Hi,
Like to seek help on our production machine Dell PE T620 (with tag =<ADMIN NOTE: Service tag removed per privacy policy>),
We might be having problems on the gigabit broadcom extreme network card or perhaps Windows.
We’ve setup HyperV on it:
1st VM running windows2012 R1 standard server Active directory server domain, DNS and DHCP services
2nd VM running legacy windows2003 standard server, for development/test environment & batch jobs
Both VMs are using the virtual switch manager to share the network connection.
Often times, We’re getting intermittent network problems on the VMs, ping test of very high latency (300ms-2000ms)
and RTOs to worst of NO connections on both VM1 and 2.
There are good days and bad days, worst case we had to restart VM1 and 2 to restore its operation and stability.
What could cause HyperV to loose network connectivity on the VM1 and 2?
The network (built in Intel Gigabit) on the bare metal OS seems to be stable, when the incident happens.
Another warning We're getting an exclamation mark (blue) on the DHCP service in the 1st VM,
but there are available IPs that are still usable.
Would appreciate any help.
