I reinstalled my domain server 2000, all 3 of my xp pro system can log on to server and communicate with each other, but two of my xp pro workstations cannot add any users from domain on the share access list. on other words, when I share a folder or printer and click on the security tab and try to add a user from domain, the location option only shows the local machine name and cannot be changed to domain. so, only I can add local users. Also same when sharing a printer and cannot publish it to AD. Any advice to resolve my problem will be highly appreciated.
