Which user id and password should I use to enroll?

You need to use the user id and password that you also use when logging on to the network with your workstation. The user id usually uses the format: jbakker@tools4ever.com

Which domain should I use?

Depending on the wishes of your organization you will need to enter a domain name or it might be preselected for you. If the domainname is empty by default, please enter the domain name 'SSP'.

I'm receiving the error "Unknown user id or bad password (1326)". What should I do?

Check the information you entered. You probably made a mistake entering your user id and/or password. Please enter those again.
