cannot connect/login error message

I am trying to connect to a virtual directory where there is an application
that was developed in .asp.net - it is linked to a sql server database. I am
using IIS, Server 2003 and SQL Server 2000 - same server - Any ideas where
this may be coming from? I posted this message under connect and security
sections. Thanks.

The ASP service Account is running under Networkservice Account which
is not priviledged in the SQL Server database. Either you change the
authentication in your application to SQL Server authentication
(Checkout the connectionstrings on www.connectionstrings.com for that)
or you change the service account of ASP to a domain or local account
which has to be priviledged in SQL Server.

Cannot Connect to an MS SQL Server

Hi,

I've developed an application that connects to an MS SQL server to read and write from a database. I have tested the program on about 6 computers (all on different networks and internet connections, etc...) and they can all access the database remotely just fine.

However, today I tried it on another PC (i.e. the 7th computer) and for some reason it won't connect. This computer is definitely on the internet as I can surf the web with it just fine, but every time I try to run the program it comes up and says that it cannot connect to the database. I can't remember the exact error message, but it was behaving as if the computer wasn't on the internet. What might cause a problem like this?

I did notice that this PC is running Norton Antivirus. All the other computers I tested on were not using Norton. Could Norton be the possible cause (i.e. might it be blocking a port or something like that). I will test it without Norton running, but I just thought I'd ask here too to see if anyone knows other possible reasons why this would be happening.

Thanks.

Have you tried to ping the IP/DNS name of the SQL Server machine?|||moving to SQL Server Data Access forum.|||

Yes. Norton Antivirus could be the cause of the issue. Try run your app with Norton disabled. I assume all your 7 machines are clients and the SQL Server is always the one.

One more thing you can check is to see if you have outdated alias defined on the 7-th machine. Use c:\windows\system32\cliconfg.exe or SQL Server Configuration Manager (if you app use sqlncli.dll) to check it.
