Thanks for the reply - does not really help me though - you are describing a working situation using the things I have tried - but it just does NOT create the sub-folder at all. I am running on vista - but using a public folder (c:\temp) so permissions are not an issue.

One other poster had a very similar issue, and it was solved by some example sent by Harold Klopper? That I am sure would help me.

Also as an aside, does anyone know if using the schema cache (from 2nd connection onwards) improves the speed of the actual connect? And by how much?

Best regards (and getting desperate)
