   Do you have a firewall in between. Firewalls throw away connections
   when there unused for a while,
   
For example, Sonicwalls have Network Connection Inactivity Timeout

   Try turning on KeepALive (or whatever the option is called now),
   
Also, there is how hard windows tries to keep connections alive.

This is in the PuttyFAQ
 
 The timeout value can't be set on per application or per session
 basis. To increase the TCP timeout globally, you need to add the
 following key to the registry
 HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\MaxDataRetries
 in Win95/98/ME (it must be DWORD in Win95, or String in Win98/ME),

 Then set the key's value to something like 10. This will cause
 Windows to try harder to keep connections alive instead of
 abandoning them.

P.S. Have fun doing regedit.  
P.P.S, do be careful.  This would be a good time to backup your machine.

   Your mouse has moved.
   Windows NT must be restarted for the change to take effect.
   Reboot now?  [OK]

Snirk.
