SYMPTOMS

Consider the following scenario:
  • You use a System Center Configuration Manager 2007 Deployment Feature Pack (OSD) task sequence to deploy a Windows OS Windows Management Interface (WIM) file.
  • The file is larger than 4 GB.
  • You use the multicase method to deploy the OS WIM file.
In this scenario, the task sequence and the deployment fails immediatly after the WIM file is downloaded.

Note The same Windows OS WIM file deploys correctly by using unicast. Additionally, this problem will not occur if you use the multicast method to deploy Windows OS WIM files that are smaller than 4 GB.

CAUSE

Thisissue is caused by a known problem in System Center Configuration Manager 2007 Service Pack 1 (SP1) R2. In this problem, hash calculations are not performed correctly when the WIM file size is larger than 4 GB.

MORE INFORMATION

After you install the hotfix that is described in Microsoft Knowledge Base (KB) article 971413, multicast OS deployments may no longer work. This includes Windows OS WIM files that are smaller than 4GB.

After you install the hotfix that is described in KB article 971413, a site reset is initiated. A site reset reinstalls all the site components. However, the multicasting session fails if the following conditions are true:
  • A multicasting session is initiated too soon after the site reset procedure.
  • The site reset procedure has not been completed.
  • Not all the components have completed their reinstalation process, in particular the components associated with multicasting.
The easiest way to resolve this problem is to wait awhile before you perform any multicast OS deployment. However, if multicasting deployment is still not working, follow the methods described here:

Method 1

  1. In the properties of the OS image, disable and then re-enable the Allow this package to be transferred via multicast (WinPE only) option.
  2. Disable and then re-enable the Multicast option in the properties of the multicast distribution point (DP).
  3. Reinstall WDS.
Note If multicast deployment on files larger than 4 GB is still not working, follow the next method.

Method 2

  1. In the System Center Configuration Manager 2007 console, under Operating System Images, right-click the OS Image that is being multicasted, and then click Properties.
  2. Click the Distribution Settings tab.
  3. Clear the Allow this package to be transferred via multicast (WinPE only) option, and then click Apply.
  4. Check the Allow this package to be transferred via multicast (WinPE only) option, and then click OK.
  5. Repeat steps 1 to step 4 for each OS image that have being set for multicast.
Note If multicast deployment on files larger than 4 GB is still not working, follow the next method.

Method 3

  1. In the System Center Configuration Manager 2007 console, under Operating System Images, right-click the OS Image that is being multicasted and then click Properties.
  2. Click the Distribution Settings tab.
  3. Clear the Allow this package to be transferred by using multicast (WinPE only) option, and then click OK.
  4. Repeat steps 1 to step 3 of this method for each OS image that have have being set for multicast.
  5. Disable the multicast DP in the properties of the DP role. To do this, click the Multicast tab, clear the Enable Multicast option, and then click OK.
  6. Monitor the MCSSetup.log file and the MCSMSI.log file. Wait until the files are uninstalled successfully.
  7. Reinstall multicast in the properties of the DP role. To do this, click the Multicast tab, check Enable Multicast, and then click OK.
  8. Monitor the MCSSetup.log file and the MCSMSI.log file. Wait until the files are installed successfully.
  9. In the System Center Configuration Manager 2007 console, under Operating System Images, right-click the OS Image that is being multicasted and then click Properties.
  10. Click the Distribution Settings tab.
  11. Check the Allow this package to be transferred via multicast (WinPE only) option, and then click OK.
  12. Repeat steps 9 to step 11 of this method for each OS image that have beingset to multicast.
Note If multicast deployment on files larger than 4 GB is still not working, follow the next method.

Method 4

  1. Follow steps 1 to step 6 of Method 3.
  2. If the server is not a PXE Service Point, go to step 5 of this method.
  3. If the server is also a PXE Service Point, delete the boot images from the PXEBOOTIMAGES$ DP and uninstall the ConfigMgr PXE service point role.
  4. Monitor the PXESetup.log file and make sure that the PXE service point is uninstalled correctly.
  5. Uninstall WDS.
  6. If you are prompted, restart the server.
  7. Reinstall WDS to make sure that you select both the Deployment Server and the Transport Server.
  8. If the server is not a PXE Service Point, go to step 12 of this method.
  9. If the server is also a PXE Service Point, reinstall the ConfigMgr PXE service point role.
  10. Monitor the PXESetup.log file and make sure that the PXE service point is installed correctly. If the log prompts to restart the server, restart the server.
  11. Add the boot images back to the PXEBOOTIMAGES$ DP.
  12. Follow steps 7 to step 13 of Method 3.
