Dear Jamshed Qureshi,
the current configuration I use for my OpenACS installation (both Windows and Linux) is the one described here:
http://www.spazioit.com/pages_en/sol_inf_en/windows-openacs_en/I find this combination of software packages reliable and more than exceeding my current needs.
I haven't moved yet to Naviserver, nor I plan to move to it in the next few months.
You have in front of you three possibilities:
1. you compile yourself Naviserver;
2. you modify the sources of Aolserver 4.5.2 you can find in my distribution as required;
3. you can ask me to compile Naviserver for you, but that would be a consultancy job performed at these conditions: http://www.spazioit.com/pages_en/sol_inf_en/support_services_en/.
Hope it helps,
Maurizio Martignano
