Hi folks, I'm playing around and trying to teach myself some basic samba stuff. I got the system setup as a PDC no problem win xp clients logging in. Everything working well. Then decided could i set up a second pdc for a different domain got this working fine to, then created a 2 way trust between the 2, with a view to the following. Domain A pc1 user a Domain B pc2 user b What i want is for user b to be able to use pc1 to login to domain B. Now user a on pc1 can log into domain A user b on pc2 can log into domain B But user b on pc1 gets domain not available. I ran net rpc trustdom lists on both servers and trusts appear to be set up correctly there. Any help please Pete I
