I am using the DRACT but am having some problems discovering dracs which I know are online. 

I am using DRCAT on a 64bit server with the unofficial tweak getting it to run in 32bit mode and I can discover *some* of the dracs on our server management vlan. 

There are some dracs though which I just can't get DRACT to see. I can browse to them via my web browser from the sever I am running DRACT from, ping etc all fine but DRACT just says discovery completed and shows nothing? 

There are DRAC5 and iDRAC6's which I cannot see. Do they need to be at a specific firmware?

Any ideas? Thanks, Kris.
