Which LV Version are you using? Which VI's are you missing? Which Win2k service pack are you using?
There was once a problem with the DAQ & File I/O VI's under Win2k SP2. You have to check if the llb's where your missing VI's are placed,have the right permissions.
For DAQ & FIle I/O VI's:
Go to the LabVIEW 6/vi.lib/daq directory as an Administrator and make sure all
the .llb files gave Read and Read & Execute permissions to Power Users and Users. After this you
reboot and logg back on as a non-Administrator. The vi's should show up on the palette now.
The same thing to get the missing file i/o VI's to show. Set the permissions correctly
for the file LabVIEW 6/vi.lib/utility/file.llb.
Hope this helps
