"Couldn’t create PingPlotter Object" error with PingPlotter Pro Web Interface using IIS

Question

I'm trying to get the PingPlotter Pro Web Interface to work with IIS, and I'm getting this error: 'The call to Server.CreateObject failed while checking permissions. Access is denied to this object'. What do I do fix this?

Solution

You need to grant rights to the web server user to launch PingPlotter Pro, and to create the PingPlotter Pro object. To do this:

• Run dcomcnfg (Start -> Run, type 'dcomcnfg')
• Go through 'Console Root', Components Services, My Computer, DCOM Config, PingPlotter - right click on 'Properties'.
  
• Go to the 'Security' tab and customize all launch and access permissions - put 'Everyone' for full rights on both sections.
• Test the web interface again.
• If this works, then you can back off the rights a bit. Most people have success granting the user that IIS is running (IUSR_{MACHINE NAME}) as, 'Launch and Activation Permissions:' 'Local Activation' only. If this doesn't work, then contact our support department with the details of your error and environment.

We talk about some of this a bit more in the PingPlotter Pro product manual.
