User's DNS server entries point to our BSDI box (actually a secondary,
CIC maintains the primary). Mostly they work great. However, at any
given point in time there is usually at least one user who stops
getting DNS resolution. When doing a 'show sessions' from the PM
most users Host/Inet/Dest entry shows their dynamically assigned
IP instead of doing a reverse DNS lookup and getting the name associated
with that entry (such as dial-ip-1, etc). This is just a symptom of
the real problem because that user at that time cannot not perform
DNS resolution, making their connection pretty useless.
This problem starts and stops spontaneously. No actions taken by
us or the user seem to affect the course of a given 'incident',
including having the user reconnect. Sometimes it just last minutes,
sometimes longer.
Problem has NEVER occurred on the console or PCs directly connected
to our in house ethernet.
Anyone have any ideas? Livingston has not been either responsive or
helpful.
