Hi All,

I have stand by system with same host name like the primary machine but with
different IP.
Is there any option to define A record on the DNS with priority? (like on MX
record)

P.S

I'm using Windows 2000 DNS

Thanks In Advanced!

There are no priorities for A records, but you can sometimes use subnet ordering to determine which IP is reported firsr. Whether
the client actually uses them though is entirely up to them. Most clients will just take the first IP reported and if it doesn't
work they will report an error.

Your best bet (other than a hardware failover router) would be to write a batch script that runs as a scheduled task to ping
availability and then changes A records (using dnscmd) accordingly. I posted something along these lines a year or two ago for
somebody.

If you have any programming skills available, writing this as a daemon service would not be difficult and would be better.
