SCCM 2012 Low Bandwidth WAN

In my test lab I have started to test  SCCM 2012 over a low bandwidth (512k Down/256k UP) WAN (using my home brewed WAN emulator) our international offices. I have placed a Distribution point at each location and am deploying updates from our main site through the DP. I have set the Primary site to only use 10% of bandwidth during business hours and 100% after business hours. Of course I have set a separate boundary group for each site based on the AD sites and IP address.

Things I found so far:

Uprade SCCM 2012 to SP1 Beta

So today I started to play with System Center Configuration Manager 2012 SP1 Beta. What I found nice for this SP from others for the System Center 2012 suite was that I was able to install it on Windows Server 2008 R2.  So far all the others required Windows 2012 RTM. I had previously installed SCCM 2012 using SQL 2012. I was able to do that here as well but it required CU 2, however CU 3 has been released so I used it. It can be found at: Like wise WSUS 3.0 SP2 requires KB2734608 found at:

SCCM 2012 Drivers

Boot images are used for booting into a graphical interface for imaging and capture. PE is based on Windows and lets face it, Windows needs drivers and some devices like storage controllers and network controllers are critical for operation. Without these drivers your PE boot image cannot  access the hard drive or network controller. If you are doing a network boot, access to the network controller is very important. like wise nothing will work if PE cannot access the hard drive.

Lab: Building WAN Emulator experiment

Building a WAN Emulator

With the need for a WAN emulator that could simulate Poor connections over VSat, ADSL, and other types of connection available in developing areas I set out to see what was available. There are hardware solutions out there. We already had a network Wan emulator appliance but it is limited to one network at a time, with 3 Ethernet ports, 1 management, 1 LAN A, 1 LAN B. We needed more.
