VBScript to join domain

I have a vbscript to join a domain. The issue is I have no error checking to see if correct user name/password was user. As of right now, any user name/password will "join" the domain but in actually, you aren't because a bad user name and/or password were user. I have a input box where you enter your user name and password, that info is passed on to the following vbscript and then "joins" the domain. I am looking for a way to error check it so if a wrong user name/password is entered, it runs the input box again (the input box is "JoinDomain.exe"). The only think I came up with was to try to map a network drive as my error checker. If a wrong user name/password is supplied, you receive an error. The issue is, it stops there. I heed help to make to loop back to the JoinDomain.exe or if someone has any other way to error check, that would be great. vbscript posted below:

Moved From The FAQ Section

Welcome to the forms. :wave:

A bad user name or password will result in a specific error with a specific error number which you can trap for. This will never occur in your code, however, because you are using "On Error Resume Next"

You don't want to do that. You want the error to happen so you can deal with it.

You can skip the drive mapping instead, use the WBEM locater & connect server objects to connect with alternate credentials and set remote boot privilege. I didn’t test this but I think its’ good. - Scott
