Would this be a SQL server ?


Hi, I was wondering usually SQL communication should be on port 14333. by filter using "browser", there's some indication of SQL services. Is a SQL server ?

Are the clients broadcasting to look for SQL services ?

One Answer:


The protocol is the Microsoft Computer Browser service, and that specific message is a master browser annonuncement sent by the elected local master browser, which is usually done by a server if there's one in the workgroup\domain. Such announcements carry a set of bit flags indicating the server type, one of which is SQL server.

Clients receive the broadcasts and could use it to determine SQL server capability\availability.
