Problem: There is a delay in establishing most internal network connections.

Most machines have the following /etc/resolv.conf file

domain cs.edinboro.edu
search cs.edinboro.edu math.cs.edinboro.edu eup.edinboro.edu edinboro.edu
nameserver 147.64.32.6
nameserver 147.64.32.189

This is pointing at

• edinborodc06.edinboro.edu. 147.64.32.6
• cailean.edinboro.edu. 147.64.32.189
