In order to PXE boot, the Boot.wim file is downloaded from the PXE server using MTFTP protocol. Some customers are seeing Boot.WIM fail to start or fail to complete the download from the PXE server. The cause is the MTFTP server will repeatedly stop and eventually restart. The issue is found after upgrading to GSS 3.3 RU11. This causes PXE boot failures and no PXE boot menu is presented.
PxeMTFTP logs show the following:

When boot.wim fails to complete loading, some customers are seeing the Windows Boot Manager with the following error code:
Info: A required device isn't connected or can't be accessed.
Ghost Solution Suite 3.3 RU11
GSS 3.3 RU11
The issue is most likely caused by service control events or interrogate events causing the service to stop due to a misconfiguration in the service itself
A drop-in fix is available and attached to this KB to address the issue until a permanent fix is available. To apply the fix, the Altiris PXE MTFTP Server service executable will need to be replaced with the drop-in executable attached.
