I was checking a remote 6.5 server and the following message was on the NDPS manager screen:

NDPSM-3.01-317 The NDPS Manager was unable to read the database file. Program execution may not continue normally.

The only option it gives is to unload the print manager. Currently the printers are working, so I don't want to unload it during working hours. On the database options screen which is open after I escape from the error screen the following options are present:

Restore Databse
Resynchronize Database Files
View log file
Delete log file
Uninstall database

I have not made any changes and nobody says they made changes. Any ideas on easiest way to fix this?
