A family of Microsoft word processing software products for creating web, email, and print documents.
Hi Jim:
When you "save" a file to the network after you have been working on it, Word holds a lock on the file until Word is quit. Closing the file is not enough.
The "incorrect document syntax" error is a worry: it indicates that the save did not complete, or that the file you are opening is not the document (it could be one of the temporary files with a similar name).
However, if you have two computers networked together, you need one of them to act as the network controller and hand out a "Unique User ID" to "you" on each machine. If neither machine is a server, they can't do this. Chances are, they are relying on the default UUID, which is the same on both machines (501). If you set the UUID to something other than 501 on ONE of the machines, the fault will possibly go away.

Warning: If you are not skilled with the command line, leave that one alone: there is a possibility of locking yourself out of your home directory. Which is embarrassing! I know, I've done it :-)
Cheers
