An unedited ipconfig /all
of working / non-working may help.
No network access for one VM (6 running fine). Hyper-V
I have a Hyper-v environment that have been fully functional for years.
As of yesterday my file server no longer can access our network. No network access.
I can reach it through our hyperv servers and have tried restarted it and resetting ever since.
I have 6 more VMs that connects without problem.
The VM is server 2019. Hyper-V servers are 2012.
I have one more 2019 server and the only difference in network setup is the driver of the NIC.
Microsoft Hyper-V Network Adapter - 10.0.17763.2145 (driver date 2006-06-21) not working
Microsoft Hyper-V Network Adapter - 10.0.17763.1577 (driver date 2006-06-21) which is working.
I find it hard to believe that this driver is causing the problem but it is the only difference I have noticed.
Tried both static and dynamic IP for the server, no luck.
I have deleted and added the network adapter several times.
I have deleted one of the virtual switch and added a new one. tried the new switch with other VM and it works.
but my file server still has no network access.
Any thoughts?
