Re: (ASCEND) Lan security error woes

Hi!

We seem to have the same problem here : MAX4000 with 2 times S2M (60
lines). 
Users are complaining about an "account allready in use" error which
seems to occur when a lot of users are online . Log Files show no trace
of abuse . Users logging in automatically (PAP) just get disconnected
...

Somehow I seem to have "lost" the Show Pools command , I just get

------------------------------------------------------------
Pool#                Base         Count      InUse
   1               141.51.15.3      67          0

 Number of remaining allocated addresses:    0        
------------------------------------------------------------

At this time about 25 Users were online and working ...

Hope Ascend fixes these bugs soon !
