Authentication for write permissions can be a tricky thing in a hosted
environment, if you have been given write permissions at all.

I would guess that the hosting provider denies write at some point in the
path
 "c:\xxx\xxx\xxx\csgallagher\xxx\SomeFile.xml" is denied.
at a level below your application.for the asp.net account, so even
impersonation is unlikely to help as you have found.

Your next step is probably to drop them an email outling the problem, even
passing them a small code sample. If they are any good as a hosting
provider they will be able to tell you straight away what the problem is and
resolve it for you.
