Problem:
My SBS 2003 box was getting this error several times a day:
"IPBOOTP was unable to receive an incoming message on the local interface with IP address x.x.x.x . The data is the error code."
Process:
Most applicable suggestions I found said to either disable the DHCP Relay Agent service, or install a Win2000 hotfix. No luck for me, though, since the service wasn't installed, and I'm on SBS 2003.
Solution:
Microsoft.Public Usenet - IPBOOTP ERROR PLEASE HELP. Hurrah, disabling DHCP Relay on the LAN interface in RRAS manager.
