Samba / XP login failures while tring to access shared files (works with win2k)

I got samba running on a redhat box that is also my dhcp server,firewall, NAT, etc... anyway.. On my win2k box I can login to my samba system and access the shared files, however when I try to use my xp box I get this error:

Standard you dont have permissions error plus this:

You were not connected becuase a duplicate name exists on the network. Go to System in Control Panel to change your computer name and then try again.

Now thinking that XP was right I did what it said. (waste of time) I changed the name to something that would never be on my network nor that I have in any configuration file on any of my systems... same error.

Im not to good when it comes to dealing with xp, I wouldnt use it only the software I use to program a fpga board is only available for xp (school related)

Does anyone have any ideas?

You know I have the same problem too ( well almost)... I have a network with 8 machines.1 machine is a Redhat 9 server for files and printing and 6 of them run windows xp and then 1 uses Win 98.

So I created usernames on samba( the same ones which are available on windows with the same passwords).but when I login to server form either 98 or xp .... the login fails.

Sometimes if i use the smbpasswd fronted ,passwords works but only for couple of hours and then the next morning passwords don,t work.So if anyone could help ... their help is very much appreciated.

OK I fixed my problem !!

This seems to be a issue with 2K and XP but I only had trouble with xp..
to fix...

The Windows XP (and probably the W2K) requires set an special registry entry to "0" (by default is set to "1"). This is documented in the samba/docs/Registry/WinXP_SignOrSeal.reg :
; This registry key (gathered from the Samba-tng lists) is needed
; for a Windows XP client to join and logon to a Samba domain

Also, Luke Howard <lukeh@PADL.COM> (9 Nov 2001), tell me:
I noticed today that you can change this in the Local or Domain
policy editor in Windows 2000, too.
so, this should be the normal way.
Qouted from:

scroll down to contents and click on # 16. Windows XP and W2K requirements

Hope this helps anyone else using samba!

To edit the registry log in as administrator or user with admin rights and clikc on start->run regedit use tabs to find the right file.. double click on RequireSignOrSeal and change to 0.
