• Cannot start the VMware VirtualCenter Server service
• Manually starting the VMware VirtualCenter Server service by navigating to Computer Management > Services and Applications > Service > VMware VirtualCenter Server fails
• You see the error:

Windows could not start the VMware VirtualCenter Server on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 2.

Solution:

• Stop the IIS Admin Service and start the Virtual Vcenter server resolves the issue.
