New releases: OS deployment feature pack for SMS 2003, more online training for MOM 2005
The operating system deployment feature pack for SMS 2003 SP1 does just what you'd hope - allow you to create and deploy Windows OS images to lots of client machines, with unattended imaging, backup and restore of user state, and all the replication and targeting features of regular SMS 2003. Grab a copy of the beta from the SMS 2003 OSD site.
The SMS team have also published a white paper on how to use SMS 2003 in a corporate environment with lots of roaming client computers and intermittent network connectivity. This is not for the weak: Configuration and Operation of Advanced Client Roaming.
Finally, the MOM 2005 online training courses were too popular - so they're adding more servers and running more courses. If you couldn't sign up last time, give it another try.
