Hi I am getting an object reference error  on opening a connection

my code is :

Dim k2Conn As New SourceCode.K2ROM.Connection()

k2Conn.Open("k2.ss.co.za", "[;];Authentication=External;User=Bryan;Password=H;Auth=Custom")

Any ideas?

I am assuming you are using 2003 correct?

You have Authentication as External are you using some external UserManger?  The only thing that looks out of place is the Auth=custom

 The expected connection string should be in the following format

[;]AuthenticatioExternal;User=Username;Password=password
