Hyper-v Manager fails to connect
Posted on 2011-03-09
I'm administrating a small network with a SBS2008 running virtual.
The virtulization server - named HOST1 - has a strange and annoying problem!
Sometimes the Hyper-V Manager looses connection with the virtual machines.
I can start the HV Manager and see the the local server name in the upper right corner but I can't connect.
The servers running virtual is NOT affected and is functioning normal.
When this happens apparantly the only thing I can do is restarting HOST1.
Restarting Hyper-V services does not help.
Any suggestions :-)

when you experience such problem , just check are you able to access sbs server through remote desktop. Also try reinstalling hyper integration service
I am fylly able to access the servers running virtual through Remote Desktop.
Nothing seems to be affected - except that I find it concerning that I can't use the HV Manager.
How do I reinstall the Hyper-V Integration service?? :-)

There are some known connectivity issues between host and VM. Try disabling DMA and Large Send Offload on the Host's NIC, as per the following article:
