Dear all,
I don't know exactly what causes the ARP time out issue. I stop terminal server service, delete all /netboot file, re-run the terminal server again and re-create the configuration file, and replace the core.gz with the customized on - GUI + startup command, now the PXE boot run successfully.
The thing is, i cannot right click (choose menu), the mouse icon is became X instead of pointer format, does it mean i've missed some GUI packages to be included on core.gz file ?
Thanks for the advice.
