I take it you have everything on the network path - MAP.INI included.
If you had this local (eg. c:\cam) and just setup the database, items etc paths to be networked then you would get a warning message "Corrupt Database" if the network paths were not available.
I'm not sure what you would expect the program to do if the 'Start In' folder for the application is not valid, as without a MAP.INI the program doesn't know where to look for any of its files.
There is a fallback for this situation though - if the registry key
"HKEY_LOCAL_MACHINE\SOFTWARE\MAPLTD\PM2000\Install Path"
exists and that points to a valid alternative installation folder where a MAP.INI resides then the program will automatically switch to using that to locate it's files if the original 'Start In' folder is not available.
