I tried to install Exchange 2007 Edge Server on three Windows 2003 x64 R2 with the latest windows updates, also, I have configured the server with below settings:

1. Configure DNS suffix for edge server

2. Install .net framework x64 & ADAM

3. Install .net framework security hotfix KB926776

4. Install Power Shell 1.0 International English

5. MMC 3.0 (Windows 2003 R2 built-in)

Before I launch Exchange setup wizard, I configure NIC on the server where the Exchange 2007 Edge server role will be installed.

As you know, because Edge server  has two NICs and locates in a DMZ, so, I unbind Client for Microsoft Networks & File and Printer Sharing for Microsoft Networks on external NIC, this is for security purpose, you know.

Final, I launch Exchange 2007 Set wizard from local DVD-ROM, during Exchange BPA, I was told the below error messages:

Summary: 1 item(s). 0 succeeded, 1 failed.

Elapsed time: 00:07:28

Edge Transport Server Role Prerequisites

Failed

Error:

There was a problem accessing the registry on this computer. This may happen if the Remote Registry service is not running; it may also indicate a network problem.

Elapsed Time: 00:07:28

At the beginning, I very confuse with this message, remote registry service is definitely running on local computer.

Finally, I found that this is because I remove Client for Microsoft Networks & File and Printer Sharing for Microsoft Networks on external NIC, after I restore to default setting, Exchange setup continues.

After I successfully installed Edge server, I removed Client for Microsoft Networks & File and Printer Sharing for Microsoft Networks on external NIC again, but this will be NOT having impact to Edge server.
