You should already have set up at least a basic GroupWise system, as described in Section 36.0, Planning GroupWise in a Microsoft Cluster and Section 37.0, Setting Up a Domain and Post Office in a Microsoft 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 in a cluster.
