Peter, 

We're pretty sure it was the tftp server. Our data center preferred to host 
the tftp server on Windows, so we had something called WinAgents tftp as the 
primary server. We also had a linux hpa-tftp as a secondary. It appeared to 
me (and everyone else) that the problem was happening on both the primary and 
secondary. However as time went by it only happened ever again on the 
primary. I speculate that something was cached somewhere and made us believe 
it was happening on both, when really it was just the primary. Either that, 
or we just goofed up.

Now both primary and secondary are hpa-tftp. Over this past weekend I set all 
the clients to automatically reboot themselves over and over. Got over 15,000 
reboots without missing one. So, I'm saying we have a working system now.

Thanks for your Great Work on PXE and on tftp.

Larry
