SUMMARY
This article describes how to set up a COM+ application on a cluster server.



Prepare the Server DLL

 * 1) Move all resources to node 1 to set node 1 as the active node.
 * 2) Create a folder on a local drive of node 1 (for example, E:\MyDlls).
 * 3) Copy the server dynamic link library (DLL) to the folder that you created in step 2.

Set Up COM+ Application

 * 1) Create a new COM+ Server Application named ExpTest on node 1.
 * 2) Add the server DLL that you prepared in the preceding steps as a new component in ExpTest.
 * 3) Test the installation locally on node 1 to verify that the COM+ application is set up correctly.
 * 4) Export ExpTest as a Server Application to a shared drive on the cluster (for example, X:\Share\Tst.msi).
 * 5) Move resources to node 2.
 * 6) On node 2, install the .msi file that was saved to the shared drive (for example, X:\Share\Tst.msi). This operation replicates the COM+ application to node 2.
 * 7) Test the COM+ application installation locally on node 2.

NOTE: The location of the COM+ application on node 2 is not E:\MyDlls; instead, it is C:\ProgramFiles\COM Plus Applications\.

Deploy the COM+ Application and Test

 * 1) On either node 1 or node 2, open Component Services.
 * 2) Right-click My Computer, and click Properties.
 * 3) On the Options tab, set the Application Proxy RSN value to the virtual cluster name.
 * 4) Export ExpTest as an Application proxy to Client.msi
 * 5) Copy and install Client.msi on the client computer, which registers the COM+ application on the client computer.
 * 6) Test your client before and after failover to verify that you have completed these steps successfully.

NOTE: If you get an &quot;Access Denied&quot; error message, make sure that your client identity can be authenticated by the cluster server. When you cross a mistrusted domain, you need to match user name and password.
