PENDING Remote Control Viewer not working since update to 1906

[Seppic]

So I finally got my SCCM fully updated to the latest 1906 build. Everything appears to be functioning fine except for Remote Control Viewer. It has worked flawlessly ever since our initial setup 3+ years ago. The only change that happened was upgrading SCCM to 1906. The CmRcViewer.log shows:

Address Lookup failed for the target host: 10.0.132.20. No such host is known. (Error: 80072AF9; Source; Windows)

I get this same error connecting via the Assets and Compliance menu clicking directly on any machine, and also trying to manually connect with a host name or direct IP entry. Has anyone else noticed any issues with Remote Control Viewer since the update? That log is from trying to run RCV on the main SCCM server. If I try to run it on a remote machine it gives me:

Failed to open to WMI namespace '\\sccm.mycompany.com\root\sms' (80070005)
Unable to open namespace \\sccm.mycompany.com\root\sms. Permissions on the requested may be configured incorrectly. Access is denied. (Error: 80070005; Source: Windows)

Was there some permission changes as a part of the larger update that I need to address to fix this? I don't see anyone else popping up with a major issue like this. I've tried disabling both the Windows Firewall and stopping our third party AV as well.

Any help appreciated.

Just to provide an update to this. It looks like doing a client "install" where you select to uninstall the old client during the process is fixing this. Is there any insight to why this is happening. Do the clients not update when you update your SCCM infrastructure?

Have you tried to launch the Remote Control session from the Site Server with an account that has full privileges to SCCM?

To upgrade your SCCM clients, you need first promote the Pre-production client (1906 client) and enable automatic upgrade client.

• Promote Pre-production client: https://docs.microsoft.com/en-us/sc...rades#to-promote-the-new-client-to-production
• Configure automatic upgrade client: https://docs.microsoft.com/en-us/sc...-clients-for-windows-computers#bkmk_configure

Just so we're clear. Those two steps are necessary to get the clients on my workstations to auto update?

And yes launching Remote Control sessions with any level of account did not work until I manually updated the client on the machines.

Just so we're clear. Those two steps are necessary to get the clients on my workstations to auto update?

Yes.

You can follow the last step in this guide and make sure that your client has 5.00.8853.1006 version.

Check also if the prerequisites of Remote Control are already done: https://docs.microsoft.com/en-us/sccm/core/clients/manage/remote-control/prerequisites-for-remote-control

Clients settings, permissions...

EDIT: If you have a network firewall between the server where you run the SCCM console and your clients, check if the following ports are allowed: Remote Control Ports

Thank you so much!

So just an update on this. It appeared that this was fixing the issue, and it did for about 60% of the devices in SCCM. We started going a little deeper and running wire shark on the machines that were being affected still. The machines are receiving the appropriate packets from Remote Control Viewer, but just simply never respond. We've tried completely uninstalling the SCCM client on these machine, and doing a fresh push, and still nothing. Tried updating the systems from 1703/1709 to 1809 feature update and still nothing. The only thing we haven't done is a clean OS install, but that seems like a crazy drastic step. I've also ensured all the prerequisites were met. Any other possibilities?

try turning off the Windows Firewall on the client. Like Youssef said, you have to make sure that the clients are on the supported version of your sccm CB version.

if your client and the sccm servers are on different vlans then check your firewall.

@Andrew Ly It is better to make a new post and give us more details (SCCM version etc).
