Could you please let me know the version of Lightroom installed on the computer?
Also which operating system are you working on , Windows or MAC ?
Do you get the same error with any other file format as well ?
Please make sure that you have Read and Write access to the Folder in which you are trying to save the file.
I should - the files are being imported from a server that I have admin permissions to access. I'm trying to figure out a way to create a digital catalog of older finished files so I can easily bring them up with keywords instead of sifting through folders upon folders of old jobs without ending up with duplicates of files.

Put a copy of one of the problem files in /Users/you/Pictures and import it into your catalog. Does the problem still occur?
If it doesn't occur, there is some kind of permissions or compatibility issue with the server. If it does occur, upload the pic to Dropbox (or similar) and we can see if the issue happens to others and narrow down the problem.
I think I've found a solution. I opened up a Finder window and refreshed the connection to the server. After doing so, I was able to save metadata to the tiff file without a problem.
