Troubleshooting SCCM OSD Part 1

Part I : PXE boot

Many have been asking to write a blog on how to tracks the logs for OSD so here it is . It is in two parts.  Part I is PXE boot and Part II is After the Pxe Boot to Full blown OS. Since we are already in 2012 and 2007 has become obsolete, I will be taking 2012 logs to explain

Before we start troubleshooting OSD with Configuration Manager I would always say it saves a lot of time many times if the pre-requisites are to be checked, Especially if you find client is not PXE booting or if it fails after PXE boots immediately .  

If the client is not PXE booting checking the SMSPXE.log on the server where you have the WDS and confirm if the WDS is initialized. You could start the WDS service and check the log flow.

 This is how it should be

• You would see Provider loading
• It will show you the boot images in the WDS which will be opened ,files extracted and copied to boot folders which constitute the boot files for the WDS
• Then you will find PXE provider finished loading

If you see errors please act accordingly and make sure that the PXE provider finished loading

Few pointers

• Make sure that Boot images are send to PXE point or DP which has PXE
• Check for  event viewer and make sure there are no errors or warning related to WDS
• This is a wonderful article written by Frank Rojas which can help
  you with PXE problems. http://blogs.technet.com/b/configurationmgr/archive/2011/01/05/troubleshooting-the-pxe-service-point-and-wds-in-configuration-manager-2007.aspx

 Once this part is done confirm the following

1. You have created a Tasksequence and that it has a deployment \ Advertisemnt
2. Deployment is for the PXE (it can be Madatory (Required) or Available)
3. Referenced Packages are distributed including the boot images
4. Network Access account is specified  

Now that we confirmed that the PXE is loaded successfully. Let us now look at the SMSPXE when the client boots. In 2012 PXE message are pretty good , You could see the DHCP packet information.

First you would find the PXE client broadcasting. You will find the DHCP request (1). This contains the MAC ID and SMBIOS GUID. Now once this is got the device is checked for its presence in the database so that it knows if it is known client or not. DHCP reply would go with the boot file wdsnbp.com which will be downloaded and architecture detection happens once the same is done then the pxe client will again request to the boot action.  If we have a Mandatory advertisement then it will download PXEBootn12.com else
if there is no Mandatory then it will download PXEBoot.com

This checking is done by looking at against the configuration manager DB. In older version SMSPXE used to connect to DB and now it uses Management point to connect to DB and collect this information.

 With Mandatory advertisement \ Deployment which is required

Without Mandatory advertisement \ Deployment which is available

 

 This is the usual boot process

1)      A client is directed (by using DHCP Options or the PXE Server response) to download Wdsnbp.com

2)      Wdsnbp.com validates the DHCP/PXE response packet and proceeds to download PXEBoot.com or PXEBootn12.com.PXEBoot.com requires the client to press the F12 key to initiate PXE boot.

3)      PXEBoot.com or PXEBootn12.com  downloads Bootmgr.exe and the BCD store. The BCD store must reside in a \Boot directory in the TFTP root folder. Additionally, the BCD store must be called BCD.

4)      Bootmgr.exe  reads the BCD operating system entries and downloads Boot.sdi and the Windows PE image (Winpe.wim).

5)      Bootmgr.exe begins booting Windows PE by calling into Winload.exe within the Windows PEimage.

Once this is done you will find   the Configuration Manager screen as shown below

  

This is the completion of the PXE boot and once done from here on we get rest of information from smsts.log which first gets created in X:\Windows\Temp\SMSTSLog\smsts.log
