Thanks for posting this. I ran into the same problem on my new 2008 R2 server and even though I have IPv6 off it would not work until I entered "-Xmx512MB -Djava.net.preferIPv6Addresses=true" for the java enviroment.

I already have tried that and it doesn't work for software updates.

Thanks anyways JustinY

I contacted Open Manage support and the correct line for the java console must be:

Normal 0 false false false EN-US X-NONE X-NONE -Xmx384M -Djava.net.preferIPv6Addresses=true

or

Normal 0 false false false EN-US X-NONE X-NONE -Xmx512M -Djava.net.preferIPv6Addresses=true

or

Normal 0 false false false EN-US X-NONE X-NONE -Xmx1024M -Djava.net.preferIPv6Addresses=true

If you have enough RAM you can use 1024M.

Regards.
