Mike,
I posted the message from (DNN's) error log already, so there is no need to re-post it.
In the IIS log files, I found that there is an automated forward to WindowsSignin.aspx, and the DOMAIN\UserName appears in the log. I tested this with Classic and Integrated mode, both in full trust.
In the meantime, I found out that you posted something about this. You wrote:
[QUOTE from here]
- The IIS 6 Metabase Compatibilty needs to be installed (I installed all but the IIS 6 Management console). Otherwise an error appears on the Settings page an the provider is unable to test whether the site is running under the correct pipeline.
- Impersonation has to be used (see the documentation for instructions on using impersonation).
- The user used in the impersonation has to be part of the administators group on the server.

Well, I do not like the idea in 1), but if it works...
... and I do not like the idea in 2), but if it works...
... but 3) is not acceptable. This would mean that every user has administrative rights on a server in the company's infrastructure. No, no, and again: NO.
Hope you can fix this. And the two others as well.
Best wishes
Michael
