Remote Desktop Gateway Port. On your RD Connection Broker use powershell commands below to change the published gateway to include your custom port:
In case you are using also published Remote Web Apps you have to use a powershell trick to change the TCP port to your custom. Now, when accessing with the RDP client you have to specify the RD Gateway server name with the custom port you have to specified before. Modify the HTTP and/or UDP port number and click OK.Right-click the Remote Desktop Gateway server name and select Properties.
Open Remote Desktop Gateway Manager (Start > Administrative Tools > Remote Desktop Services): In that case you should change the port 443 to something else. Many times you are limited to one public IP address and the port 443 is already occupied by some other service. A work-around is to have other services relying on TCP (such as Kerberos with the proper registry entry), but a better work-around is to have the WMI process isolated for this consumption.The default Remote Desktop (RD) Gateway encapsulates RDP in HTTPS packets listens on port 443 (for TCP) and port 3391 (for UDP).

But how come that the WMI subsystem eats all those ports? The clue is not on the machine but in the domain.Īccording to the Microsoft Premier Support, there is a bug under Windows 2016: when applying WMI Filtered GPOs, UDP Ports are not released enough by the Policy provider when using the WMIPRVSE process. Both can print locally to the HP just fine, over the wifi. They both have one HP network printer, same printer over wifi, and the one has a Star receipt printer. If you are able to force Kerberos over TCP before the next issue, you would see that you don’t have trouble to connect, but that the UDP port exhaustion is still present. They are on their own remote network, outside of the network where the Windows Server 2016 is at. The message (Source: TCPIP, event 4266) you get before the DNS issues is “A request to allocate an ephemeral port number from the global UDP port space has failed due to all such ports being in use”. If you restart the machine everything is of course cleared up. If you issue an netstat -a -b -n command, you’ll see they are all eaten up by the WMIPrvSe.exe process. If you look carefully at the event viewer, you’ll see however an error from the TCP/IP stack, saying that there is no UDP Ports left. “The system failed to register host (A or AAAA) resource records (RRs) for network adapter” On the machine, you are likely to encounter the event 8015 of source DNS Client Events. However if you troubleshoot the connectivity between the Domain Controller/DNS Server and your machine, you see no error in the firewall, just that the DNS Service isn’t answering, whereas other clients don’t have any issue. The GPO client side fails to be applied because no Domain Controller is to be found. When you investigate further you notice warning and errors for the DNS Client service stating it could not register the server. When you manage to connect to the host, using the console or a Powershell session, you immediately check the time and you see no discrepancy between that machine and the one you’re connecting from. Whether you need a Windows Server 2012 Remote Desktop Services 1-user CAL or a Windows Server 2016 20-User RDS CAL, you’ll receive delivery within 30 minutes during business hours when you order from us. When connecting using RDP to a Windows 2016 server, you may receive an error message which seems clueless to you: Windows 2016 Remote Desktop cannot verify the identity of the remote computer because there is a time or date difference between your computer and the remote computer. The guide also looks at why remote desktop CALs might be needed in addition to regular local access licenses.
