We recently virtualized our isa server onto a VMWare ESXi host, and it was working fine for a while. We upgraded to ESXi 4.1 988178 which included new VMtools and by extention, new VMXnet3 network adapter drivers, so I put those in.

It seemed fine at first, but all of a sudden during the day the server will stop responding to pings. If I open monitoring I see Denied Connection messages with "A packet was dropped because the rate of requests for incoming connections was too high.". I've looked at the connection limits section and stuff like that with no result. There nothing in the logs that I can find that would explain this.

Anyone have any ideas?

I ended up removing a default route pointing at the ISA server from my backbone switch. Looks like I was getting hammered with SecureNAT requests from inside my network somewhere.

Now I'm dealing with other issues with a few vendor-supplied machines that do not have the firewall client and cannot access the internet, but things are working properly otherwise.
