I've had problems with this. Joining the XP box to the domain works fine, but logging on does not work. I get the message 'Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear, contact your system administrator for assistance.' In the log for the particular XP box, I see 'guest user (from session setup) not permitted to access this share (IPC$)' and 'error packet at smbd/reply.c(286) cmd=117 (SMBtconX) NT_STATUS_ACCESS_DENIED'. I assume this is what is being addressed by 3.0.2 as stated in its release notes. If so, I cannot find the particular bug in bugzilla. Is there any workaround? -- Kjell
