The Data Access service is unable to initialize because port 5724 is in use. The Data Access service must be able to use 5724 as this is the port used by the consoles as well as other Operations Manager components to communicate with the Data Access service. When the Data Access service is not running, users will not be able to use the Operations Console, Web Console, or Command Shell. Any connectors to 3rd party management systems will not work as well.
Another application is using port 5724.
Run netstat.exe –a to see what process is using port 5724.
