we are getting the below error while reeboting the mcafee webwasher appliance
tftp download : smsboot\x64\preboot.com error.
The issue has been sorted out.
THere was a boot sequence change happened, where the first boot option was changed as cdrom, TFTP then hard drive and then raid.
We changed the boot option and brought the raid to second. This resolved the issue and the box booted up properly.
