Thank you Goran. This does head me in the right direction and I'm trying it as we speak.

I appreciate your help,

Randy

>You might need to build your own form but I think you could use the Win32 API function LogonUser(). I've not done this before so I can't say whether this will work or not - for example I can't say what might happens to the system if the userid / password is incorrect. Anyway I hope this function at least points you in a useful direction.
