Hi Chris,
Are you still using ColdFusion?
It sounds like you're on a Windows server, yeah? If so, adding this to your web.config file should do the trick:
<match url="(.*)"><conditions><add matchtype="IsFile" negate="true"><add matchtype="IsDirectory" negate="true"></add></add></conditions>
<action type="Rewrite" url="{R:1}.cfm"></action></match>
Otherwise, adding the following to your web.config for WordPress should work:
<rulename="company cfm"=""><matchurl="^company (.*)$"=""><conditionslogicalgrouping="matchall"><addinput="{request_filename}"matchtype="isfile"negate="true"><addinput="{request_filename}"matchtype="isdirectory"negate="true"><actiontype="rewrite"url="{r:1}.cfm"></actiontype="rewrite"url="{r:1}.cfm"></addinput="{request_filename}"matchtype="isdirectory"negate="true"></addinput="{request_filename}"matchtype="isfile"negate="true"></conditionslogicalgrouping="matchall"></matchurl="^company></rulename="company>
