On occasion we need to create generic services to make them highly available.  This is the case when clustering the RMS server in Operations Manager 2007.

Here is the source: (Thanks to Rory McCaw for locating it.)

The issue is when the GetHosname() or GetComputerName() APIs are used.  Selecting the 'Use Network Name for Computer Name' option when configuring the generic cluster service has the effect of configuring the CLUSTER_NETWORK_NAME environment variable for the API calls.

In essence, this should be the choice for the generic services when configuring the HeathService and ConfigService.  Stay clear of this selection when configuring the SDKservice generic service cluster resource type.
