I realized I had a couple of typos above, here's the question again:

I've been spinning my wheels on this...I've read documentation etc and tried lots of different scenarios...still no go.

Say I've got www.abc.com hosted somewhere. I have successfully installed DNN 3.2 (their installer through Plesk) at www.abc.com/web . This works fine. I then created a child portal at www.abc.com/web/sting - still okay here....works fine when accessed through that address.

Now here's the problem. I've got another domain registered at godaddy - say it is www.xyz.com. I use their forwarder to point www.xyz.com to www.abc.com/web/sting and turn on the 'mask' URL option. I then make an alias for my sting dnn web for 'www.xyz.com'. Well I've tried this and dozens of other combos and still can't get www.xyz.com to work - sometimes I get the portal when using that URL but when I log in, my credentials appear to be accepted but then I just get the home page again, but am not logged in. I've tried with and without backslashes etc...and still can't get it to work properly.

Please help!
