You should slow down and try to explain your question again.
You are saying you believe you are passing the correct connection string to your sql2005 database, but it's giving you a bad value?
What do you mean by "error value not null"?

1) Post the actual code you use (you can modify sensitive information like username/password/ip addresses)
2) Post what the actual error message you get is
