Hello All,

Just wanted to share this with the fellow boarders here. 
After setting up two new ltsp5 CentOS 6 / SL 6.1 servers,I experienced
something somewhat odd.
After doing some TC testing before putting these two new servers into
the wild in our school setting,  
This is after doing a couple days worth of CentOS repos updates, FYI. I
usually go by the rule, "Let a sleeping dog lie", in regards to getting
caught up in the updates revolving door,,but decided to keep these two
boxes updated out of the box.

My VM pxeclient would boot fine as long as I was using the default
ltspbr0 interface. If I switched to my hand configured eth0
interface ,along with the corresponding dhcpd.conf file the same VM
pxeclient would boot fine,,,but when getting to a login screen the TC
would hang for about 30-45 seconds then would see the "response from
server,restarting" thing. This happened every time.
After of course Googling found that doing the two following commands was
the fix for this.
I thought to myself,,,no way will this cure this deal!


Reboot the TC. 
Now on the eth0 interface (along with the ltspbr0 interface) the TC's
logs in fine. 
Don't have a clue what this combo is but this did in fact cure the

Take Care,
