“No network adapters could be identified” error when choosing a network template in TMG

November 19th, 2010 Comments off

Some of our customers have experienced the problem described below when doing the initial network configuration of a fresh TMG installation. I wanted to share here the cause and solution to this issue.

Consider the following scenario
You have installed Forefront TMG 2010, but when running the Getting Started wizard, you get the error “No network adapters could be identified. The wizard cannot continue” when choosing the Network Template, see screenshot below:


We’ve seen this issue on servers where Operating System hardening has been applied prior to TMG installation. As a result, some services required by TMG to operate properly have been wrongly disabled causing the problem described above.

The solution and only supported way to perform hardening of a TMG machine is to execute the Security Configuration Wizard (SCW) tool and use the TMG security configuration template (XML file) matching your deployment in order to harden properly the server.

Note: By default, the SCW does not include support for the TMG 2010 role nor TMG Enterprise Management Server (EMS) role. To support these roles, download and install TMGRolesForSCW.exe included in the TMG 2010 Tools and Software Development Kit (SDK), available here.
