I noticed this error message within some of my users log files; rpc_server/srv_samr_nt.c:_samr_query_aliasmem(2626) _samr_query_aliasmem: Not yet implemented. Why does this mean and what do I need to do to stop this error message from appearing. BTW, the users all have XP machines. Martin Stacey IT Support Manager Safcol Australia Pty Ltd
