I have setup a test Hyper-V server. Installed 2 virtual machines. Both are running and network connection from these to "externan" is fine.

But: From external to these machines only one is ok.

The other one is very unstable. Looses network every 2. min. No errros in any logs. I have seen this on VMWare to, but never seen a solution. Anyone?

Just realized:

I'm working on the system through a ISA vpn.. I can ping both servers from the machines on the internal network. But ping from VPN client are the issue.

Hello jakobmarkussen,

What are the guest os versions? Do you have the RTM version of Hyper-V installed? Have you installed the integration services disk on both VMs?

What network cards are you using in the host system?

What version of Windows are you using on the guests? Are there any differences on the guests?

Does this only happen when they are both on, or does it happen when only one of them are on?

Do you have any type of packet filtering or firewall software on the host or guests?
