ProcessGPOs: Processing failed with error 59


I have searched but can't find an answer to this problem........

Some of our users are getting an error message during logon to the effect that their profile cannot be downloded because of a network problem or permissions problem.

Our application logs show an event code 1504 and the error "Windows cannot obtain the domain controller name for your computer network. (The specified domain either does not exist or could not be contacted). Group Policy processing aborted."

I've swithced on the logging feature and can see errors  "ProcessGPOs: Processing failed with error 59" and "ImpersonateUser: Failed to impersonate user with 5".

When pinging clients from the server we get very erratic ping times.. sometimes sub 1ms sometimes a negative number.

Thing I've tried so far: reboot switches, check DNS is all OK, manually point clients to DC, install latest Gigabit Ethernet card driver.

Would be greatful for any help!

I think I've solved it myself.

It appears to be due to a problem with a clock drift on AMD dual core processors. See here.....

Check to see if there are any old false pointer records for the computers in question?? If so then delete them and try again....Also have you performed an nslookup on the clients in question, does the IP they actually have assigned to the computers host name match up?? This is also a good way to see if false pointer records exist for the clients in question...

Hope it helps :-)

Sorry if I'm asking the obvious but how do you determine which are the false ones?

Also I've tried setting "group policy slow link detection" to zero in a policy object that applies to the client pcs but that has had no effect.

Thanks fo any further advice.
