====== Named Problem July 2020 ======

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


Most machines have the following /etc/resolv.conf file
<code>
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
</code>

This is pointing at 
  * edinborodc06.edinboro.edu. 147.64.32.6
  * cailean.edinboro.edu. 147.64.32.189

On a DIG for name servers for edinboro.edu
