I have a problem with my file server. It is running Windows Server 2003 with active directory and windows xp i map share folders of my server to some drive letters. but after period of time (usually happen in the afternoon @ around 4pm onward) after i login if i click on network drive i get an error of logon failure, but after i logoff and logon again the problem will solve. Is there's a something wrong with my setup? I only share the folder manually... thanks a lot co... espiya's
