computers that are running Windows Server 2003, Windows XP, or the release version of Windows Vista.
