Thanks for the reply.
No, putting the short path in merely changes the error from the '404 or
dependancy error' to the 'Metabase access error' one.
Sorry, I omitted the name of the (internal) server from the error
description as it would not have been of any use to anyone, and I thought it
might confuse the post, but I have been using fully qualified pathnames at
all times.
I think you're right, IIS seems to be pretty messed up on that box. Think
I'll put this on one side until I can find another server to test on.
Cheers
David
