We have been looking into getting our OSD process to automatically change the computer name to what we want it to be for a while now but never really had much luck with it.
Reading various forums and blogs, many people have said to use WSNAME and many others saying use scripts, all of which never seemed to quite work for us.
What we wanted was a three letter prefix with the serial/tag number of our machines. Most of our machines (99%) are Dell’s and we wanted to use the 7 digit asset tag with a 3 letter prefix but things like the WSNAME only seemed to work with our HP’s using the %SERIALNUM% variable. Using this method, all our Dell machines were reporting the %SERIALNUM% as blank, so instead of:
It came out as just:
Not really much use!
So, we decided that we really needed to spend some time on this and get it working once and for all. After actually dedicating some time to it instead of just messing about with it for five minutes here and there, we finally got it working.
For those of you that know MDT, we used this with a mixture of Gather and Set Task Sequence Variable. Tested it, works a treat!
So, a quick how to guide for those wanting to know how to do it as we have really struggled to find a simple step by step guide to doing such a simple task.
We do assume that you have a good understanding of both MDT and SCCM at this point. You also need to have MDT installed and integrated into SCCM. If you need to create the MDT package, please read the next section, if not, jump to the instructions section.
MDT Package Creation
The easiest way to create the MDT package is after you have integrated MDT into your SCCM. Go ahead and right click on your Task Sequences and select Create MDT Task Sequence.
Run through the wizard and just create any old task sequence – you can delete the task sequence after. Part of creating the MDT task sequence is to create the MDT package if you have not already done so. Once complete, the MDT package then needs to be deployed and you should then be able to use it within your other task sequences.
First of all, you need to have MDT installed. You also need to make sure that you have ConfigMgr integration working, please note that this guide does assume that you have MDT fully up and running to use in your Task Sequences within ConfigMgr….if you need to know how to get this to work, leave a comment at the bottom of this post and we will look at getting a guide uploaded for doing that….
Edit your selected Task Sequence and just after the Deploy OS step, add your Use MDT Package step:
Then, directly after this step, add the Gather step and set it to Gather only local data (do not process rules)
Then, the final bit which applies the computer name, add Set Task Sequence Variable then make sure that the Task Sequence Variable is set to OSDComputerName. The value can be whatever you want it to be, the standard is:
This will set the computer name as the, you guessed it, Serial Number.
If you want to customise it slightly, just add the text before the %SERIALNUMBER%, so as an example:
Save your task sequence and it should work.
Few things to remember that are very important, this part must be added AFTER the Deploy OS step, but also BEFORE the Apply Windows Settings step.
