DHCP

This morning my computer did not boot. On the monitor was “client mac addr 0011 09 84 4D AE Guid 0000000000000 DHCP� there was a X moving clockwise. In approx 3 min I was prompted for a boot disk. After rebooting 4 times it booted. Can anyone tell me what happen? How can I make a boot disk for the A drive ? I can't find away in system tools. I have winxp home.

Press escape when it tries to DHCP boot, you could also disable network boot in the BIOS.
