• Patch Lady – Domain admins and issues with KB4489878

    Sandeep pointed out that after he installed KB4489878 on a Server 2008 R2 he can no longer use the netdom query commands.  I can attest that commands on a Server 2012 R2 machine work fine, but on a Server 2008 R2 it comes back with an error.

    That’s what it looks like on a Server 2008 R2 after the March updates when I went to check.

    This is what it looks like on a Server 2012 R2 after the March updates on a patched server.

    Anyone else seeing this?

    netdom /query is a command used by Admins to determine what server is the domain controller, what holds what is called the FSMO roles.

    In on premises deployments it’s a command not used that often, but it’s like the c prompt or command line.  It normally just works and you take it for granted.

    It’s not a deal breaker bug, but needs to be addressed nonetheless.  I’ll keep you posted on the status.

    Now documented in the KB as a known issue.  Microsoft is working on the fix.
