Has someone solved the following problem simply?  I have NeXTs behind a
Sun gateway. I have a resolv.conf file that lists various alternative
nameservers, the gateway being at the top of the list.  If the gateway
goes down and then comes back up, the NeXTs are left in a state where
they can not resolve any host names that are not explicitly listed in
/etc/hosts. They do not refer to the gateway nameserver or any of the
other nameservers listed in resolv.conf. The solution has been to
reboot the NeXTs after the gateway comes back on the net. I'm looking
for a better way.  


Thanks for any suggestions.

A known bug in both SunOS 4.1.2 and NeXT OS 2.x.  Hopefully fixed in 3.0  
???
Only the first nameserver is actually consulted.  You 'shouldn't' have to  
reboot the client NeXTs, but they won't be able to resolve names until the  
Sun comes back up.  Does anyone have a fix for this?
