The proxy is just that - a proxy. The method will be executed on your
remote object, so the file will be written on the remoting host's file
system. Assuming of course you are marshaling-by-reference - your remote
object is derived from MarshalByRefObject. Server.MapPath() should work.
It should return the physical path associated with any virtual directory you
specify. Just be sure you have write access to that physical directory for
the identity your remote objects/ASP.NET application are running under.

Good luck.

Thanks,

Sam
