1E - Nomad, creating Pre-cache command file

While working on a project, I needed to cache a set of files but I didn't want to run the standard pre-cache process on multiple packages for a single or multiple machines and wait the standard time.


Step in PowerShell and the SMSNomad command.  SMSNomad is used to call for the package download and can be executed manually.  The command can be run on outside of SCCM and this was important when you have machines in different forests and you want them to have the same cache files before the forests merge. 


Syntax:
SMSNomad.exe
s   : Run in standalone mode (we don't rely on SCCM to do anything)
p: Package Path
ver: package version as seen in the console


Since I use custom ports my example will include that.  For the default ports of 80 or 443, leave it blank


Here is an example of the command we need to run:


"C:\Program Files\1E\NomadBranch\SMSNomad.exe" --s --pp="http://Server.Foo.com:132/SMS_DP_SMSPKG$/AB100002"  --prestage --ver=16


[Download the Configuration Manager package from site AB1, source version 16]


Let's get to the heart of what I was doing ;)


There are two parts, the first part pulls all the packages from a Task Sequence, the next pull all the Packages with a given name in the title and then pull Applications.

1E Nomad / Active Efficiency, Groups Subnets for Single Site Download

If you are using Nomad 5.x / 6.x and Active Efficiently then hopefully you are utilizing the Single Site Download (SSD) feature.  This allows all machines in a given site to share content more efficiently, thus improving the experience.


Example:
Machine (computer1) is in an AD boundary call BOSTON.  This machine is in Subnet A
Machine (computer2) is in an AD boundary call BOSTON.  This machine is in Subnet B
 
Without SSD one machine from each subnet would pull from the local DP/Secondary.  With SSD enabled a machine would have the ability to jump from Subnet A to Subnet B for files instead of reaching over to the DP. 


The default script create the groups via AD Sites and Services
What if you have several AD sites that should be grouped. 
Suppose you have an AD Site called "Boston-1st-Floor" and Boston-2nd-Floor" they are separate AD sites but they are still talking to the same DP.  Here is how you can force the group to create as the PowerShell script is running.


Note that I am ignoring the IPRange boundary types.  This is because for us the IPRanges are use via the VPN solution so we ignore them.


The IPSubnet display name for us is normally like 'XXXXXX - (127.0.0.0./30) ' So for us we simply read the name in SCCM and pull the IP address
