I get different errors regarding "device in use" or "permission denied" depending on which way I try. I have access to this server and the directory structure. I can see the files in Exploring and open them in other programs (Notepad, Excel), but not Foxpro. Any thoughts?

>Going even further into left field, VFP makes use of file- and record-locking features of file systems that typically aren't accessed when you're opening files with other programs like Notepad or Excel. If there are privilege issues with these locking features that might explain things. On the other hand, I wouldn't think a simple SET DEFAULT TO would require locking features.

>Is it possible the server is somehow only letting certain registered applications access its files?

Maybe. Is there a way to check that? I have PCAnywhere access to the server.

>From your S$ syntax it appears the clustered server is Windows - is this actually the case? If so, which version?

Server 2000.
