My network has domain model setup. We have one domain & all the machines are Windows XP configured for same Domain. When logged in with domain account, there is no problem in accessing the other machine, shared folder, drives, printers. But if in any machine I logged in with Local user account ( Local administrator ) and I try to access other XP machine it shows the policy error. It doesn't give you the option for authenticating to that machine also. But in same way if I access any NT machine by logging with Local administrator, it allows me to enter the information to authenticate with network. It means this problem is for only XP. I tried several policy level option but could not get solution. Can you help me pls?
