PXE boot hangs at a MTFTP prompt for 10 -15 minutes
说明
When trying to PXE boot a machine to a SDA or to an RSA, PXE hangs at an MTFTP prompt for 10 to 15 minutes. Sometimes it will complete the PXE boot after this waiting period and sometimes it will time out. Some PXE clients may seem unaffected while others do not, however all clients sharing the same DHCP servers (and the same DHCP ip pool will all exhibit the same behavior )
