PENDING Upgrading SCCM 2010 to 2203 unsupported site server operating system

[TimCollard]

Hello,
Attempting to upgrade SCCM via the Updates and Servicing results in the following failure.
The site server is 2019 - patched. The URL in the description is not helpful.
Any help is much appreciated.
TIA
Tim

Unless this is a single site server, you need to review every single server with a CM role on it. It is easier to review the log to see exactly which server it is flagging with problems.

Thanks @Garth.
The logs are pointing to an issue with the netbios name issue on our SQL Cluster.
Thinking the issue may be WINS - I have implemented binding as per https://docs.microsoft.com/en-us/tr...s-wins-dont-bind-cluster-ip-address-resources, however the logs are still showing the same failure.

Any help is much appreciated.
