FDqM: Unable to create Load Balance Manager object!

During some testing in FRqM I came across some strange errors:

"Unable to create Load Balance Manager object!
Please verify that the user name, password, and domain are correct
Error=Cannot create ActiveX component."

 

We did check the username and password for the DCOM user and all is okay, but somehow it did not make the relation between FDqM and the DCOM user.

We did the following to solve this issue:

• Start the ‘dcomcnfg’ tool in Windows
• Expand Component Services\Computers\My Computer\Dcom-Config and locate the following object: {E652643D-6CC1-48AC-915D-01842B04F29} 
• Right-click and choose "Properties" and click on the "Security" tab
• Click the "Edit" button and remove all users except the default: "Everyone" and "System" and click OK, then set the radio button to "Use Default"
• Click the "Edit" button under Access Permissions and remove all users/groups except the default items and click OK, and set the radio button to "Use Default"
• Now click the "Identity" tab and remove the ID in the "This User" field and set the radio button to "The Launching User" and click "Apply" and "OK"
• Now try to launch the FDM Load Balance Config and all the extra tools for FDqM.
