I had to re-build an XP system from scratch. The system had been joining my SAMBA PDC OK. Before re-building, I made the XP system leave the domain and changed it to just being in the workgroup. I then did a "smbpasswd -x -m -XPPC" on the PDC. During the re-build I did not join the PC to the domain, just put it in the workgroup. One running I found that "View Workgroup Computers" failed with the message "<name of workgroup> is not accessible. You might not have permission to use this resource". I could examine other workgroups though. I put the PC back into the domain with "smbpasswd -a -m -XPPC". When I tried to join the PC into the domain I got the message "A domain controller for the domain <name of domain> could not be contacted. When I tried "nmblookup -B XPPC '*' on the PDC machine I got "querying * on <correct IP address" ... "name_query failed to find name *". I can only assume that SAMBA is remembering something about the PC which is now different. Any suggestions please?
