Is there no one who can answer this?

Hi,...

Can anyone answer a quick question..

I have two DNS servers running on Win2000 on DC's.

I have configured DNs to listen for requests only on the
interface IP's for the DNS servers, so we have both
servers listening for requests. All other member servers
and desktops are configured with the Primary and secondary
DNS IP's
Problem is if one of my DNS servers goes down,...then
other servers will still try to contact the DNS server
that has gone down. This will ultimately result in a
delayed response.
Is there a way to set a time-out so if one DNS servers
goes down there is no interuption to requests..?
..

Actually it is supposed to work that way automatically.
How do you know this is the delay? (How are you determining
this, and what is the length of time?)

Clients do this automatically (it might take a few seconds the
FIRST time but after that the clients should stick to the "working"
server until the other returns.

And also "servers" going down should be fairly
uncommon at least during "business" hours.

If the DNS server that goes down is the primary, this is expected.
Seocondary server will use the refresh, retry and expire in the SOA to
cantact the primary. If the server is using notify the name servers on the
name server tab and there is an incremental zone transfer any DNS with this
option set will notify all DNS servers on the Name server tab.

You can increase the refresh and retry values to a higher number, but if
there is a change in the primary it takes longer for the data to be
propagated to the secondary servers. If you turn off notify the DNS servers
will use the refresh retry values. Of course this means your secondary
server may have bad data for a longer time after a change.
