Windows Server 2008 R2 Core - Poking at the Firewall: Part 2

Despite my efforts, I have not yet found a way to use the "Server Manager" MMC snap-in to connect to a Server Core server (maybe it is too complex) ... but RDP, and other MMC snap-ins like Firewall management, DHCP, DNS, etc ... they are all available.

From http://technet.microsoft.com/en-us/library/ee441255(WS.10).aspx

"1.On the server running a Server Core installation, type the following command at a command prompt:

cscript C:\Windows\System32\Scregedit.wsf /ar 0

This enables the Remote Desktop for Administration mode to accept connections.
"


and

"To allow all MMC snap-ins to connect, at a command prompt, type:

Netsh advfirewall firewall set rule group=“remote administration” new enable=yes

WuInstall - Command Line tool for WU Client

WuInstall 1.1 is a free command line tool (with a license for unlimited commercial & non-commercial use) for managing Windows Update clients a bit more effecively that the basic client provided by Microsoft.

It is written in C++ & uses the Windows Update API.

The three main commands /search /download & /install along with /reboot /shutdown /match & /criteria allow for a much more precise and informed method of managing updates via the command line.
