I'm trying to test the ZEN Migration Utility. I ran ZENMigration.exe. AdminStudio is asking for the server URL and the user name and password. The server name is testo so I'm putting http://testo in the server URL field and the proper user name and password. I know the user name and password are correct because I use them to login to ZCC. Also DNS is workng properly. When I click on Login it says "Login Failed"
