Subject: setting option tftp-server-name not working

I have some clients who are attempting to deliver Windows images using
PXE boot.  We're trying to setup dhcpd.conf and at this time it appears
the failure is on their end but I'm seeing some issues on dhcp.  We've
been asked to setup options 66 and 67 and while option 67 is sent in the
DHCPOFFER, I don't see option 66.

Using the "next-server" option works but they insist on getting option
66.  Why is the tftp-server-name not being sent?


You might try putting in some really long options (e.g., a long domain
name or other digital ballast) to force the server to overload the sname
option.  Unless they want both an sname AND an option 66.
