Set static ip for Hyper-V Server 2016 virtual ethernet adapter.
-
So currenty the Hyper-V host has 3 Virtual ethernet adapters set to get their ip via dhcp. I am trying to change them to static, but when trying I get this error:
C:\Windows\System32\en-US\sconfig.vbs(726, 21) SWbemObjectEx: Invalid indexAfter the error appears the interface defaults to an APIPA address, I have to set the interface to dhcp to get it working again.
This is the results from
Get-NetAdapterBinding
Why can't I set the interface to static and why does it only work for dhcp?

@romo You have ipv6 turned off according to someone earlier today.
-
@momurda I saw the post before but since the error message differed I had not tried enabling ipv6.
Solution error:C:\Windows\system32\en-US\sconfig.vbs (696, 21) SWbemObjectEx: Invalid index-696
My Error:C:\Windows\System32\en-US\sconfig.vbs(726, 21) SWbemObjectEx: Invalid index-726I just tried it and get the same error sadly =(:
ms_tcpip6- True
error

How did you break
sconfig? -
Already tried changing the IP address using Windows Admin Center?

Probably faster to reinstall the host then import the VMs.

@jaredbusch Really don't know what they did. We figured out the host was using DHCP because after an outage some VMS were not coming back up and we had to remote in.
Tried connecting via the dns name, just to find out the static dns entry does not work because the server had been setup to use dhcp without even a reservation.
So we are trying to set the Hyper V host to have a static ip and here we are.

Did you reinstall the host OS yet? Takes only a few minutes, and then a few minutes to reconfigure the host settings, then a few minutes to import the existing VMs...

Not even remotely feasible in this environment. They don't have any swing space to do anything of the sort. Nor can they be taken offline mid day. It just wasn't built for that kind of flexibility.

No swing space needed, so long as the OS is it's own partition, typically the C drive, where all the VMs live on the D drive. You pop in the USB stick, and reinstall the OS. Once back, you right-click in Hyper-V Manager and import the VMs that are still there in the D drive. You don't format that D volume when you reinstall, only C. YOu leave D alone so it's there when it's back up.
It shouldn't take more than 30 minutes total, easily done end of day or after hours. Or, bring up another Hyper-V host to live-migrate to (if you have the space) to prevent any down time.
There are a lot of options rather than spending weeks figuring out such a dumb issue.

You pop in the USB stick,
Already a problem, no local tech. Can't ask the site to do something like that unless there is a full blown outage underway.

Having to bring in a local tech or get a swing machine are actually much more intensive than looking at it remotely for a while. But seems doubtful that it will take weeks. Only has had a few minutes of being looked at, and only today.

iDRAC/iLO/etc, USB stick not needed if that's available. I was just giving an example case, not an exclusive item.

Oh, didn't realize it was like that. No local IT, no other available infrastructure or anything kind of limits things a lot.

Yeah, a LOT. If we were local and it was one of two (or more) machines, yeah, we'd happily reinstall. As it is, we are scared of the backup device failing. Which isn't terrible as it is ONLY a backup device. But taking the server offline... we are pretty dependent on it.
