Hi Chad,

here is the VMware document link to the Advanced HA options:


However, there are a lot of advanced settings I've not been able to get hold easily, i.e. Advanced DRS options.

I'm currently trying to put a wiki together to start collecting all advanced options. I'll let you know when I make it visible online.

Cheers, Forbes.


I had the same issue a while back in a classroom setup. I just changed the gateway to temporarily fix it. But this is a better solution! Thanks,

Chad Sakac
