Hello, I am just starting to setup our PPA environment. We currently have four Plesk 10.4.4 and 11.0 servers. To start, I did a new install of Windows Server 2012. I then went to my PPA panel, went to Infrastructure>Service Node>Add New Node>IIS Web Server. I then enter the IP address of the server, and the admin user/pass. I then get an error saying Error User Credentials being provided are incorrect. (Response Code is 26). However, the credentials I provided are for the administrator account and I confirmed this multiple times. I even created a snapshot of this machine and installed Plesk Panel 11, thinking that had to be done, but the same error occurred. I have confirmed that the IIS machine has iNet access. I have turned off the windows firewall on this machine as well. Still no success. I also disabled UAC. Can someone shed some light on what I might be missing? Thanks.
