I have a Windows Server 2008 R2 virtual machine that is running on ESXi 5.5. I am seeing the following in the Application log files:
[ warning] [vmusr:vmusr] Channel restart failed 
[ warning] [vmusr:vmtoolsd] Failed registration of app type 2 (Signals) from plugin unity.
[ warning] [vmusr:vmusr] vmware::tools::UnityPlugin::Initialize: Unable to initialize Unity update channel.
[ warning] [vmusr:unity] ToolsOnLoad: Unity Plugin failed to initialize.
[ warning] [vmusr:vmusr] vmware::tools::UnityUpdateChannelInit: RpcOut_start() failed
I have already uninstalled and reinstalled VMWare Tools. Is this anything I should worry about?
