Problem with individual forum access.

Ok. Here's the story, then I'll tell you the result.

Originally, I was redirecting towtalk.net from a remote server to a specific ip and file location:
towtalk.net -- http://206.168.97.226/towtalk/forum/
Couldn't get email working. SO

I did a custom DNS, towtalk.net is now pointed directly to my machine and at the forum.
Then I installed the email server, created an MX record and got all the email working on my server. Problem solved.

New problem:
The forum is in the webroot/towtalk/forum/ directory. My IP address drops the user right into the webroot. Now, if I create a redirect default.htm page right in the webroot, it moves them right where they need to be, no problem and everything works fine. But I thought I'd get fancy and I made the /towtalk/forum/ the home directory for towtalk.net.

I didn't change anything on my machine as to where the forum actually resides. I tested the forum and everything is still there and everything works, except for one thing.

Specific forum topics can't seem to remember my password as I try and view a forum topic that require permissions beyond "anyuser". If the topic has ten posts, I have to enter my password ten times! LOL. I am still logged in as a qualified user and I can view anything once I get past the password but once I close it, it doesn't remember that I'm approved to be there and asks me again.

What the hell did I do and how do I fix it?

Help? I am sure it's simple, I just have no idea where to start.

Yeah, I been doing a little research since I posted this. I think I'll leave it the way it is. Seems to be working just dandy. I am installing the iportalx so things are gonna get changed around a bit. I will probably do the same thing with that. The DNS points directly to my webroot folder. I could change it but almost seems like more hassle than it's worth.

Oh, In win2003k, you can right click on the webroot folder and pick a new "drop" folder. That's what I did. So when someone entered towtalk.net, they were redirected once they reached the webroot folder to /towtalk/forum/ and it didn't show in the address bar. I think you are right, the "stealth" technique caused permission problems.

Obviously my explanation and technical terms are from the backyard school of computer mechanix and makes more sense to the "layman" LOL I do appreciate your input.
