I have the same problem.  WorkgroupShare hang every 10 minutes.  When I look in the WGS Administrator under Output Window, the last line I saw in the log is:  unable to accept connection, too many clients.  My license if for 250 clients... I have less than 100 clients.  I'm using the Access database.  If I restart the WorkgroupShare services, it start working again, but 10 minutes later... stop working again... any idea?  Thank you!!
