I got the following error when I tried to connect sql2000 from my PC (using Dial-up net connection) to the database server using this connection string:

VB

ConnectionString = "Data Source=XXX.XX.XX.XX;Integrated Security=SSPI;Initial Catalog=db_accounting_system; User ID=sa ;Password=***"

MSIL

Unable to open database. Connection string: 'Data Source=XXX.XX.XX.XX;Integrated Security=SSPI;Initial Catalog=db_accounting_system; User ID=sa ;Password=1***'; Error: 'System.Data.SqlClient.SqlException:

When Integrated Security is set to true (SSPI = true) the UID and Password are not used, instead the current Windows Login account will be used.

Hi Mark, I can't find any help in those sites.

Since I told you what the problem is and the site lists and describes each parameter that makes up a connection string, there is no more help to give you.
