Example

// Set the Distributor and distribution database names.
string distributionDbName = "distribution";
string distributorName = publisherInstance;

ReplicationServer distributor;
DistributionDatabase distributionDb;

// Create a connection to the Distributor using Windows Authentication.
ServerConnection conn = new ServerConnection(distributorName);

try
{
    // Open the connection. 
    conn.Connect();

    distributor = new ReplicationServer(conn);

    // Load Distributor properties, if it is installed.
    if (distributor.LoadProperties())
    {
        // Password supplied at runtime.
        distributor.ChangeDistributorPassword(password);
        distributor.AgentCheckupInterval = 5;

        // Save changes to the Distributor properties.
        distributor.CommitPropertyChanges();
    }
    else
    {
        throw new ApplicationException(
            String.Format("{0} is not a Distributor.", publisherInstance));
    }

    // Create an object for the distribution database 
    // using the open Distributor connection.
    distributionDb = new DistributionDatabase(distributionDbName, conn);

    // Change distribution database properties.
    if (distributionDb.LoadProperties())
    {
        // Change maximum retention period to 48 hours and history retention 
        // period to 24 hours.
        distributionDb.MaxDistributionRetention = 48;
        distributionDb.HistoryRetention = 24;

        // Save changes to the distribution database properties.
        distributionDb.CommitPropertyChanges();
    }
    else
    {
        // Do something here if the distribution database does not exist.
    }
}
catch (Exception ex)
{
    // Implement the appropriate error handling here. 
    throw new ApplicationException("An error occured when changing Distributor " +
        " or distribution database properties.", ex);
}
finally
{
    conn.Disconnect();
}
