The network is one win2000server 12 98machines and 3 xp machines. The XP machines take forever to logon to the server and during the day only a min or two they lose the logon. When attempting to do anything that requires the server access shared drive or database software the 98 machines are perfectly fast almost instant. While the xp machines act like they are going through authentication again. I looked at event viewer and here is what I see xp machine (SPNEGO) “The security system could not establish a secured connection with the server cifs/server. “source LsaSrv” and 1 more that is in Application that says source “autoenrollment” automatic certificate enrollment for local system failed to contact the active directory.The specified domain or could not be contacted. **** So I go to the server and here it is***** SOURCE NtFrs The file Replication Services has detected that the replica Set “Domain System Volume (sysvol share)” is in JRNL_WRAP_ERROR. ******* I realize something with the domain is not working My first steps when they started acting slow was to do a chkdsk on server now I want to be efficient and go straight to the fix help thanks jeff.
