My intranet App doesn"t work without the internet connection

I have an application on ASP.NET installed on Windows Server 2003 and IIS 6.0
with SQL Server 2005, when my internet connection is broken the app doesn't
work. I have my LAN DNS. The app, website and DB are on the same server.
The dns is in another server. I usually use my app in this way:
http://servername/websitename . Please, I appreciate your help with this
problem.

Re: My intranet App doesn"t work without the internet connection

when its not working try to ping the server and see what ip address it tries
to go to. this may also depend on your router setup, if the servername
resolves to your external ip address then the router may be trying to send
it through the external interface which may fail if not connected to the
internet. also from the server try to ping the sql server by the same way
you reference it in the code, either servername, domain name or ip to see if
that works.

note that i have also seen clients get confused, and even when you have
internal dns set up to give you the lan address for the server they can end
up getting the external ip address... and once they have that you have to
close down everything and either reboot or do ipconfig/flushdns to get the
cache cleared... note that the flushdns won't work if something like outlook
or ie or maybe some other programs are still running, they seem to lock the
cache so it won't flush properly.

Re: My intranet App doesn"t work without the internet connection

Hi Dave:
The first option, I did it, when its not working I had ping the server, and
it resolved my internal address. The SQL server is the same server, and it
works too.

I would do the option with the flushdns, and I let you know the result.

Thanks for your help. I appreciate it.

Re: My intranet App doesn"t work without the internet connection

Hi Dave:
I did the ipconfig /flushdns on the APP server, and the clients, Disconecct
the internet, and try ipconfig all the clients resolved good the app server
Ip address, but the app continue working slowly. Please if you have any other
tick let me know.

Waiting for your help.

Thanks,

Re: My intranet App doesn"t work without the internet connection

"Working slowly" and "Doesn't work" sound like two different things.
And both cases usually have error responses and/or logging that
indicate next steps to troubleshoot.

Can you clarify exactly which problem you actually have? It really
sounds like the problem is either in your application, your
configuration of the application, or configuration of your internal
network's routing.

It sounds like your application is referencing its dependent resources
(like SQL Server) using the External name/address, in which case when
the Internet connection is gone from the server, that name will fail
to resolve (since the inbound Internet connection is also disconnected
and fails) and thus things can take a long time to timeout and
eventually fail.

In combination with what you are trying (which is to make sure names/
routing are connected regardless of how the server is connected to the
Internet), you need to make sure the application is actually using the
correct names to resolve to IP addresses.

Re: My intranet App doesn"t work without the internet connection

Hi David:
I'm sorry, but I'm using incorrect the words. My application is working
slowly, what I'm trying to say, because it works, but slowly when the
internet connection fails.

Re: My intranet App doesn"t work without the internet connection

ah yes, VERY different. check the order of your dns servers. if your
internet server is before your internal server you will be waiting for the
internet one to time out before using the internal one.

Re: My intranet App doesn"t work without the internet connection

Hi Dave:
Thank you for your help. I have reviewed this part, and it isn't, because mi
internal DNS is first, and later the dns of my ISP.
