Re: Remote data access on LAN

If I understand it correctly, you want local execution but remote data
access for a remotely stored executable.

It might have been useful if you provided a specific error message or #, but
I suspect the problem is not finding the data, but an issue of
security/authorization. Btw, what is the transport protocol (tcp/ip,
netbeui, smb)?

I'm surprised you're not using RPC (Remote Procedure Call) for this app. Of
course, this would result in remote execution, which perhaps isn't what you
want. But it would avoid the current problem, it keeps data access local to
execution. You could use an RPC just for data retreival, though. The
reason an RPC will work is because it provides an authorization model. It's
either that, or use a formal protocol like FTP, HTTP, whatever makes sense.
Windows is probably not going to authorize remote data access via Windows
workgroup authorization, which seems to be what you are assuming.
