Check the MP_Control.log on your Primary Site server. Ensure the MP is healthy. You can also try to browse to http:// /SMS_MP/.sms_aut?mplist from another machine to see if the MP responds. 3. Clear Required PXE Deployments
If the MP is overwhelmed or the IIS services are down, it won't serve the variable file.
If the device is booting into WinPE but its IP address isn't assigned to a associated with a Management Point, the download will fail.

Does the device's current IP belong to a Boundary Group?
If you are seeing the error with Exit Code 14 in your SMSTS.log , your Task Sequence is failing before it even really begins. This error specifically indicates that the SCCM client cannot retrieve the variables.dat file from the Management Point (MP). What Causes Exit Code 14?
If the device was previously imaged and the Task Sequence was marked as "Required," SCCM might think the job is already done or stuck.
Ensure your Network Access Account is configured correctly and the password hasn't expired. Additionally, if you are using Enhanced HTTP or PKI, ensure the certificates are valid and the MP is correctly configured to accept communication from "Workgroup" computers (which devices are during the PXE phase). 6. Examine the SMSTS.log To get the "smoking gun," you must look at the log file. While in WinPE, press F8 to open the Command Prompt. Navigate to X:\Windows\Temp\SMSTSLog\smsts.log .
In some configurations, the device needs to authenticate to pull the variables.
