Recently with an In-Place on an Lync 2013 Edge server on the installing roles stage it failed ! what!
I believe from finding this error and finding the resolution it was caused because after starting the in place upgrade and after the prerequisites checks are completed by the installer i had then opened the NIC properties to check DNS servers and left it open during the upgrade.
I did test this afterwards in a lab and at the prerequisites checks it flagged this up and stopped the upgrade but it doesn’t stop you opening nic properties after the pre req checks are completed.
So a lesson here with in place I’m adopting is close everything you may have open including Management shells etc and only leave the in place upgrade setup open as it does more under the hood than you know 🙂 that’s a personal perquisite check I’m adding to in place upgrades I’m adopting now 🙂
Here details on the error.
I had an error message Error encountered: HostLocalActivateTask execution failed on an unrecoverable error.
From reading local edge server event viewer i noticed there was an error saying please uninstall Lync Media relay driver from the NIC. I did in fast find the Lync Server Media Relay Driver it was mentioning.
I uninstalled this from the NIC and retried the setup.exe and it completed successfully 🙂
