Hello,

  

Win2008 is supported from ACS ver 4.2 patch 4 onwards, so you need to upgrade your ACS to 4.2(latest patch).

ACS 4.2.0.124 cumulative patch for windows can be downloaded from this link,

http://www.cisco.com/cgi-bin/tablebuild.pl/acs-win-3des

Also
ACS is currently not supported on Win2008 R2 (ACS running on win2008 R2)

So make sure you are running acs 4.2.0 with latest patch or 4.2.1.
