Error 6420 "Unable to discover Advantage Database Server"

Error 6420 signifies that Probate Plus has been set to operate with a dedicated remote database server (full client-server mode) but that the database server software cannot be found on the remote machine or that there is a communication problem between the client PCs and the server.

Double check that :

  1. You have purchased and installed the optional remote database server, called "Advantage Database Server".
  2. You have not inadvertently set Probate Plus to operate in "remote" mode when in fact it should be using "local" mode. "Remote" mode requires the use of dedicated, paid-for database server software running on your server machine. "Local" mode is free and operates on a peer-to-peer basis. The local mode ships with Probate Plus.
  3. You may require the use of an ADS.INI file to fine tune how Probate Plus interacts with your network such as if the ADS server is not on the same subnet, or to assist the discovery process of the server. E.g. you are connecting via VPN. Create a file called ADS.INI and place in the same folder as the Probate Plus executable.
  4. Detailed article on use of ADS.INI here:

Below is an example ADS.INI content where the server that hosts the Probate Plus data folder and ADS is called MYFILESVR and has an IP address of

The ADS.INI file tells Probate Plus to bypass the automatic network "discovery" process that is used when Probate Plus starts up.
