Problems with net booting from the server

[djsmiler]

We have a mac server which is all set up and running.

Some machines can net boot to it to enable me to re image them with the net boot image stored on the server.

Other machines which are the same type and hardware as the ones that have been imaged are not getting a connection from the server.

When i hold the N key down to boot from the server i get the spinning globe then the machine eventually restarts after a while with the log on screen from the previous build.

 

Not sure how to get around this.

Have you got multiple vLANs at all?
