Hi everyone.
I have a Windows Server 2022 VM (through proxmox) running as a DC, and DNS and DHCP server.
However, within the last week, it no longer sees any computers, except for itself, tsclient (as expected), and a non-domain computer, but just one non-domain computer. It is one of many that are configured the same, but it is the only one that is seen by the DC.
I have a few other VMs on the same physical machine, all of which face the same problem.
Other standalone PCs running Windows Server 2022 also have the same problem.
I have followed this link, enabling what needed to be, which allowed everything but computers to be shown on the network — TVs, routers ecetera, but not computers.
I have seen that VPNs can sometimes influence this, as I've seen others with similar issues, and within the last week, I have installed OpenVPN, but not configured it. However, I did uninstall it. Whether it was the cause or not, the issue has not resolved, and I'm starting to scratch my head as to why.
I've ran a couple of Windows troubleshooters which seem to universally conclude that the target computers exist but are unaccessable, unless it's a remote connection, or from Server Manager. Very helpful I know!
I'm wondering if it is a group policy thing, but even then, I don't know where to start.
Any help is greatly appreciated.
Thanks very much.
