Hi, I am deploying Windows 7 across the network. I am auto joining the computer to the domain, so I do not want a local account to be created. I have tried the suggested settings and it did not work: https://technet.microsoft.com/en-us/library/cc732729(v=ws.10).aspx Thanks Jonny I have answered my own question. Following the instructions above does work, however you have to specify login details in the 'Credentials' section located in the unattendjoin properties. Doing this in an enterprise environment is dangerous as the password in this section is not encrypted. I have made another topic to see if this can be achieved. http://www.msfn.org/board/topic/173617-encrypt-unattend-join-password/ Thanks for all your help.
