Error in Connecting to MS SQL 2005 via JDBC Driver

Question

Here's the setup
CF MX7 resides on a centOS wid Apache 2.0 webserver box.
I need to established a datasource connection between the
Coldfusion server and a MSSQL 2005 Express+SP1 database sitting on
a remote XP wid SP2 setup.
I've also downloaded and installed on the /lib folder of the
CFMX7 server the corresponding JDBC drivers (versions 1.1 and 1.0)
for the MS SQL server.
The thing is, this problem always occurs:
Connection verification failed for data source:
datasourcename
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for
JDBC]Error establishing socket.
The root cause was that: java.sql.SQLException:
[Microsoft][SQLServer 2000 Driver for JDBC]Error establishing
socket.
The datasource connection info is as follows:
CF Datasource Name: datasourcename_JDBCdriver
JDBC URL:
jdbc:microsoft:sqlserver://192.168.0.47:1433;DatabaseName=nameofdatabase
Driver Class: com.microsoft.sqlserver.jdbc.SQLServerDriver
Driver Name: mssql2005
Username: sa
Password: userdefinedpassword
I've already tried these settings:
* Enabled mix mode of authentication under the SQL server
* Affix a /MSSQLSERVER instance name on the jdbc url setting
"jdbc:microsoft:sqlserver://192.168.0.47\MSSQLSERVER:1433;DatabaseName=nameofdatabase"
but a different error had occured:
The root cause was that: java.sql.SQLException:
[Microsoft][SQLServer 2000 Driver for JDBC]The requested instance
is either invalid or not running.
so i remove it since its only an optional setting
* Configured the SQL 2005 Express, under the SQL Server
Configuration Manager, to listen to protocol TCP/IP under port 1433
(this is the ONLY ENABLE protocol)
I've checked using Telnet and netstat and the SQL service is
normally listening to the said port.
* Disabled windows firewall under XP (came with SP2)
and even tried using other JDBC drivers such as:
* macromedia drivers
* jtds driver
but to no avail.
Is the problem still within the MS SQL 2005 Express wid
XP+SP2 box or a connecting issue on the Cf server under the
centOS/Apache machine?
A little help would do wonders just about now.

Answer 1

I had the same problem, but do not have express version. In
the configuration manger, I viewed the properties of the enabled
tcp/ip protocol. On the IP addresses tab, I found that though the
IPs were enabled, the drop down beside active was no. I changed all
to yes, applied it and restarted my instance. Then in the cf
datasource I left the port blank and everything worked.
