I can see that my ECP virtual directory is setup correctly

Get-EcpVirtualDirectory -ShowMailboxVirtualDirectories | FL Identity,*Site*,*URL*,*Auth*

So the most common advice out there is to removeethe virtual directories, and recreate them, but when I attempt to remove them I get the error;

The operation couldn’t be performed because object ‘EX-SERVER-NAME\owa <Default Web Site>’ couldn’t be found on
DC-NAME.pnl.com’.

There are some posts that suggest (I simply re-sync my Exchange to my Domain Controller). But I’m not really sure how thats possible, (without a reinstall?). If someone would like to post below an alternative solution I’d be happy to publish it?

This is how I end up fixing it every time, which impractical because it involves downtime! Download the latest Cumulative update, mount the the CD image, and run;

F:/Setup /Mode:upgrade /IAcceptExchangeServerLicenseTerms

YES I ACCEPT: That’s like using a sack of sledgehammers to crack a nut, but it works. As I’ve pointed out above, I’m happy to publish a more elegant solution, if someone posts one below.
