Hallo, I have set a custom CLS-ID and I have try with several mode to set Domain, username and password, but in my PC it seems impossible to get ready the connection. I Have a W10 pc where I have administrator rights (not fully); I have also try to create a new user, but the error is the same. A little particular is that OPC server run on same PC as nodered works; so I don't think it will use DCOM but just COM and I think there's the issue.... Thanks for help Paolo

Hi Paolo,

Did you ever find a solution to "5 - Access denied. Username and/or password might be wrong"?

I'm also running the OPC/DA server on the same computer as Node-RED.

I'm using "DeviceXplorder" as a temporary OPC/DA server and have confirmed that it is accessible and readable from another OPC DA Client, also running on the same computer:

Node-RED (version v18.17.0 with npm version 9.6.7) is set up as:

I've gotten the "DeviceXplorder" Clsld from here:
