[dba-Tech] Notwork Not working

Dear List:
 
I don't know what changed but on all of my computers, which are attached to
the router, When I click My Network Places-->view workgroup computers, I get
the message "Workgroup is not accessible.  You might not have permission to
use this network resource. Contact the administrator of this server to find
out if you have access permissions .  The network path was not found."

I have 5 computers on the router - HAL9002, HAL90004, and HAL9005, Marsha,
and Noah.  I get the same message on all when trying to view the workgroup.
All are members of the workgroup WORKGROUP.
 
Interestingly, any existing connection still works.  I have a shortcut on
the HAL9005 desktop to a folder on Marsha which still works.  I can even
navigate up the tree from that folder to her root directory

But I can't make any new connections.

Anybody know what might be going on here?  Could it be a setting in the
router?
