samba - Jun 2003 - samba 3b, windows xp, not sure what is wrong or where its going wrong, this might be it?

All of my services in windows xp shut down after a couple hang... Error 
messages are abundant on both the XP system and my samba box, and I'm 
trying to approach the problem from all angles to figure out what 
exactly is causing the main errors.  The following shows up in the 
machine's log on the samba box, and hopefully will be of some help.  I 
can post any other error log/configuration files that you think may help 
as well, just let me know:

[2003/06/24 17:17:06, 2] 
rpc_server/srv_samr_nt.c:access_check_samr_function(115)
   _samr_query_groupmem: ACCESS DENIED (granted: 0x00000001;  required: 
0x00000010)
[2003/06/24 17:17:39, 2] smbd/server.c:exit_server(558)
   Closing connections
[2003/06/24 17:18:21, 0] lib/util_sock.c:read_socket_data(342)
   read_socket_data: recv failure for 4. Error = Connection reset by peer
[2003/06/24 17:18:21, 2] smbd/server.c:exit_server(558)
   Closing connections


At 17:18 is when all the services on the Windows XP machine 
hung/terminated, so I feel that these error messages are definitely 
related.  Searching for these errors didn't help much.  Searching for 
the XP error messages hasnt helped at all.

Please help!
