Getting logon window on start

[Roy Goldhammer]

Hello there

I started building my own sql server when it was windows authentication.

Now i need to work on SQL server authentication.

I changed the mode to Mixed mode. In the first connection of the adp i need
to give the username and the password. So i give him and on the next time
the ado opens it always be open with that user.

When i installed the adp before on computer with Windows 98 it always gave
me a logon window

But now when i use Windows XP the logon windows never appear. Is there a way
to run the logon window?
