I am having difficulty connecting to SQL Server 2000 on one of our
servers via a VB6 program on Vista. I can connect fine to a different
server, but it gives me the following error with the server in
question:

"Unable to connect to database. Please check your internet connection
Error# -2147467259
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or
access denied"

Using the program, I am able to access the database just fine while
running on Windows XP, but when I run the program on Vista, it gives
me that error message for that server. If I change the connection
string to a different server address, it works fine on Vista. What
differences in the servers might cause this?

Here is my connection string:
"driver={SQL Server};Server=ipaddress;Uid=userID;Pwd=pwd;databa se=db"

Is the firewall open for port 1433?

Difficult to say. Is SQL Server running on port 1433 on both servers?

The SQL Server Config tools will tell you what port(s) have been assigned.
SS 2000 broadcasts and handles the incoming requests and maps to the ports,
but if the firewall blocks them...

Yes, it is open for port 1433. I can connect to a separate Server
using the same connection string, except for the IP address, and it
works fine.

I can also connect to both Servers using the application on Windows XP

So, there is something different about this particular server--assuming you
can connect to other servers from the client.
Have you run the surface area config tool on the target server?

As that server is running SQL 2000, there is not likely to be a surface-
area config tool.

But, yes, something appears to be special with that server.

TerpZebra, could you post the first 50 lines or so of the error log
for that server instance?

The SQL Server configuation tools will have to do. Make sure the defaults
are over-ridden to make the server visible. Since SP3a SQL Server 2000 is
configured to be invisible to the net. The TCP/IP protocol is disabled. See
http://www.databasejournal.com/featu...le.php/3334851. He
discusses the SQL Server Network Utility that's used to make these
configuration changes.
