For those that are attending ITForum next week, there will be a couple of Server Core sessions:
304 focuses on remote management via MMC and PowerShell, including firewall configuration to allow these. While 316 focuses on managing from the command line.
There will also be a Q&A session: SRV07- Q&A: Server Core
In addition, there will be a Server Core booth in the Ask the Experts area, where you'll be able to frequently find me. Stop by to say hi and ask me lots of questions!
