Determining Cluster Node

Every once in a while I get asked, “How does one determine what node of the cluster the currently running code is on?” One of the easier way to find out is to poll the registry.

<cfregistry branch=”HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl ComputerNameActiveComputerName”
action=”get” type=”string” entry=”ComputerName” variable=”ComputerName”>

  1. Doesn’t look like that’s right. Each of my cluster nodes (xx1a, xx1b) reports its own name in the ActiveComputername, but only 1b is really active. I would have expected xx1a to report xx1b as the activecomputername.
