after working a while we recognised that the members of the local groups "builtin\administrators" and "builtin\users" on our filers (760 6.0.1R1) are now in the "user unknown" state. that means the usermanager from nt is not able to give us the "domainname\domain admins" and "domainname\domain users". in all other local groups the names are displayed correct. also the given permissions are ok, and we are able to administer the filers. but - how to fix this problem?

is ther anybody out there ... who solved such problem?
