I have 2 machines. Wired through a router. Originally 2000 was wireless but I hardwired it to remove any issue there.
Machine 1 is windows 2000 pro.
Machine 2 is XP home.
Router - Linksys BEFW11S4 etherfast wireless/wired router.
2000 machine can view shared files and has no issue.
XP machine will only occasionally connect to 2000 machine and most often it locks out my user account on the 2000 machine. If however, I do get the login screen all is ok for a while or until one or the other machine is logged off or restarted.
Each machine is in same workgroup. I even made a administrator account on the 2000 machine with the same name as the XP machine. The XP netwroking disk tool does not work on 2000.
I suspec there is some security issue I cannot find.
