Hyper-V console dropping when using a VM

[FN-GM]

Hi,

 

I get the following when i try to use all VM's on our hyper v server. Does anyone have any ideas?

 

I have done the following:

Bios Update

All Driver updates

Windows updates

Re-create the virtual machine

Remove all AV

Disable firewall

 

The network connection is fine and working perfect.

 

The host and virtual machine is Windows Server 2008 R2 Enterprise. Its on a Dell Poweredge 2950 using 16GB Ram.

 

Any ideas please?

 

Thanks

I take it you have a single link to the network on the physical?

does a ping -t show any dropouts when it happens?

Can you ever connect?

The network is perfect. Each VM and the host has its own nic and it works fine

Its more I have heard about issues with the physicals having 2 nics plugged in more then anything and random packets could be lost (thus the ping test)

Does the console work at all?

I think ZeroHour is correct. I've had similar problems with VS2005R2 with multiple NIC's. Is the console connecting to the server via IP address or domain name? If it's the domain name, have you tried using the IP, if so do you get the same problem?

 

Are the additional cards registering their IP with DNS (they shouldn't be) and when you look under the cards properties is Windows Networking listed (again shouldn't be)? The additional cards should be issolated so only the connected VM's traffic goes accross them.

Sound a bit similar to this problem, but probably unrelated.
