Re: Multiple ADAM servers

I don't understand the DNS WINS Entry Name... This has nothing to do with WINS.

Anyway, I would do a network trace and verify that you are getting proper DNS resolution. The network trace will probably tell you exactly what is going on.

Hi,
Ok...so we created a DNS record, and have configured the hardware load
balancer. Since both the machines are part of Active Directory domain,
we have not done anything with respect to SCP. So in my code i changed
the connection string to LDAP://<DNS WINS Entry
Name>:389/O=Microsoft,C=US. I then ran the code to authenticate/bind
the user, but i am getting error " The Server is not operational".
Am i missing something?

Thanks!

In DNS. Talk to your DNS admins.

Load balancer hardware would have to be configured, there would be nothing you
would need to do with Windows.

Looking up SCPs is done by default with ADAM instances of machines that are part
of an Active Directory. You would have to make your application look those
objects up.

2. Depends on 1. Nothing will automatically redirect the traffic unless you add
the primary IP to the backup machine.

Hi,
I have a web application which uses ADAM (on Windows Server 2003) for
user authentication. Now, we want to have another ADAM server (in case,
the other needs to be down for maintenance, etc). I have already
installed ADAM on second server and created a replica of that existing
instance on this server. Now, i have following questions:

1. In my C# code, i do not want to refer to a specific server (first or
second), as anyone of them might be down. How can i do this?

2. If one of the servers needs to be down for some reason, what steps
do we have to take to ensure that all the traffic gets diverted to the
other server?

A quick respons will be highly appreciated.

Thanks,
Saumin Patel
