OK, it appears that you are running a workgroup called 'TOL'. This means 
that all your users and groups need to exist on all machines and all 
passwords need to be in sync.

Have you checked that user 'xxxx' has the same password on all machines ?
Does the share actually get mounted on the machine you are denied access 
to ?
If it does get mounted, who actually owns the mounted share ?
