I need to create the same 60 user profiles on 30 pcs with Windows 7. They will connect to a windows server 2012. Is there a fast way to deploy profiles on all the computers quickly? First step would be of course creating users and rights in Windows server. Then?
I'm not certain that's particularly necessary, nor are roaming profiles, really depending on what exactly you want.
If you simply want 60 people to be able to log into any computer, then create a domain (you didn't technically say whether there was one already or not), add the 30 PCs to the domain, setup AD, give the users AD accounts, and do it that way.
If you want their full profile data (AppData, etc.) to follow them from PC to PC, then you will need to use roaming profiles.
If you only want their files accessible from each computer, give them a network share folder of their own and set group policy to auto-map it or add it to their AD profile, setting folder permissions appropriately.
A little more context and details about what the exact requirements and goals are would help give you a more precise answer.
