Remote Desktop does not communicate

Question

Hello,

I have several Servers I could not reach using RDP.

• I tried with and without using a jump box.
• The Windows Firewall is OFF
• The network firewall is opened as the flow is complete when checking it... The Network team has checked and rechecked...
• The Credentials are working, as when using the vCenter to Log to the server it works...

Any idea?
Thanks,

Dom

Answer 1

Might try from PowerShell from both source and target. (use target address in both cases)

Test-NetConnection -ComputerName "192.168.49.142" -CommonTCPPort "RDP" -InformationLevel "Detailed"  

Answer 2

Hello,

The issue was with a certificate expired...
Under mmc > certificates > Computer > Remote Desktop > Certificates

Thanks,
Dom
