I have a small network with one server running active directory, when i try to access group policy for the domain or domain controller either from administrative tools or within ad users & comps, i get an error message, it is either 'the network name could not be found' or 'the specified domain does not exist or could not be contacted'. I thought it might be DNS but i have run netdiag /debug and everything passed (DNS was OK) except for these two errors:- ************************** Domain membership test . . . . . . : Failed [WARNING] Ths system volume has not been completely replicated to the local machine.

the machine should be able to recognize itself; something sounds torched. add another DC to your forest and see if this repairs replication. otherwise, you could try formatting and remaking the AD domain as you are on a small network anyway.

You could as well try unloading the WINS service, erase all the files located on %systemroot%\system32\wins and restart your server to see if it solves the problem. Andrés
