Error when connecting as Local Administrator via RDP

Hello,

Do you encounter the same issue in external mode?

Best regards,

Yes, same error in external mode.

Hello,

In external mode, we use Microsoft RDP, which is external to RDM.

If you click on Start \ Run and type mstsc.exe, are you able to establish the communication using this program?

Best regards,

Same error running Microsoft RDP

Hello,

Since it's not working outside RDM, this is why it's not working in RDM.

I don't know if this would help, but here's some links that you can consult

Hello,

I realize it's an old thread but I have exactly the same problem and are able to connect using mstsc.exe directly to the server.

The server is a Windows 2019 Standard (backup) server which is not joined to a domain for security reasons.
If I connect using mstsc /admin /v:<ip> no problem. If I connect using RDM and the same ip address and using external mode with the same user account I get the error "A verification error has occurred (Code: 0x80004005)".

If I disable on the server that NLA is required I'm able to connect from RDM. But cleary I don't want to disable NLA.

Any suggestions are welcome.

Best regards,

Onno

@onno01,

What version of RDM are you running?

Could you post a screenshot of the error message please?

Have you tried to create a functionnal .rdp file and import this file in RDM and launch it?

Best regards,

Hi Jeff,

Version is 2019.1.41.0 64-bit. I attached the error message.

I tried importing a functional .rdp as you suggested and that worked. In the Connection part of the session settings I see now that Activate network authentication NLA is disabled in RDM, when on the server NLA is required, but it works anyway.

Thank you for your help!
