In windows explorer go to the root of your deployment share and make a folder called Logs. Share the Logs folder.
In MDT go to your Rules (customsettings) and add the following code in. You will need to change the server name and path.
SLShare=\\mdtserver\mdtshare$\Logs
Refresh your Deployment share.
After each deployment occurs a new folder in the LOGS is created with the computer name of the client PC and ALL MDT logs are copied from the client to the server for later review.
Also for best viewing results you will probably want to use the TRACE32.exe file. It even highlights the errors for you!
This tool is free and located in the file ConfigMgrToolsVersion 2 Toolkit!. Google search it.
Good Luck
