Just want to ask, i have tried so many times to configure PXE boot to one of my DP but unsuccessful. I got error "PXE-E77 bad or missing discovery server list" everytime want to network boot. Ok, below are the scenario: 1) DHCP is configured on Server A 2) WDS is configured on Server B 3) Configured 3 DHCP options: 060 PXE Client = PXEClient 066 Boot Server Host Name = WDS server ip address 067 Bootfile Name = \SMSBoot\Boot\x86\wdsnbp.com 4) Uncheck both "Do not listen to port 67" and "Configure DHCP option 60 to indicate that this server is also a PXE server". Kindly advice if there is still anything that i may be missing... The DHCP server got also port 43 configured and i got found 1 website that says if configure port 43, there will be problems... http://support.microsoft.com/kb/979720
