Are you saying the printer can scan to the share fine until rebooted, at which point you start getting the error code?
Are you using a Network scan template or something else?
I really don't understand the line When I click on domain name in xerox display there is a list with computers inside domain, but now i cant find domain controller on this list., what list and where are you choosing this? Try providing pictures and screenshots in your reply
If the printer is not registered on the domain it won't properly browse it, and the username should be formatted as domain\username if server 2003 or older, and user@domain for server 2008 and above. Easiest way to be sure is to check the share properties, it doesn't matter how other devices are configured, this one needs to be done this way
