Hey everyone, I'm stuck trying to figure out an issue with remote access in my closed lab environment. I've got a few Windows 11 Enterprise workstations and two Windows 11 Pro workstations, which I'll refer to as Ugly1 and Ugly2. Both Pro machines were supplied by a vendor, and I can't reimage them since I don't have the installation software for their tasks. They're all joined to the same domain and are in the same organizational unit without filtering.
Here's where I'm having trouble: I can access Ugly1 and Ugly2 from the Enterprise workstations and the 2019 servers with no issues. However, I can't remotely connect to Ugly1 from Ugly2, or vice versa, via RDP, UNC, or computer management. Additionally, a mapped drive script that should run at logon fails when it tries to access shared folders on the other Ugly machine. I've checked permissions and tried rejoining one of the machines to the domain without any change. What am I missing?

Have you checked the DNS settings? It's essential for both machines to be properly registered in the DNS server, especially in an AD environment. Sometimes, connectivity issues between machines can be traced back to DNS problems.
Can you access other network resources from Ugly1 or Ugly2? If so, it may be a specific issue between them rather than the entire network.
What's happening when you try to connect? Any specific error messages? Also, make sure they can ping each other. If pings work but you can't connect via RDP or UNC, check the Local Security Policy to ensure that both machines are allowed remote access.
