Reviewing Known Issues, Limitations, and Recommendations for Installing or Upgrading to MDT
The following is a list of known issues, limitations, and recommendations for installing MDT:
· Ensure that the disk volume that contains the temporary folder that the Deployment Workbench uses has at least 20 GB of available disk space.
The Deployment Workbench creates large images and requires temporary storage during the image-creation process. The Deployment Workbench determines the temporary folder to use by performing the following steps:
a. Use the temporary folder specified in the Temp_Dir registry subkey, which is located at HKEY_LOCAL_MACHINE\Software\Microsoft\Deployment 4. Create the Temp_Dir registry subkey as a REG_SZ type that contains the fully qualified path to the folder to be used as the temporary folder.
b. If the TEMP_DIR registry subkey does not exist, then the Deployment Workbench uses the folder specified in the %TEMP% environment variable.
Ensure that the disk volume specified in the TEMP_DIR registry subkey or in the %TEMP% environment variable has sufficient available disk space.
· When installing MDT on Windows Server 2008 or Windows Vista, install the hotfix that updates the ADO.NET data services for the Microsoft .NET Framework version 3.5 with SP1 available from the Microsoft Support article Description of the ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows Server 2003, Windows XP, Windows Vista and Windows Server 2008: May 7, 2010.
