I am having the same problem, and I'm kind of a newb in DNN, so I probably don't understand the difference between child/parent portals (is there a document somewhere I can read??)
I have my "main" portal which was setup when I installed DNN (4.03), and I now added a new portal via host->portals->add new portal. I had setup my IIS to point to my DNN directory. So my setup looks like this:
IIS:
localhost/portal1 points to my DNN directory (which is in inetput/wwwroot/dnn4)
localhost/portal2 also points to my DNN directory (which is in inetput/wwwroot/dnn4)
and I have two portals setup by the name of portal1 and portal2, each configured to find the alliance localhost/portalN where N is the number of the portal, with portal1 beind the "main" portal I started with.
For some reason which is beyond me when I access localhost/portal2, it always redirects to portal1!!
Please, can someone wiser than myself explain what it is that I'm doing wrong??
Thanks!!
