Hyper-V Windows Update would stop working with error 80072ee2
After building a Windows 2008 R1 VM Windows Update stopped working.
Windows Update Installed the latest update for Windows Update then any further attempts to check for updates resulted in a 80072ee2 error.
It was still possible to browse the web.
A temp fix was to use the Legacy NIC on the virtual machine and windows updates started working again.
Just built a Windows 2008 R2 VM with the same problem but tracked it down to a setting on the VM NIC. The specific property Large Send Offload Version 2 (IPv4) must be set to Disabled and Windows updates starts working.
How It’s done:
Open Local Area Connection properties
Select Configure
Select the Advanced tab
You are looking for a property Send Offload IPv4
Disable this property and Windows Updates should start working again
Disabled this on the Windows 2008 R1 server with similar results.
Thank you so much for this post. Spent a couple of hours trouble"shooting" before stumbling upon this.
