[Casper] load balancing servers

Fri Jul 11 12:16:26 PDT 2008

10.5.2 has tons of network log in issues.  We are all running 10.5.3 on
server and client.  I will roll out 10.5.4 with version 6 of casper
probably as a self service policy once I test it to make sure it works
in our environment.

Same for us regarding G4s being touchy about netbooting to 10.5.2. 
Sorta on topic......we are still running 10.5.2 Server for both netboot
and JSS.  Anybody liking 10.5.3 or .4 better for either or both?  Any
new problems or hiccups if you are running newer than Server .2?

Thanks,
Matt
