I have two users who are denied access to the root folder of the Samba Share. 
I have been able to access the root folder in the past but all of a sudden I 
was denied access. However, if I log on as Domain Administrator I have access 
to the root folder. If I log on as myself, I am unable to access the root 
folder. All other users/computers are fine. I took my computer off the domain, 
renamed the computer and changed my password but I still had access denied 
errors. I looked at the log for my machine:

lib/util_sock.c:get_peer_addr(978)
getpeername failed. Error was transport endpoint is not connected.

lib/util_sock.c:write_socket_data(413)
write_socket_data: write failure Error = Connection reset by peer

lib/util_sock.c:write_socket(438)
write socket: Error writing 4 bytes to socket 22: ERRNO = Connection reset
by peer

lib/util_sock.c:send_smb(630)
Error writing 4 bytes to client. -1 (connection reset by peer)

smbd/service.c:make_connection_snum(619)
robnevin (192.64.80.88) connect to service Public initially as user
PROTEXIONPRODUC+alex (uid=10047, gid=10000) (pid 18829)

I ran smbstatus -v -u=alex and got:

PID        username        group                    machine
18829    alex            Domain Users        IT
opened /var/lock/samba/connections.tdb

Service            pid            machine            Connected at
Public            18829        robnevin            February 4, 2005

The odd thing is if I open Explorer, and type in 
\\Samba\RootFolder\Groups\SubDirectory in the address bar, I can get access. I 
just can't drill down to the folder (if I'm saving a file). The machine is 
running Windows XP Pro, the samba version is 3.0.5 and the domain controller 
is Windows 2000 server. It is not a time skew as the computer is only a few 
seconds out from the server. Thanks
