If h1nds1 stops running overnight and will not restart itself we have two options:

switch over to using h1nds0 as your NDS server (this is not the default, so you will have to force your client to use this)
reboot h1nds1 computer by going into the MSR and pressing the RESET switch on the front panel. Computer is clearly marked and is in the 5th rack from far wall.
