Virtual Machine loosing network connections at random

Hi All,

A Virtual Machine that contains Disk2VHD image of a SBS2008 server resides on a Server 2012 R2 Host.

The Host is a Gen 8p HP ProLiant with four NICs so the VMs have a NIC each. There is one other VM on the Host which is a Disk2VHD 2003 Server with (so far) no issues.

The SBS08 has one vNIC assigned to it and when the VM looses its network connection, I log on to the Hyper-V host and assign another vNIC to the VM and the connection is restored. Then days later it looses connection to move it back.

- SR-IOV was enabled and disable, no difference
- MS WFP is enabled
- Changed network cable even but no difference

All NICs are connected to a 48 port managed HP ProCurve switch.

Does anyone have any ideas?

Thanks,

-GNS

I disabled VMQ on the current NIC to see if that will help.

Move the server to another virtual NIC that does not have such issue.

There is no valuable reason to have a dedicated hardware NIC per virtual machine, unless you have very heavy network traffic.

If the issue persist, try reinstalling the Integration services.

Yes, thiis is a sadly common issue with HP NIC drivers. Make sure you have updated your driver to the latest version.

But all machines within the same building (192.168.2.x and 192.168.6.x) can access it no problem, only from the remote site (192.168.1.x) there is connection issues, to only that server, so that would not be the Drivers.
