Remote Desktop Connection Manager on server with Duo - "Ordinal not found"

[gmtexx]

We installed Microsoft’s Remote Desktop Connection Manager on a terminal server with Duo authentication installed so we can RDP into other servers from that box. Everything worked great until we rebooted the server, and now every time we try to make an RDP connection to another server using RDCMan, we get this error message multiple times:

“The ordinal 379 could not be located in the dynamic link library C:\Program Files\Duo Security\WindowsLogon\DuoCredProv.dll”

If you click through the multiple warnings RDCMan connects to the remote server,

Anyone seen this before? Any way to resolve it?

Thanks.

On 2 August DUO was new release and I don’t see any fix for this issue.
PatrickKnight - could you comment this?

Hey y’all, we’ve have an early release available that resolves the “Ordinal not found” issue. For anyone interested in getting access to that before the General Availability release, please send me a message on here and I can get that to you.

Thanks!

I’m interested.

Thanks,

Hey everyone,

This fix is going live tomorrow, you’ll be able to find it here ://duo.com/docs/checksums#duo-windows-logon for when it gets released.

Hi everyone,

Today Microsoft announced the deprecation of Remote Desktop Connection Manager (RDCMan) following the discovery of a security vulnerability that will not be fixed in the application. We recommend that you read the announcement here and discontinue use of this tool. You’ll find more info about this on Microsoft’s website.

Thank you.
