Can't save with any office 2007 excel or word files to shared network

All of a sudden we are not able to save any files to a shared network drive when using excel or word. We are able to save locally, to the C: drive, and then with windows copy to the shared network folder. We can use excel or word to open from a shared network folder, just cannot save it. The only thing that has changed is we had 10 updates recently and this morning when we started our machines, the problem started.
