Yes, both under local admin and domain admin logins. I can get the converter agent installed on the source machine when I start the convert server wizard, but after the agent installs, it is unable to get system details, which is where I get the access denied.
Like I said, I have a network with significant security settings in place, so I would be surprised if that was the issue. What I can't figure out, is what sort of permissions converter server, or agent, needs to to have permissions to work.
