There was a bug in VMware tools which could result in loss of network settings on upgrade to hardware V7 in some circumstances.
Supposedly fixed in the latest tools, but I haven't tried any V4 -> V7 updates recently. If you want to be safe, follow this sequence: snapshot install latest tools and reboot shut down snapshot upgrade hardware version start VM pray to your favourite $deity wait for drivers to install reboot test (forget to) delete the snapshots You will, of course, have to redo any MS NLB when you change hardware versions (because the underlying adapters have vanished and been replaced).

What it might have been is the VM hardware version upgrade that you should do when upgrading from 3.x to 4.x. That can bite you fairly easily.

Something to do with the tools upgrade messing with the NIC drivers, I think, but not positive. >>> Martin Blackstone <mblackst...@gmail.com> 2/24/2011 10:35 AM >>> You will probably need to upgrade the VMWare tools on the guests.
