samba - May 2000 - ERRSRV - 2242 (On NT Wkts)

I'm using Samba 2.0.6

We mount( -smbfs)  6 NT Workstations on Linux using this version of Samba.
The Linux version is RH - 6.1
One NT Workstation has problems getting mounted. Samba returns the
following error "ERRSRV - 2242"
It has NT SP 5.0

Please advise, if Samba 2.0.7 has a fix for this.

Thanks,

Satish.
