samba - Mar 2007 - Error accessing trusted w2k3 domain share

We have configured a new samba domain that is trusted by a w2k3 domain (but=20
the samba domain doesn't trust the w2k3 domain) and the users from the
samba=20
domain are not able to access a share in the windows server.

The error they get is:
0x80070534: No Mapping Between Account Names and Security IDs Was Done.

This seems to happen only for one particular share, as they were able to=20
access other shares on the same server. All information I could find that=20
seemed to have any connection to the problem this was this:

The following error occurred attempting to join the domain "MYDOMAIN":
No=20
mapping between account names and security IDs was done. This obscure error=20
reportedly has been fixed by using lower-case names for the workstation name=20
in /etc/passwd and smbpasswd and on the Windows XP client.

Howerver, the problem didn't happen when trying to join the domain, nor do
the=20
workstation names contain any uppercase characters.

Any ideas as what is causing this and how to fix it?
Thanks
