Hi Rahul,

You can create a queue table in which Main exe will put requests for pings. Than you can have multiple ping exe checking that table for unprocessed requests. If ping exe finds one, it'll try to lock the record to make sure that another process doesn't work on it already. If record lock is successful, it will start pinging. The result is than written in the record, record is marked as processed by ping exe and unlocked. The ping exe's could run on the same computer or even on the separate computer or computers.
The main exe will check the queue table for the records with completed pings but not processed by main exe yet and process them.
