PS/DP/MP task sequences
I get so many customers asking me this question: How can we deploy X amount of DPs/MPs or Primary Servers via a task sequence?
May I suggest a custom task sequence which builds out the above server and has a final step which adds the necessary roles without having to show the sccm site server install credentials?
This way the CM cmdlets can be invoked via the step - all that is needed are the parameters for the server.
if you have to do this manually for 800 DPs it would be simply adding all the server machine names to a collection and the task sequence will take care of the job.
