Questions[subscription](server)

I am trying to set up a source initiated event Subscription from a Windows 2019 server to a Windows 10 Client. I know that might sound backwards but I don't really have a choice for a variety of reasons. Both of these devices are domain joined, the server being the DC.

Anyways, I am getting an Error Code 2 "Unable to check the status of the Firewall" when I try to activate the subscription. It also says "The system cannot find the file specified". WinRM throws this error when I do "winrm qc" or "Set-WSManQuickConfig -force". To me this says that WinRM cannot see the firewall.

I have opened port 5895 and this didn't work. I made sure that the Firewall was active on Domain. I made sure the WinRM listeners have IP addresses. Eventually I just added an allow all rule only for it to not work (This is an internet isolated lab environment).

What the hell is going on? I'm ripping my hair out. If anyone could at least point me to some better logs that would be helpful. I already know about

I have a couple of RHEL 7.2 systems, which do not have any online connection - also not through any proxy or satellite. I do have subscriptions which I could attach to the systems as described by RedHat here.

Now, my question is: What is the benefit of doing so? I could still not track the system status online or automatically download any patches. From my understanding, I can manually download any packages from the RHN website as long as I have at least one subscription, correct?

Thanks for any advice!

I have a very strange problem with an Exchange 2010 Edge Transport Server.

The server was correctly subscribed to the Exchange Organization and worked, but then someone removed the subscription from the Hub Transport server. So I went to recreate it, starting by exporting the subscription file from the Edge server:

New-EdgeSubscription -FileName C:\EdgeSub.xml

And then I got this error:

New-EdgeSubscription : You can't use the FileName parameter when running this command inside your Exchange organization.

But this is an Edge server, and the Organization isn't talking to it anymore. And, of course, it isn't joined to any domain.

How can I force it to understand it's not part of any organization and recreate the subscription succesfully?

Specifically I'm trying to get a better understanding of Exchange Web Services (EWS) and I see many references to EWS subscriptions. It appears that a 'subscription' is a generic HTTP concept but I haven't had much success searching 'subscriptions' online.

We recently bought a handful of MSDN subscriptions. Should we have received one MSDN account per subscription? Or must all of our subscriptions be managed through a single account?

(In case you're curious about why we can't just examine whatever we received from Microsoft, the problem is that engineering and IT have a very antagonistic relationship around here.)
