[Thinstation-general] intermittent pxe failure

[Larry H. <lar...@co...>]

I have a very strange problem. I have 12 thinstations that I'm pxe booting. 
There will be times when they all boot normally. Other times, most of them 
fail to boot. They get as far as 

Loading vmlinuz.............. 

then eventually they time out and say

Could not find ramdisk image: initrd
boot:

If I then reboot the same PC sometimes it will then boot, other times the 
problem will continue many times over. Once I get a PC to boot, then it works 
flawlessly with no further problems.

I have tried using different tftp servers, and changing DHCP settings such as 
specifying either an IP or a hostname for the tftp server, but I can't find a 
pattern to the failures. At the tftp server, the log shows the client 
retrieving the vmlinuz file, and then no further communication.

Any ideas?
