why did i keep getting a connection error?


i've been developing a webservice on machine A and one WebMethod of this
webservice will connect to SQL Server2000 on machine B using a connect string
defined in Web.config as below:

<add key="sqlDbConn. ConnectionStrin g" value="workstat ion
id="172.23.171. 226";packet size=4096;integ rated security=SSPI;d ata
source=172.23.1 71.226;persist security info=False;init ial
catalog=RVLabel ing_Joe" />

i'm sure the IP address as above is exactly the machine B's IP and database
name is correct! Also SQL server instance is running! but when i test the
WebMethod on IE through HTTP, i keep getting a error like this:

System.Data.Sql Client.SqlExcep tion: SQL Server does not exist or access
