Strange RDP issue - MultiSite environment

Question

Hi Guys,

I'm running with strange issue , following are the details:

Total number of sites, A, B, C, D

RDP between A, B, C is working fine without any issues

Couple of weeks back RDP from any site via hostname was not working to Any of site D servers.

After rebooting the servers and changing Hyper-V Virtual Machine Queues (VMQ) service, setting TLS to 1.2 across.

I manage to bring two servers but still some servers including couple of Physical servers have no relation with Hyper-V changes are facing RDP issues.

RDP via local creds when remoted from other sites working, RDP via IP from any sites is working

RDP via hostname to the same site working but not from other sites.

It seems AD issue to me as DNS seems to be working as expected

Appreciate if someone can help.

Hi,

I'd be happy to help you out with your question. Sorry for the inconvenience caused.

There could be a few different causes for this issue.

Firstly, it's important to check that DNS resolution is working correctly. Ensure that your DNS servers are properly configured and that they are resolving the hostnames of the servers in Site D correctly. You can use the nslookup command to check this.

Another possible cause for your issue could be related to Active Directory replication. Check the event logs on the domain controllers in Site D to ensure that there are no replication errors.

Please check the firewall settings on the servers in Site D. Ensure that they are configured to allow RDP traffic from other sites. You can use the telnet command to check if the RDP port (default 3389) is open and reachable.

If none of the above suggestions help, please look at group policy settings on the servers in Site D to ensure that they allow RDP connections from other sites. Additionally, ensure that there are no network connectivity issues between the different sites by checking the routing tables on the routers and switches.

If you have any other questions or need assistance with anything, please don't hesitate to let me know. I'm here to help.
