When looking in SCCM implementations I regularly bump into the same issues. Lots of task sequences with a lot of different settings in them. Because of the exploding amount of task sequences there is a lot if differiation between them. This blog post describes how to use OSD variables to bring back the amount of sequences.
This example is an school with student’s as well as teachers. They are divided into rooms by using the device collections. Depending on the (class) room they get the software they need.
First we start with creating a device collection for a room:
We are going to set the variables to the collections
– Go to Assets and Compliance, Device Collections, and choose Create Device Collection.
– Give the collection a name like “Classroom 141” and limit the collection to “All Collections”
– Check Use incremental updates for this collection and turn off Schedule a full update on this collection.
– Choose Next, Yes and Finish the collection
Next we are going to set the collection variables
– Get the properties of the newly made collection, go to collection variables and fill in the following variables (depending on your structure)
BSL Students Desktops
OSDOUName OU=R141,OU=Students Desktops,OU=Workstations,DC=students,DC=domain,DC=local
1. Let’s install software based on a variable
Now we can add the variables to the software library
– Go to Software Library, Task Sequences and Edit an task sequence.
– We created a Install CSL Applications (Common Software Layer); this is for software that is scoped on all desktop (like Office, flash, Adobe Reader ETC)
– We also created an Install BSL Applications (Business Software Layer) for specific software per/pc/room
– Add the software to the BSL and choose Options
– Add Condition and choose Task Sequence Variable BSL equals “Students Desktops”
2. Let’s install sofware based on a variable
OK lets go a little bit further, we are now going to add the computer in the AD OU based in the computer variable of the collection.
– Go to the Network Settings, Apply Network settings and set Join a domain, fill in the domain name and in the OU part you choose LDAP://%OSDOUName% as stated in the variable.
Now we are going to set the options so the proper collection is selected.
– Go to Options, Add condition, Task Sequence Variable and choose Domain equals “Students”
– Made device collections based on rooms
– Filled in the variables for that device collections
– Set options for installing software based on device collection variables
– Placed machines in the proper OU based on device collection variables
Simple as that!
