[syslinux] Long delay to check for configuration files

[behrad at rayavaran.com]

Hi
 
Sometimes booting from the server last for a few minutes to show the menu. It is looking for pxelinux.cfg/C010200202 and pxelinux.cfg/C01002020 and so on and while in normal situation it takes less than one second for all of them, in this situation it lasts around 20 seconds  for each. I am using Microsoft Win2k3 tftp server and even restarting the tftpserver service is not helping.
