I designed a system, works well on my machine but fails on others machines.

I create an ADO connection, passing the Uname and Pword and on my machine with this connection.
<conn>
ConnString = "Provider=MSDAORA.1;User ID=Uname;Password=Pword;Data Source=Servername;Persist Security Info=true"
</conn>
Again, this works in the IDE as well as the exe on my machine.

One error is TNSfile cannot connect. All tns files are updated for the new server and they cannot TNSPing the systems either.

Another is null password and will not connect. Arrrghhh

I'm thinking its the Oracle install. Nothings standardised here.
