This happened after installation of Service pack 1 on Exchange server 2013. According to ME2870416, this issue occurs because Exchange Server Setup tries to locate the GlsPerformanceCounters.xml performance counter definition file in the wrong location. The article provides a couple of suggestions on how to fix this.
EV100552 (Troubleshooting MSExchange Common 106 Events) provides some suggestions on how to fix this type of problem.
I've found a workaround - just add the performance counters for the RPC Client Access Service:
1. Start EMS
2. Add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup
3. New-perfcounters –definitionfilename "C:\Program Files\Microsoft\Exchange Server\V14\Setup\Perf\RpcClientAccessPerformanceCounters.xml"

See MSEX2K3DB for information on troubleshooting this problem.
