You should already have set up at least a basic GroupWise system, as described in Section 21.0, Planning GroupWise in a Windows Cluster and Section 22.0, Setting Up a Domain and Post Office in a Windows Cluster. As part of this process, the System Clustering Worksheet and the Network Address Worksheet were filled out. If you do not have access to the filled-out worksheets, print the worksheets now and fill in the clustering and network address information as it currently exists on your system. You need this information as you implement the Internet Agent (GWIA) in a cluster.
