The path I am trying to create is correct.
I checked the knowledge base and I think the problem is due to the fact that
D is a mapped network drive while the asp.net worker process is a local user
that has no network access and thus cannot access the network drive.

If that is true then
1. How creating a directory with old ASP FileSystem object works fine?
2. How come creating\reading\writing files in existing directories work
fine?
