Hi, I have brandnew box with Windows Server 2008 R2. I'm having issues getting TFTP clients to load from it correctly. DHCP is on the same server with the following options set in the scope: 043 Vendor Specific 060 PXEClient 066 Boot Server Name 067 Boot File Name DHCP seems to be working fine. I see the PXE Client get an IP, Default Gatway and PXE Boot File name. When it attempts to download the file the following error message appears PXE-E79: NBP is too big to fit in free base memory" So far I have tried three different servers: -TFTPD -SolarWinds -WinAgents All produce the same results. Firewall is off and I have nothing else on the switch except the two machines. The server doesn't have the WDS role installed. I have tried various PXE boot files which I know are working on other deployements. Anyone have any ideas. Thanks
