File upload to remote fileserver

[PsypherPunk]

I've put together a webpage for uploading documents. The webserver is currently in a Workgroup while the fileserver, to which the files should go, is in a separate Domain.

The issue is that I don't seem to be able to read or write from this location. I've tried various parameters in the <identity> tag but none seems to work:

<identity impersonate="true" userName="DOMAIN\User" password="password" />
System.IO.IOException: Logon failure: unknown user name or bad password.

<identity impersonate="true" />
System.UnauthorizedAccessException: Access to the path...is denied...

Also, if I check the value of 'WindowsIdentity.GetCurrent().Name' during this, rather than being set to the DOMAIN\User specified above it's always set to the Webserver's MachineName\Username.

Any ideas where I'm going wrong?

Cheers.
