map drive problem

["Jim Franz" <franz400@xxxxxxxxxxxx>]

I am accessing an i5 at v5r3 via Windows Terminal Server (their requirement).
Had defined 2 map drives over ifs directories. 
When I logged on today, one drive (in Windows Explorer) has the red "X" to 
indicate it's not connected. Both drives were created with reconnect at login.
I bring up iseries navigator, >file systems>file shares> display the shares, 
right click - no options to end connection, or restart it. Can't remove it and 
re-create...All I see is open, explore, properties. No options grayed out. 
How can I check status and get it to reconnect?
Any log entries to look at as to why did not reconnect at login?
Have a network server product that needs a mapped drive to ifs & i need it 
to always be on, and reconnect whenever either side might reboot.
