Max Sessions on an XP workstation?

Hi,

I have several XP workstations in our domain that contain disks configured
for sharing. The workstations are all on the same network/domain which is
served by Win2K Server.

- What's the maximum number of connections (sessions?) that can be supported
by XP when its sharing a disk?
- Does a "Remote Login" session count as one session?
- What's the definition of a "session" anyway?
- Is there any way to automatically delete connections that have been idle
for a specified period of time?

Thanks Lou P.
