Add TMG standard eition to EMS server

Hi All,

Purpose: Customer wants to manage all policies centrally where as respective users will use their owl location TMG server as proxy.

For this I have taken 3 server machine with below details.

Setup:

 AD Site 1: SRVEMS1 (TMG Enterprise edition, EMS Array created)

   AD Site 1: SRVTMG1 (TMG Standard edition, Added in EMS array 'TMGARRAY1')

   AD Site 2: SRVTMG2 (TMG Standard edition, need to add in EMS array 'TMGARRAY1')

I installed the TMG Enterprise management server role on server (SRVEMS1) and create a EMS array 'TMGARRAY1'. Later on I added one TMG standard edition server (SRVTMG1) into TMG Array.

Problem: While I try to add the 2^nd TMG standard edition server (SRVTMG2) it did not resolve the TMG array name TMGARRAY1 name. At that time it ask to create a new Array.

I do not know what is blocking to add the 2nd TMG to be add in EMS array.

Please help to resolve it.

Many thanks

Thanks in advance NKumar
