Windows Server 2012 Essentials Upgrade receives error code: 80072EE2 - Step by step with screenshots

Q: We are running Windows Server 2012 Essentials as VM on A Windows Server 2012 host. When attempting to run Windows Update, we get this error code: 80072EE2. How can we fix it?

Case 1: We fixed the problem by disabling all offloading on both physical and virtual NIC.

Case 2: If you migrate SBS to Windows Server 2012 Essentials, you may have this issue. The Windows 2012 Essentials server may try to connect to the old WSUS server (The SBS2008 server) to verify the update information. Normally, after migrating to the Windows 2012 Essentials domain, we will demote the old SBS2008 server in the new domain, so the Windows 2012 Essentials failed to get the update from the old SBS2008 server, and then we got the error message “0x80072ee2”.

You may try the following steps to fix the issue:

1. Open the “Group Policy Management” console on the Windows 2012 Essentials server.

2. Expand “Domains”, expand “<domain.local>”, and then expand “Group Policy Objects”.

3. Please check if the following GPOs are existing:

Update Services Client Computers Policy

Update Services Common Settings Policy

Update services Server Computers Policy

Windows SBS Client – Windows Vista Policy

Windows SBS Client – Windows XP Policy

Windows SBS Client Policy

Windows SBS CSE Policy

Windows SBS User Policy

If yes, please delete the GPOs above, then run the “gpupdate /force” command on the Windows 2012 Essentials server, and then please reboot the Windows 2012 Essentials server.

After that, please check if we can run the Windows Update on the Windows 2012 Essentials server successfully.
