Typically, you create a new domain on a new domain server, but if you need to create a new domain on an existing domain server, you can do so in the GroupWise Administration Console.
In the GroupWise Administration Console, click Domains, and then click New > Domain.
Use the information that you gathered on the Secondary Domain Worksheet
in the GroupWise Installation Guide as you fill in the fields.
Notice that, because you are creating the new domain on a server where a domain already exists, you cannot use the default port numbers.
Click OK to create the new domain.
