Hi keith,
I think you are on the right track by changing the variable RES_TIMEOUT to a
lower value, but you should also try and change RES_RETRY variable which
overrides the default value for the retry, which is 4. This value is the
number of times the resolver tries to query the name servers before giving
up.

Subject: AIX 4.3.3 DNS Timeouts?
Hi Guru's. Hope all had a Merry Christmas!
Question:
I am running AIX 4.3.3. I have two nameservers
set up in /etc/resolv.conf.
If I do a nslookup on a machine when both nameservers are up; no problem.
If I do the same nslookup when the first (in the list) nameserver is down, I
have to
wait approximately 75-90 seconds for the second nameserver to get the
request
and reply.
What can be done to get the timeout for the first request quicker? I have
serched the
Archives and the internet and the only thing that I have found is to set an
environment
Variable RES_TIMEOUT to a small number, but that does not work.
Any help would be much appreciated.
Thanks in advance.
