[Samba] "net sam set workstations ..." prevents users from using domain resources from non-domain member systems

[Chris Smith]

Running into a serious problem here with 3.0.24 + patches.
The shop has a mix of domain member computers and privately owned non-domain 
member computers. I'm trying to use "net sam set workstations" to limit the 
workstations domain users can log onto. This limitation works as expected. 
And domain member workstations all work properly.

But once the workstation limit is put in place the users on their own 
workstations (non-domain member boxes) can no longer access domain resources 
such as mapped drives which they could previously do after supplying the 
proper credentials. Now even with proper credentials Windows 
returns "unexpected network error" when these users try to use the domain 
resources. If I remove the workstation logon limitation all works again as 
expected.

Is there a fix for this?

Thank you,

Chris
