[K12OSN] 8 Minutes to Open Open Office 2

[David Trask]

I can almost guarantee it's DNS related.  Here's how I know.  Last year I
ran my system with Samba/LDAP..../home on another server exported to and
mounted on the K12LTSP servers....AND I ran DHCP from another FC 1 server.
 With this setup...everything worked fine except OO was slow to
load....not 8 mins, but close to a minute or so.  This year...I am still
running Samba/LDAP....BUT the major difference is that DHCP is now back on
the K12LTSP boxes (I have two running in dhcp failover/load balance
mode)....now Open Office opens within seconds.  Even 25 at a time!
