Error sending Shell commands - No such session or session has been closed

From the Admin. Client Server Console I issue a shell command e.g. $dir c:. As the server controller is running on that server I get prompted to connect to server controller using my name and Notes password.

The client then just takes for ever to respond so I hit Break key to interrupt command. I try the command again but only get the error message:

“No such session or session has been closed”

Anyone else having problems with this kind of thing? Any advice to get it all working? I am working with Full Administrator Access.

Cheers

Jon
