Problem with a workstation connecting to a network

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?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

I would move it to WORKGROUP, reboot and move it back into the Domain

you could alternatively:
1) go to my computer, right click, go to properties.
2) go to the computer name tab and click on "Network ID"
3) Click Next, Next, Next, type in the username and password for a domain admin or administrator, and the domain name.
4) a popup will tell you the name was found in the domain, do you want to use it yes.
5) then select to not add a profile on the local machine.
6) click next or OK.

Make sure you are only pointing to Domain Controllers or Internal DNS servers in  your TCP\IP properties for DNS.

Seems like you are losing network connectivity or secure channel password needs to be reset.

I disjoined and rejoined the workstation from the network.  I checked the event logs and I didn't see any errors.  I was going to wait a few days before I click the Accept Solution box.  Is that acceptable?
You should not mark accepted until you have something that works.

If you have a DNS server on your network you will also find that your XP client will have an error/warning in it's event log for dynamic updates. you will need to delete the entry for this computer from the DNS and recreate it also since the security ID has changed.

That is fine when you remove station from domain then re-add you are reseting secure channel password if you don't reset the computer account you will see the issue again. You can use netdom to reset secure channel password without having to remove the station from domain
