I'm new to the forums so bare with me on this.
I have a database running using SQL Server, this database is being inserted into and updated from many different locations, its mainly a database for use with .net/c#. I'm trying to find the source of a couple of queries that i know are running on the database as i can see them in the Activity monitor, however i cannot plausibly go through each individual file that could be running these queries as this would take a very long time. Is there an easy way using sql server management studio to find out where the queries are coming from or what type of application is being used. I have created a trigger on the table that is being updated to try to monitor the times that it is being updated, but that has not proved helpful.
