Changing the DEXIS database password

This procedure targets installations of DEXIS Imaging Suite (version 10). It will not work for older versions (9 and earlier) or DEXIS 11 and newer.
The DEXIS Imaging Suite database installation uses a well-known database instance name and password, allowing others to access your database, which contains sensitive patient information. Ideally, these should be changed to increase the security of your database.

During installation

During installation of the server, it is recommended that the instance name be changed from the default, “DEXIS_DATA”. Using the default name allows anyone to search for your database with a well-known name. Note that you cannot change the instance name once the database in installed.
You are unable to specify a different password during the installation process.

After installation

After DEXIS is installed, you can change your database password using the following procedure. Note that this procedure will work if you installed a new instance of the database using the supplied installation media.
On the installation media, browse to the following directory: “D:\Common\Software\ssmse2005\x86”, where D: is the drive letter on which the installation media is mounted.
Run SQLServer2005_SSMSEE.mis to install SQL Server Management Studio Express on your server. Use the default options in the installation dialogs.
Start the SQL Server Management Studio (Start → All Programs → Microsoft SQL Server 2005 → SQL Server Management Studio Express).
On the “Connect to Server” dialog, change the Authentication setting to “SQL Server Authentication”. The Login name is “sa”, and the password is in the user manual.
It is recommended that you do not use the default (well-known) password, and to use a strong password for your database. There are web-sites which will generate a strong password for you (such as: https://identitysafe.norton.com/password-generator) or will indicate how strong your password is (such as http://www.passwordmeter.com/).
On the left side panel, select “Security” → “Logins”. Double-click the “sa” user, and enter a new password on the General page. You will need to enter the same password twice to confirm.

Updating DEXIS to use the new password

Run DEXIS Imaging Suite (double-click the icon on the desktop). DEXIS will display an error (The following configuration errors were detected). Click “OK”. Click on the setting button ( ). Select the Data panel in preferences.
Check the “Edit Advanced settings” option. Click “OK” on the displayed warning dialog.
Enter your new password in the dialog. Press the “Verify” button to test the settings. When successful, select “OK” and restart DEXIS. You are now using the new password.
