Doing some experimentation, and following the suggestion of removing the
offending zone and recreating it, it finally determined that the existence of
41+ PTR records for a single IP address was causing DNS Manager to display a
"Connection Error" and a red "X"
By keeping the number of PTR records for that IP address below 41, I am now able
to open the zone without any problem all of the time.
I'm not sure if this is the best way to do it, but I was able to modify the
reverse-lookup zone by:
1) deleting the zone from DNS Manager
2) making whatever changes I desired to the 135.157.208.in-addr.arpa.dns file in
3) recreating the zone.
Thanks for the help, for this and past issues.
