Windows Sever 2012 running Hyper-V with about 10 virtual machines running for remote access
Quad NIC system (but only using 1 NIC) - static IP and the virtual ethernet (for the hyper-v environment)
Client has Comcast Internet (Deluxe plan which is 50mbps down / 10mbps up)
I have anywhere from 17-22 users internally using the Internet for work. I have 3-4 remote users connected via persistent VPN all day (doing RDP to their remote computer (they hyper-v system)).
On any given day, the Internet will drop it's connection anywhere from 10-60 seconds and come back to life. I know this because I'm monitoring the connection every 5 seconds and I'll get alerts if it goes down.
This is causing issues for my remote users. They will get disconnected and unable to reconnect. Thus far, I only have 2 band-aid solutions I've been using: Have the remote users restart their router and reconnect (this works about 80% of the time, but that's a hassle).
My other "fix" is on my 2012 Server. And I have to reset some of the NIC cards (disable/enable).
When I look at the Network Connections, I see 5 NIC cards: NIC1, 2, 3, 4, and my vEthernet (new virtual switch).
NIC1 is the main NIC with a static IP.
NIC2 says enabled but used with the virtual environment.
NIC3 and 4 (network cable unplugged and I don't use those NICs).
Then I have the vEthernet (New Virtual Switch)
I basically go in and disable NIC2 and the vEthernet. Then I re-enable NIC2 and then the vEthernet (in that order too).
Then my remote users can reconnect.
Why does it do that? Can I use NIC3 or 4 as a fail-over possibly? If so, how? I've experimented with this (drop the connection for 10-20 seconds) and try to RDP into a virtual machine (which is unsuccessful). once I disable/enable the NIC cards, everything works. Why would a 10-60 second outage cause this? And this happens almost daily. Sometimes 2x's a day.
Comcast claims it is because of the Intenet speeds we have - we're maxed out (and the upload speed just can't handle 3-4 remote users and all that overhead with VPN) so they are telling me to upgrade their speeds to something around 100mbps to 150mbps down / 20 up. That could solve the problem, but I'd like to find the root cause before upgrading the entire Internet for the client (unless the speed issue is the bottleneck root cause).
Any thoughts on this? Thanks in advance for your replies.
