Control remote DCOM using ASP under specific account

[logx]

I have a bit of a problem which I can't seem to solve. I have a very simple script connecting to a remote server. It connects fine, however if I use "Administrator" account in IIS for the anon. access, it runs as it should. If I use anything else, I get an access denied error. The account I am trying to use does exist on the remote server with the same credentails, DCOM configured and proper permissions set.

Any thoughts on how I could use that particular account to successfully run this script are highly appreciated!
