Hi there,

We have Ds 6.9 spk3 running for a while and more than 500 computers connected with Aclient working fine until now, what happen the last couple of day,  some machine show up White Aclient icon rather than blue, the message is "Connection closed; Session terminated". We follow some suggestion such as checking the version of the client and restart services but stil the same problem. The last resort is restart the server and then everything comeback to normal but we still do not find out what cause this issue..

I wondering if somebody else have similar experience...and how to resolve this issue

Thanks for your help in advance
