VMWare Warning: "[vmusr:vmtoolsd] Failed registration of app type 2 (Signals) from plug-in unity."

Problem

Server 2008R2 running under VMWare ESXi 5.5 produces the following error during RDP session:
[ warning] [vmusr:vmtoolsd] Failed registration of app type 2 (Signals) from plugin unity.

You can see the error in the event log.

Solution

The issue here lies in that the tools.conf file failed to be created during upgrade of VMTools during a recent ESX upgrade. Strange as this error is meant to be fixed in VMTools version 9.05, and yet this is the installed version. No matter, easily rectified.

[logging] 
log = true  

# Enable tools service logging to vmware.log 
vmsvc.level = debug 
vmsvc.handler = vmx 

# Enable new "vmusr" service logging to vmware.log 
vmusr.level = error 
vmusr.handler = vmx 

# Enable "Volume Shadow Copy" service logging to vmware.log 
vmvss.level = debug 
vmvss.handler = vmx

Save your new text file as tools.conf
See the table below for the location of the file .

OSLocation
Linux, Solaris, and FreeBSD/etc/vmware-tools/tools.conf
Windows Server 2008C:\ProgramData\VMware\VMware Tools\tools.conf
Windows Server 2003C:\Documents and Settings\All Users\Application Data\VMware\VMware Tools\tools.conf

Restart the VMTools service and you are done.
