WSUS doesn't like its IP address changing!

[Sheridan]

After setting up SUS on a 2016 server (I know, I'm a sucker for punishment!) I realised that it was still dhcp, so I set the lan card to a fixed IP.

 

Oh Oh, bad idea, WSUS is now broken! It can't synchronize any more and after much searching around it seems a full uninstall and reinstall of wsus is required. You can really tell 2016 server is based on W10!

 

So beware changing ip or lan card after wsus install, it breaks it!

Actually - correction, once you do this WSUS is completely broken, even uninstalling it and reinstalling doesn't work. Only a reinstall of the server! Otherwise you will get stuck on the http error!

 

Time to bin WSUS and just use home updating methods I think

Could you not have just changed the DHCP Lease to a reservation for your WSUS server?

Have you checked IIS hasn't bound to the old IP and you need to manually point it to the new one?

Changing up back to what it was didn't fix the problem, it really screwed up Wsus! In the end I did a reinstall on the new IP address.
