Thanks for your reply.

This doesn't appear to be a very long time, however there are overheads
as there will be lots of other machines on the network (not configured
as thin clients), using citrix, exchange, domain services, and web etc.
I haven't at this point found out how many other boxes are connected to
the link, but will do so and factor in the bandwidth. I can no doubt get
some stats from the client in question as to current usage at that time
of day.

Once again, thanks for your help.
