[WD20] Kick client application based on database update (MSSQL)

I need to run a procedure in every client whenever a new record is inserted in the database (the record is not inserted by the client).

I know for HFSQL C/S you can use 'Server triggers'. But not for MSSQL.
Now I run a query every minute to see if there is a change but I need to have 'no latency' and running this procedure from every client every second will increase the load too much (WAN access).

What would be the best practice to do this?

Cheers,

Adri
