Digi One Sp

I have installed the Digi One SP on our network, the installed the Realport Drivers across 2 virtual servers. This has been working well until now. The digi One will not drop the connection to one of the servers even when the server VS is turned Off.
If I restart the DIGI One it drops it, can’t drop the connection via the web interface.
Anybody had a the same problem or can help ?

forgot to say:
Model: Digi One SP
Firmware Version: Version 82000774_G 07/06/2005

It sounds as though you may want to configure the Digi One SP to timeout after a period of inactivity:
