Error in Universal Time Conversion Utility: ''The persistence layer was unable to fulfill the request because it was unable to connect to the persistent store''

To resolve the issue:

1) Open the application.config file, located at %SystemDrive%\Documents and Settings\All Users\Application Data\Lnl (Windows XP or Windows Server 2003) or %SystemDrive%\ProgramData\Lnl (Windows Vista or Windows Server 2008).

2) For systems running SQL Server, the application.config file will contain a line similar to the following:
add key="ConnectionString" value="Data Source=SERVERNAME; Integrated Security=SSPI; Initial Catalog=AccessControl"

Ensure that SERVERNAME is the correct name of the database server, and that AccessControl is the correct name of the database itself. If the database resides on a different computer than the OnGuard installation, the Integrated Security setting may vary.

3) For systems running Oracle, the application.config file will contain a line similar to the following:
add key="ConnectionString" value="Data Source=SCHEMANAME; Integrated Security=no; User ID=USERID; Password=PASSWORD;"

Ensure that SCHEMANAME is the correct name of the schema in Oracle; this is typically LENEL. Ensure that USERID is the correct name of the database user, and PASSWORD is the correct password for the database user.
