Networking & Firewalls

Docsvault uses following ports for communication between the server and the clients:


TCP Port 3831: To allow connection to the Docsvault Server Service (dvServer.exe)

UDP Port 1434: This SQL Server Browser service listens for incoming connections to a named instance of SQL server hosting Docsvault db and provides the client the TCP port number that corresponds to that named instance.


TCP Port for SQL server instance hosting Docsvault database: The Docsvault’s instance of SQL server listens on a dynamic port (between 49152 & 65535) selected randomly by the SQL server. The SQL clients first connect to the browser service (port#1434) to know the exact port number a named instance of SQL server is listening to for the requested database.


For more information on defining a static port for your SQL server or port forwarding from your router to the Docsvault Server, click Client Connection Info



If your firewall is application based (ex: Windows Firewall, Norton, McAfee, etc.)

The following Docsvault executables i.e Docsvault server and client along with the necessary MS SQL Server executables should be added to the exemptions/allowed list of the firewall. Docsvault installer automatically adds the necessary executables to the firewall exception list for the built-in Windows firewall.


Docsvault Client side:

-dvClient.exe (by default located at C:\Program Files\Docsvault <edition>\Client\)

Docsvault Server side:

-dvServer.exe (by default located at C:\Program Files\Docsvault <edition>\Server\)

-sqlservr.exe (by default located at C:\Program Files\Microsoft SQL Server\MSSQL10_50.DOCSVAULT\MSSQL\Binn\

  (Note: Replace MSSQL10_50.DOCSVAULT by your actual SQL instance folder if you used your own
   SQL server to host Docsvault db)

-sqlbrowser.exe (by default located at "C:\Program Files\Microsoft SQL Server\<90 or 100>\Shared\")
