RDP Problem w/ Credentials

avatar

Hi ..

I am having a weird problem that I've never had before.
I am trying to connect to a set of machines with RDP for a project and I created some sessions.
I did everything as normal (no special changes, the default RDP session type) and I only added the hostname & the user/password via a Credential item.

Strange thing hapens when I connect to the server, it takes my username/domain but it prompts for a password on the RDP session (not a pop-up at connection).

Now I use a generated password for my account, which means typing it is a real PITA; hence why RDM to save the day (normally).

It's only happening one some machines, not all, which is why I don't think it's the session I created.
And I am wondering if it's something in the way RDM passes the creds to the RDP protocol that the password isn't getting there for some reason.

Can someone help ?

Hello

Is there something specifically common about the remote machines where you have this problem? It sounds like NLA might not be enabled, which it is by default on any modern Windows OS. What's the server operating system?

Thanks and kind regards,

I can't see anything 'common' about them.

I tried disabling the NLA on the session and it had no impact at all.
I even tried different versions of the RDP in the 'Advanced' setting, which also had no effect.

One thing I noticed .. If I set the 'Credentials' to 'None', the Domain\User was still there.
And when I asked the Advanced part of the Session to do User@Domain, it did not do it.

Could something be blocking the whole process of giving the session creds to the RDP client ?
Could this be a GPO of some sort that is getting in the way ?

Before you ask ..

Version = 2025.1.37.0
SQL Lite as the DataSource

Hello

Interesting; I guess that discussing NLA is a red herring because if NLA is not enforced (which it seems it isn't) and you had incomplete credentials, authentication would fail before you even got to the RDP protocol.

Do you have some saved credentials in the Windows Credential Manager (under "Windows Credentials")? I do believe that a stored credential there might override what RDM is doing.

Kind regards,

Nope. I am looking at the forum and seeing quite a few posts about credentials w/ RDP being odd recently.
I am wondering if I will go back to an earlier build of RDM, see if it works then.

At the moment, I did manage to workaround the issue with a typing macro; just a PITA.

Hello

Yes, try grabbing an older build and let us know if it works in that case.

Something else you can do to test is set the RDP credentials to "Username and Password" and put the credentials directly in the session. Does it work as expected then?

Also, a typing macro is probably overkill for a workaround - in the "Actions" menu you have a shortcut to "Type Username" and "Type Password" - although if the linked credential is the problem, that might have an issue as well. That would also be another interesting thing to try.

Let me know your findings and sorry for the inconvenience.

Kind regards,
