I'm having a problem with PXE across subnets. The workstation boots,
finds the dhcp server, finds the tftp server, downloads linux.1 and
linux.2 with no problem. It is unable to download linux3.tgz, however.


I've tried two different zen servers. I can tftp the file from either
zen server in windows with no problem. I can tftp it from maintenance
mode if I use a workstation as a tftp server. I can tftp it in PXE on
the same subnet with no problems.

A packet trace on the workstation shows that it gets so far into the
download and then begins getting ICMP 'destination unreacable' packets
from the server with the 'port unreachable' flag set.

It sounds as if the server is closing the conversation on that port.

Can anyone shed any light on this for me?
