Network Policy Server Role won't install on Windows 2008

I recently had a weird issue while trying to install TMG 2010 (Microsoft Threat Management Gateway) on Windows 2008R2 where the pre-requisites wouldn't install and kept giving an 0x80072afc error

I narrowed this down to the Network Policy Server role which wouldn't install.

Googling the error "windows could not start the network policy server services" along with the error code "0x80072afc" revealed quite a few articles, mostly relating to missing permissions on the IAS folder within the system directory and/or active directory issues.

I decided to take a clone of another known-working TMG as a workaround, but on this box the Network Policy Server service wouldn't start which led me to believe it wasn't permissions related.


The fix I eventually found was much simpler.  I'd been trying to install TMG with the server in a workgroup and disconected from the network.

I plugged in the network card so the server picked up an IP from DHCP and Hey Presto! the TMG pre-req wizard then completed ok!
