When opening MYOB Accountants Office (AO) Tax from AO Practice Manager in a Terminal Server environment, you may experience the error "Machine Name not Unique".

Each workstation using System Services must be identified by its own unique machine name. When System Services detects that the machine name is already in use, it triggers the above error. For example, when all users log onto the same Terminal Server.

You can resolve this error by following the three steps. This will allow System Services to identify users by their windows username instead of their machine name.

Prior to commencing these steps, we recommend that you have file extensions turned on. Step-by-step instructions are available in Viewing hidden files, folders and drives or enabling file extensions in Windows.
