Hi, I have one domain (DOMA) on a network 10.108.x.x mask 255.255.224.0 and DOMB is on 10.251.x.x mask 255.255.224.0. These domains are connected accros a WAN. I wish to set up a trust relationship between the two. DOMA has a samba 3 PDC and DOMB is a WIN2K PDC. The problem I'm having is the Samba PDC can't see the DOMB domains PDC. I have set up the intertrust accounts on the samba server and if I do net rpc trustdom establish DOMB I get "Coulnd find domain controller for domain DOMB". If I do smbclient -L 10.251.1.1 (DOMB) I can see the PDC for DOMB. IF I do the same on 10.108.1.1 (DOMA) I can see the PDC for DOMA. Should each PDC have the other PDC in there workgroup list?? I would welcome any ideas on this. Cheers Kristyan Osborne IT Technicain - Longhill High School 01273 391672
