[Samba] Domain logins not working

[Gary Dale]

Further to the problem, I am still getting the same login error message 
on the XP/Pro workstation about being unable to contact the server, 
possibly because the server is down or a bad machine account. The 
server's syslog shows:

Jan  6 06:27:54 whenim64 smbd[1764]:   _net_auth2: creds_server_check 
failed. Rejecting auth request from client SHAFEENA machine account 
SHAFEENA$
Jan  6 06:27:54 whenim64 smbd[1764]: [2009/01/06 06:27:54, 0] 
rpc_server/srv_netlog_nt.c:_net_auth_2(478)
Jan  6 06:27:54 whenim64 smbd[1764]:   _net_auth2: creds_server_check 
failed. Rejecting auth request from client SHAFEENA machine account 
SHAFEENA$


The other logs show these same error messages or don't show anything 
relating to this login attempt. pdbedit -L on the server shows:

WARNING: The "printer admin" option is deprecated
