@aaronstuder said in Windows 7 licenses:

@mike-davis Microsoft Open Programs

For only 4 machines? Also doesn't the open program pretty much mean you're getting audited every 2 years?

@gjacobse The machines are already in production and probably only have a couple more years life in them anyways. Since they are whiteboxes I don't know how much fun I'm going to have finding drivers for the video card, etc.

It's really odd because I have an existing tunnel that has been up for 2 years with no issues on that same SonicWall and it doesn't have the keep alive enabled.

I had a client that was sold four whitebox computers from an "IT guy" that "builds computers on the side". It turns out he installed windows 7 on the machines "with an OEM license from work." Needless to say, my client is buying licenses. It looks like we can only find Windows 10 licenses at this point. It doesn't look like the retail licenses have any downgrade rights. Is there a way to get a legit Windows 7 Product Key so I can avoid upgrading all the machines to Windows 10. Is there an option I'm missing here?

@networknerd said in site to site VPN only works with Keep Alive:

I wonder if Sonicwall Support can explain it?

The reason I was getting this tunnel going is I'm swapping out the current SonicWall that is falling out of support for one that is under support. Once I get the one under support on a live network, I can contact support.

It's really odd. I had a continuous ping going as I was changing settings. At some point I checked the box and all the sudden I started getting replies. I kept checking and unchecking boxes until I found that that was the thing that was doing it. As soon as I turn it off, the connection drops, even though there should be a continuous ping going across the connection.

I was setting up a site to site VPN connection between a couple SonicWalls. (I need content filtering and the SonicWalls were specified in grant money) On other connections where one side might have DHCP on the WAN side, I used Ike with a Preshared Secret and it just worked. On this particular connection, the only way it would work is if we enabled "Keep Alive" on both sides. This involves hard setting the remote IP, so it's not ideal. Can any one tell me what exactly Keep Alive is and what might be a way around using it?

I let them email. Then the ticket system looks for keywords and assigns the category by that, which in turn auto assigns a tech.

What does the windows event log look like? (You said this was a gui install, right?)

My lab server is a GUI install, but the production server is non GUI.

@tim_g Thanks for the commands. If I get the output below, does that mean my NICs don't have the option for VMQ?

Yeah you seem to be fine there. No VMQ.
You could still try updating the firmware to see if that resolves the issue before replacing the NIC.

When I ran the commands in the output above that was on a spare non production server. I ran those commands last night on the problem server and it did have VMQ and it was enabled. I disabled it and it has been up 17 hours now. Before when it was failing, it would go down every 3-5 days, so I'll have to wait a few more days to know if the problem has been licked.

@black3dynamite said in hyper-v bad physical NIC? - vswitch or NIC teaming?:

Which power scheme is active? I've always make sure mine is set to High performance.

High performance. On the host I checked, it's a GUI install, so I went to the nic properties and I can still see Power Management tab and the box for "Allow the computer to turn off this device to save power" is still checked.

When you do: Disable-NetAdapterPowerManagement -Name Ethernet
it removes that tab.

@mike-davis said in hyper-v bad physical NIC? - vswitch or NIC teaming?:

The only other thing I can think of is disabling the power management settings on the NIC, but I'm pretty sure I did that with the:
Disable-NetAdapterPowerManagement -Name Ethernet
command. The command
Get-NetAdapterPowerManagement -Name Ethernet
doesn't seem to show if it has been enabled or disabled, only the Wake on LAN. Does anyone know if there is another command to check the current status?

PS C:\Windows\system32> powercfg /list

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced)
Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance) *
Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver)

That command may work for some stuff on the host, but I tested it on another server and it doesn't change the power settings for the individual NICs. cool command though.

@black3dynamite said in hyper-v bad physical NIC? - vswitch or NIC teaming?:

Its possible Virtual Machine Queue (VMQ) could be causing the issue. Intel or Broadcom?

I'm not sure. I'll have to be onsite to find out. What are the symptoms of that? Would VMQ knock the host offline as well?

Other troubleshooting that I did was cranked up iperf and ran a few GB through it. It didn't drop a beat.

@black3dynamite said in hyper-v bad physical NIC? - vswitch or NIC teaming?:

Is the NIC drivers up to date?

First thing I did was update the firmware for everything and all the drivers.

@coliver said in hyper-v bad physical NIC? - vswitch or NIC teaming?:

I don't know if I would deploy something with known bad hardware into an environment that a tech would have trouble accessing.

I don't want to either. I need to be absolutely sure what exactly is wrong. I shouldn't have said work around in the sense that it would be permanent. More of something like cut it over to the second NIC and make sure it's not a software bug.

@coliver I really want to troubleshoot to see if both NICs are bad, or what the deal is.

@coliver yes. The server is brand new. The issue however is that the server is in a secure environment and remote control isn't allowed. I'm not even sure if a tech can be escorted in. If the work around doesn't work, it might mean picking up a new server or adding a NIC card.
