Hi Pavan,
Many thanks for providing the right information. issue was resolved. Yes it only supports windows 2012 but not windows 2008. As there was a PAM issue for us for couple of days we didn't get a chance to check the PAM for compatibility. As windows 2012 is very new and not yet still much matured i never though 2008 is no more supported.
Thank you so much for your time.
Kind Regards,
Hemanth
