Build AX Enterprise Portal in Windows 2008 R2 DMZ network

As per request from our client, we need to set up the AX Enterprise Portal into DMZ network and provide the public URL to external customers to access.

I have built the EP with WSS 3 in Windows 2008 R2 but got the access issue if using URL while I can access the EP via the IP. Once I access the EP using URL, I am asked to enter username and password. After typing 3 times, I got a blank page. The error never occurs in Windows 2008.

After searching many documents in the internet, I got the solution from Redjockey’s blog (
that is to add the URL in registry on the IIS server:

  1. Click Start, click Run, type regedit, and then click OK.
  2. In Registry Editor, locate and then click the following registry key:
  3. Right-click MSV1_0, point to New, and then click Multi-String Value.
  4. Type BackConnectionHostNames, and then press ENTER.
  5. Right-click BackConnectionHostNames, and then click Modify.
  6. In the Value data box, type the host name or the host names for the sites that are on the local computer, and then click OK.
  7. Quit Registry Editor, and then restart the IISAdmin service.
