[Samba] question about AD authentication

[Delagarza, Gilbert]

what does this mean?

[2004/02/26 09:09:15, 0] lib/util_sock.c:get_peer_addr(952)
  getpeername failed. Error was Transport endpoint is not connected
[2004/02/26 09:09:15, 0] lib/util_sock.c:write_socket_data(388)
  write_socket_data: write failure. Error = Connection reset by peer
[2004/02/26 09:09:15, 0] lib/util_sock.c:write_socket(413)
  write_socket: Error writing 4 bytes to socket 5: ERRNO = Connection reset
by peer
[2004/02/26 09:09:15, 0] lib/util_sock.c:send_smb(605)

I see this in the logs from a W2K server in AD when I try to map a drive to.
I get challenged by a userid and password box.
Any ideas?
