Windows 2008 R2 Hyper-V windows update error 80072EE2 and losing network connection
On a Windows 2008 R2 Hyper-V configuration with 2 network adapters I experienced the following problem: I installed a Windows 2008 R2 guest this was no problem, but when I try to do windows updates I got an “Windows could not search for new updates, An error occurred while checking for new updates for your computer. Error(s) found: Code 80072EE2” error message.
Everthing else looks fine, dns resolving works fine, network browsing looks good, I could access internet pages even the windows update page, but trying to update gives this particulary error.
Tried the same on a windows 2003 guest and everything looks fine. Installed another Windows 2008 R2 server same problem occurres.
Solution: After some more trouble shooting I found that when I start the windows update I lost network connection on that particulary network adapter, even on all other VM’s using that adapter and on the Host. Now I was connected with the other adapter so I didn’t see this behaviour in first place. So I bound the other network adapter to one of the Windows 2008 R2 guests and I could windows update with no error.
Because I would like to know what was causing this problem I found after some more troubleshooting and testing that the problem was caused by the Large send Offload setting enabled on the network adapter. After disabling this setting everything works fine.
The network adapter was causing the trouble was a D-Link DGE-528T Gigabit Ethernet Adapter.

what a good catch!!! Thanks
Hello, excellent work!
I have the same problem with the network card settings but this problem is in hyper-v server core and I don´t know like to change the advanced settings
Do you know how to change the NIC settings in this scenario?
Thanks for your help
Hi,
sorry to say I don’t know how this works within a Server core solution never used that before, but maybe someone else has and can help.
Otherwise you might post your question in one of the appropiate Technet Forums, there are a lot of helping people that might have a solution for you.
For Server Core, please look at this:

I had exact the same issue with Citrix Xenserver V 6.0.2.
Your solution helped me out!
Thank you so much!
You da Man! Thanks a million, we’re on the road to updates now…
This solved as well my problem with a 80072EFE problem on Windows 7 while doing Windows Updates. Thanks a million!
Thank You!!!
This article helped me a lot!
I had this issue as well but the fix didn’t solve it for me. Clicking the “Install updates” button actually had the server looking at an old WSUS server it was still pointed to instead of the internet (though there was no indication of this in the error). Clicking on “Check online for updates from Microsoft Updates” instead of the “Install Updates” button pointed it towards the website which worked.

Thanks, same issue in ESXi 5.1 with e1000 and vmxnet3 adapters. After disabling offload, everything OK.
Excellent thanks! Same problem with the same NIC!!
Awesome! That was a hard catch!

How did you figure this out?
You are a Prince among men! Good fix.

This valid for all 80* errors with windows update. Thanks a lot..
Thank you so much!
I had Windows Update error 8024401C on a Windows Server 2012 R2 client running on a 2008 R2 host. All other web traffic worked fine which made it very confusing. Altered this setting on the client and problem solved.
The host NIC in this case was a Realtek PCI GBE Family Controller (RTL8167).
