I have a problem when trying to move my DNN site in my production server that installed with ISA Server.

After i installed DNN into my server that ISA installed, the default port of IIS change to 8000. So, all links in the DNN include the port in their url like : www.mydomain.com:8000.

The problem is from outside ISA Server known port number 80 but it translate into IIS with IIS default port (8000). I try to change the stored proc for PortalAlias table to remove the :8000 string after my domain name. It works to change all link in my domain. But i still have no access because the real port IIS is 8000. So i think i have to change some code in some file (i don't know what file it is) and recompile my DNN source.

Anybody can tell me how to solve this problem ?

Yikes!  It's always such a pain to install ISA on a web server....   Best scenario is to have a separate web server from your ISA server, and I use server publishing.. I don't use reverse proxy "Web publishing" and it works like a champ.

If you just can't do that.... and it all must be on one server,   www.isaserver.org is your friend.

However, you can definitely configure DNN to accept whatever port you'd like, and each site can accept multiple names/ports as well.

Admin > Site Setting >  Scroll to bottom of page.

Add new http alias:  www.mydomain.com:8000

So now you might have a couple listed here.
