The Isah Mobile Sync Service is a WCF.NET 3.5 service, and if WCF 3.5 is used with IIS 7 or IIS 7.5, WCF must be registered once. To register the service, start a command prompt (cmd.exe) as an administrator and execute the following command:

"%windir%\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -r -y

Now modify some of the settings in the Web.Config file of the Isah Mobile Sync Service. Open the Web.Config file in a text editor to modify it. The default path to the Web.Config file is C:\inetpub\wwwroot\Isah Mobile Sync Services. Change the following data:

1. Connection string for the database: Configure the SQL Server instance, the database name and the database login:
   • Data Source: Enter the instance of the SQL Server.
   • Initial Catalog: Enter the database name.
2. Specify a user to be used by Isah Mobile Sync Service to access the Isah database:
   • Replace Integrated Security=SSPI by User Id=xxxxx; Password=yyyyy, replacing xxxxx by the user name and yyyyy by the password. For this configuration, you can specify the default database user 'IsahIsah'.
3. Enable logging if required:
   • You can turn on logging for the tables to be synchronized. You can set the table logging in the system.diagnostics section: set the SyncTracer value to 1, 2, 3 or 4, and enter a valid path for the log file in the initializeData field.
   • You can log any error messages that occur in the web service. You can set the error logging in the appSettings section: set the LogServerMessages value to 'True' and enter a valid path for the log file in the LogPath field.
