Why is SCCM client installed when already in image?
Why is SCCM client installed when already in image?
- I may have asked this before so apologies if so
I'm just testing Win 7 deployment using standard SCCM created TS via the wizard. When you capture the package the SCCM client is included
When deploying the client, it appears, is reinstalled from scratch - Just that it adds another 5 minutes to the overall build
Was just wondering why its necessary to install client when it has already been installed via the capture TS
Whilst on the subject of speed I recall there's a pause of 90 seconds I think between package installs. Is that still the case in SP2?
Thanks

- Not sure if this applies to win 7, so forgive me if I'm wrong. My environment is XP SP3 and SCCM 2007 R2. When we build an OS image for deployment, one thing that needs to happen is the correct preparation of the SCCM client, so as to avoid duplicate entries in SCCM. This includes stopping the agent and removal of certificates. http://technet.microsoft.com/en-us/library/bb694095.aspx
This may why it is installed in the TS post installation. If you aren't correctly preparing the client as part of your capture TS, you should look at above link.- Marked As Answer byEric Zhang - MSFTMSFT, Moderator19 hours 0 minutes ago

- Hi Ian,
Before capturing image on the Mater computer which installed with SCCM client, you need to perform some preparation work, see the steps in the technet article that Rob provided. - Interesting - so you're saying that the standard wizard created capture task to install the client is not enough i.e. you must add some vbscript or other code into the TS to further strip the SCCM client before it can be considered "ready" for the image
So that being the case before I reinvent the wheel is there any code or anything out there I can use as a template - in my testing I'm using mixed mode so unsure if there are any computer specific templates
Ian Burnell, London (UK) - Doesn't the Microsoft Deployemnt Toolkit do this?
And on your other question, SP2 includes the hotfix in the client to cure the 90 seconds delay between packages. - Thanks Neil - I don't suppose you'd know what action or better still VBscript you're referring to in MDT?
Ian Burnell, London (UK) - This is not answered
I investigated this and my understanding is the SCCM task sequence "Prepare Configmgr Client" does what is in the KB article listed i.e. removes site code stops service etc. Therefore the client in the image should be "sid neutral" for want of a better word
Therefore same question. When doing a deployment using this captured image the TS to setup windows and configmgr REINSTALLS the client - ccmsetup.log states that the client is present and is the same version but still does a reinstall - which takes at least 5 mins and then the client initialises which takes another 2-3 minutes i.e. about 8 minutes lost - which I can't understand given the client is prepared and in the image
