We have pxe booting set as our primary boot order. We have a preferred server acting as our pxe rep as well. Pxe booting works perfectly fine when we boot only 1-3 or so machines at a time, or as many machines as we want as long as we boot them slowly, ie several seconds between powering on machines. However, if you rapidly boot several computers at once, it results in the pxe-e32 tftp open timeout. We are a school district with computer labs around 30 machines per lab. If students come in and boot up 30 computers at once, they will all open timeout. So far I have adjusted the mtftp timeout settings on the pxe rep however that did not resolve the issue. Any ideas would be greatly appreciated. Like I said, pxe booting fully works otherwise. It is only upon rapid booting do we receive timeout issues.
Thanks for the help!
