Thanks for your reply Vera. I rebooted the TS last night, so I guess we'll
see what happens today with this particular client.

Interestingly, I ran some tests[1] from home last night for two hours before
rebooting the server. I ran an automated test for two hours and didn't get
disconnected once. I rebooted the server at 23:30, and have been running the
automated tests since 23:47 until now (9:30) and still had no
disconnections. I will keep my 'test' login running for most of the day and
see how we get on.

I'll keep you posted!

Thanks again

Dan
