How do you force computers to find the new WSUS server?

Do you have active directory in your environment?

If so, you can configure WSUS via  GPO.

You then refresh the policies on your workstations with GPupdate /force.

The computers should then start finding the update server.

How did the old setting get in the registry.  That's *usually* GPO or some sort of script.  If you did it manually and have no method of pushing out the new setting...manual will be the option again.

Try running gpupdate /force on the affected machines.

Yes the WSUS setting are in a GPO.   That is why I am confused that some computers got the new setting and some did not.  The new WSUS server was created and the GPO updated 30 days ago.

My apologies.  The registry setting is correct.  

Is this setting correct?

I don't recommend doing IP addresses. That actually goes against RFC and can cause problems in odd places.   Create an A record and use DNS.

Then, if possible, use https.  8531 is the default.

Otherwise, format and "usual" port, that is correct.

Did the policy apply correctly?

Yes, I ran Gpresult /r and the policy is there.

I will try the FQDN and HTTPS:.   However, we have 2 other locations and they use HTTP:

Note that switching to https *does* require configuration on your part.  I wasn't saying that was an issue. It was a general recommendation.  Security is more important than ever these days.  http and 8530 is fine for testing and getting your setup verified.

ok.  I will leave it at HTTP

Do not know if this is important but I have rebooted and forced update and ran wuauclt /reportnow and wuauclt /detectnow on 3, 64 bit computers and none of them are reporting in.    However, 2, 32 bit compuiters that logged on by the staff did report in.

Thanks

The being patient did not work.   Many of the computers never reported in after weeks of waiting.  We are no longer using WSUS.  We are switching to Automox.   Much better product.
