My computer keeps disconnecting mapped network drives.

This behavior is by designed.

This behavior occurs because Windows NT Server 4.0, Windows 2000 Server, and Windows Server 2003 can drop idle connections after a specified time-out period (by default, 15 minutes) to prevent wasting server resources on unused sessions.
