I have windows 2003 Domain Controller having proper Primary DNS & Secondary DNS. I have joined all my Windows XP machine to this domain controller.
Every day few of these XP client machine throws the following errors. Rest of all are working fine.
"Windows cannot connect to the domain either because the domain controller is down or other wise unavailable, or becuase your computer account was not found"
Due to this error, I have to again join this Windows XP client to the Domain Controller.
