TCP/IP Connection to new Windows2003 SQL Server


TCP/IP Connection to new Windows2003 SQL Server Francois
7/19/2005 2:40:02 PM
sql server connect: I've just dropped a new Windows 2003 SP1 server with SQL Server 2000 SP4 in
my hosted center. That server replaces an older Windows 2000 based server
running SQL Server 2000 SP3. I have a firewall-firewall VPN setup between my
office network and the data centre. I also have two seperate domains setup,
one for the office and one for the data centre.

The problem is, I can't seem to be able to connect to the new database
server the same way I used to with the Windows 2000 server. Both servers are
in the same rack right now, and I can access the DB on the old machine no
problem. I suspect tighten security settings on the Windows 2003 server is
giving me grief, but what?

TCP/IP connection just doesn't work on the new server. I can only connect
with named pipes, but it's a bit of a process. I can still connect on the
old server with either TCP/IP or named pipe. Here are the steps that I
discovered allowed me to connect to the new DB server:
1. Open the Client Network Utility and create an alias for the server for
the Named Pipes network library.
2. Open windows explorer.
3. In the address bar, try to browse the c: drive of the server with this:
\\newdbserver\c$
4. A dialog box will pop up asking for a user name\password. Put in the
username preceded with the domain name (domain\username) and the password.
5. Once you can view the C: drive, open query analyzer and connect to the
database.

If I don't follow the steps above, I either get the dreaded Msg 18452
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user
‘(null)’. Reason: Not associated with a trusted SQL Server.

Can anybody explain what is going on? What changes in Windows 2003 SP1 is
causing this? Or is it in the latest SQL SP?

Thanks,

Francois

Yeah, I've done that and it is listening on the server's IP.

I think that I might have figured out why it behaves the way it does with
Named Pipes. Given the steps that I have to take in order to successfuly
connect, the problem is obviously security related. The old server is
actually a domain controller, the new one isn't. That has implication from
an authetication's perspective, but don't ask me to explain it...

Bottom line, TCP/IP connections are still not working. I need to promote
the new database server to domain controller. I assume that when I do, the
problems will go away (I hope).

Anybody else have any insight into this situation?

Thanks,

Francois

Can you remote into the new server and look at the SQL Error log to see if
the server is listening on TCP?
