Renaming default install of cfusion

Please help.

I have two web servers running Windows 2003 R2 NLB and ColdFusion MX 7.0.2 multi-server configuration. I am trying to set up a CF cluster between the two and have found that I must rename one of the CF installs. I have renamed the {jrun-root}/servers/cfusion directory to {jrun-root}/servers/cfusion2 and have modified the {jrun-root}/lib/servers.xml file to show:
<server>
<name>cfusion2</name>
<directory>{jrun.home}/servers/cfusion2</directory>
</server>

Once this is done, however, I am unable to start the Macromedia JRun CFusion Server service (nor either of the ColdFusion ODBC services). The cfusion-out.log shows:
"JRun server "cfusion" does not exist, the server root null was not found. Please verify that the C:\JRun4\lib\servers.xml file contains valid data for this server."

I've seen where others have mentioned changing the default install of cfusion to cfusion1 and/or cfusion2, but no one who has encountered problems while doing so. Is there something I've missed? Are there more files that I need to change?

Any assistance would be greatly appreciated.
