vb.net data : Accessing sql server behind proxy
My app is running on a windows 2000 server with isa 2000 installed. How can it access an external sql server (using its ip) from within the isa 2000 firewall/proxy via code? Thanks Regards
You would have to configure your ISA server, but in my idea is that not
possible with AdoNet or Visual Basic. Cor "John" <John@nospam.infovis.co.uk> schreef in bericht news:%23jncfMRPHHA.3552@TK2MSFTNGP03.phx.gbl...

First, have you exposed your SQL Server 2000 to the network? That is, do you
have the protocols and interfaces enabled. Which port is it using? It might (just might) be using 1433. The port must be exposed through the firewall. Generally, one does not connect to an external (LAN) SS via IP/port--that's what the DNS is for. If you expose it to the WWW you're opening it up for attack--and it will be attacked--especially if it exposes the default ports. hth -- ____________________________________ William (Bill) Vaughn Author, Mentor, Consultant Microsoft MVP INETA Speaker www.betav.com/blog/billva www.betav.com Please reply only to the newsgroup so that others can benefit.

You will have to first create publishing rules on your ISA Server to publish
SQL Server. Basically this is to allow your application on the internet talk to your internal SQL Server via the firewall in a secure manner. For more information on creating server publishing rules, see ISA help. Here is some additional info: http://www.microsoft.com/technet/prodtechnol/sql/2000/maintain/proxy.mspx http://support.microsoft.com/kb/299673 -- Shijaz Abdulla MVP, MCSE:Security, CCNA Articles: www.shijaz.com/isaserver Forums: www.tech-links.org "If the only tool you have is a hammer, every problem begins to look like a nail."

Hi Shijaz
My problem is actually opposite. I am inside the ISA 2000 and trying to access a remote SQL server somewhere using the sql server's ip address. It may be possible to reverse the information provided in the article but I am about that ISA savvy to do it on my own.

Generally, it's safer (by far) to expose SQL Server over a VPN, and XML Web
Service or use a server-side application to access the data. -- ____________________________________ William (Bill) Vaughn Author, Mentor, Consultant Microsoft MVP INETA Speaker www.betav.com/blog/billva www.betav.com Please reply only to the newsgroup so that others can benefit.

Hi Bill
The sql server is remote with our hosting company. They have provided its ip address. I (from inside isa) need to configure isa to allow access to that sql server.
