I just created company's website based on DNN 4.8.2,  and it works very well on internal. But when I moved it to ISA server 2004, and open home page, it just display the image and link on home page.

The menu and all skins are lost.

Anybody can help?  Many many many thanks in advance.

Thanks Chris.  Let me describe my problem more detailed, so maybe can get more detailed help.

Based on current situation, I have to install the web application and Database on ISA server. The domain name is www.abc.com, and the IP is 69.121.122.123. 

Here are my I did:

On DNS:

1. Set www.abc.com to 69.121.122.123

On IIS:

2. Create virtual parth "webportal" under Default Web Site;

3. Set Local Path to "D:\webportal", and Enable Defaulto Document to "Default.aspx";

On ISA Server:

4. Set HTTP to 69.121.122.123, and set Port to 80

5. Set Internal Parth to "/", and External Parth to "/webportal/*"

On DNND Database:

5.  Set HTTP alias to www.abc.com/webportal

Based on my test, I think the point is the parth setting on ISA confused the HTTP alias in DNN Database. But I tried all the combinations, and none of the work well.

Again, help please and many many thanks.
