We currently have GSS 3.0 installed, we are migrating from 2.5. I have setup PXE configuration(DHCP server is not on the same PXE server) and MTFTP. The problem we face is that when we try to network boot manually on our Dell optiplex machines we get:
pulls DHCP address
TFTP.
PXE-T05: unknown transfer ID
PXE-E36: Error received from TFTP server
