I hae two Hyper-V servers installed on 2IBM 3650 Machines. I installed two Win 2003 on ach Hyper-V soin total I have 4 win 2003 server SP2
I noticed lately that most of my 2003 servers hosted on Hyper-V 2008 are getting disconnected from network for a while and after that their performance gets very bad for about 20 minutes.
I check the event logs and found the following warning
Event id: 5
The miniport 'Microsoft Virtual Machine Bus Network Adapter' hung.
This warning is always followed by another information message
Event id: 4
The miniport 'Microsoft Virtual Machine Bus Network Adapter' reset.
I monitored the disconnection and I found that those messages are appearing just when the disconnection happens. I searched the internet and I found a lot of discussions regarding this error but no exact solution is posted and nothing posted by MS too.
