I work at a small company which has 30 or so computers, most are running Windows XP Pro and a handful is running Windows 7 Pro. All computers are connected to a WIndows Server 2003 domain. I am having a problem with one computer locking up intermittently, it locks up for about 5 minutes then it is fine. I viewed the Application Event Viewer and noticed that around the same time as the lockup the PC thru an error, event code 1053 which states "Windows cannot determine the user or computer name. (The RPC server is unavailable. ). Group Policy processing aborted." Also around the same time there is another error "Automatic certificate enrollment for local system failed to contact the active directory (0x8007003a). The specified server cannot perform the requested operation.
Enrollment will not be performed."
Could it be a DNS issue? How can I fix this problem?
