Hello,I'm getting litterally crazy over this issue and i don't know what to do exactly.
Basically, the issue is so weird that i wouldn't be able to define where to look (tried for 15 hours in a row).
I have this server running Windows Server 2008 R2 DC Edition. The guest are running the Standard one.
Basically, the remote desktop connection stopped working on a few VMs with no explanations. There is no RAM outage neither on the Host nor the guests and there is a connectivity to internet in each VM affected. I removed the firewall to check whether it would fix the issue and it didn't.
After a few hours, I discovered that if i initiate a ping to an IP from a non working VM, it is fixing the the Remote Desktop Connection program. The first ping has a latency of 1000ms while the 3 others are regular (40ms). It is working for a while (from 5 to 30 minutes) and it stops working.
This server had a lot of VM creation and deletion, so the virtual network of the host may be somehow corrupted, but i can't delete it and recreate it as far as there are others working VM that i really can't afford to stop. If i knew it would solve the issue i would do it.
Any Advice?
