SRV-records not resolved
Martin Rådbo
We try to use a simple srv-string, there we want people surfing to
www.latitud.net to be directed to www1 under normal circumstances and to
www2 if www1 is down.
The problem is that the client surfning to the website (with IE 6.0 and
Windows XP) does not resolve anything at all. We tried to check whats wrong
with the two srv-strings but without success.
Anyone?
Thanks in advance

There is no srv record visible from Internet. Otherwize it looks fine to me.
You biggest problem is convincing ie to ask for SRV records.

Outside of MS Windows 2000/2003, very few applications use SRV records.
So, you can add them to your DNS zone, but no one will be querying
them. I do not know of an easy way to direct users to www2 if www1 is
down, outside of a load balancer (which is not DNS-related).

SRV-records.
This is a pitty because as an ISP we can make everything fault tolerance
inside our net (with load balancing, raid, double servers and so on)
but if we have two different internet connections from outside, there is n=
o
way
to direct our customers to the second line then the first line fails.
Of course there is a way:
register a second (or third) dns for the domain name pointing to the secon=
d
line, but the caching problem is impossible to solve. People will get
redirected not before their dns has released the cached information and th=
at
is not usable.
