The TFTP Server runs in a background mode, it does not have any user interface. There are number of ways to monitor and configure your server:
TFTP Server Configuration Manager
TFTP Server Configuration Manager is a special utility intended for TFTP Server configuration. You can run the TFTP Server Configuration Manager from the WinAgents TFTP Server group in Start menu. The main window of the application contains four property sheets allowing you to manage different aspects of the service configuration.
Figure 1. TFTP Software Configuration (page 1).
The first page allows to configure basic parameters of the TFTP software. You can specify TFTP root directory, port which the TFTP Server will listen, timeout and number of retries here. On the first page you can specify if the server will overwrite existing files during write requests. In addition you can increase base priority of the server process usgin the 'High priority level' checkbox. It will make the server more efficient under heavy load. Finaly, you can specify TFTP options supported by the server. Currently, the following options are available:
Figure 2. TFTP Server Configuration (page 2).
The second page allows you to configure access rights based on the clients IP addresses. There are two sorts of access rights available: default rights and per-client rights. The server applies default rights until the client has per-client rights.
The following rights are available:
We recommend to specify No Access by default and grant neccessary access rights only to restricted set of TFTP clients.
Also, you can add exceptions to the default rule. After you click 'Add' button at the bottom of the exceptions list, you will get the rule editing dialog. It allows you to configure custom access right for specified network or single IP address. The Figure 3 illustrates the rule editing dialog.

Service Manager allows you to manage the state of your TFTP Server. Please see special page for more information related to Service Manager.
During the operation time, the TFTP Server writes information messages into the logfiles. You can view these logfiles using any text viewer. The logfiles contain timestamped text messages. The server uses UNC timestamps, so you should apply timezone offset in order to get local time related to appropriate message.
For example, the text log can contain the following strings:
2002/10/15 12:03:41 UTC [1896/1776]: Listener stopped. 2002/10/15 12:04:44 UTC [2248/1896]: Starting TFTP listener... 2002/10/15 12:04:44 UTC [2248/1896]: Listening for requests... 2002/10/15 12:18:27 UTC [2248/1896]: Processing TFTP request... 2002/10/15 12:18:27 UTC [2248/1896]: Request from 192.168.1.2:53549 2002/10/15 12:18:27 UTC [2248/1204]: Write request for border-config; mode=octet 2002/10/15 12:18:27 UTC [2248/1204]: Write request for border-config completed successfully. 2759 bytes received from the client.
Each string corresponds to the following format:
yyyy/mm/dd hh:mm:ss timezone [ProcessID/ThreadID]: message
You can quickly access to TFTP Server log files through the 'Log Files' shortcut located in 'Start->Programs>WinAgents TFTP Service' group.
Windows NT/2000 EventLog
The TFTP Server uses Windows NT/2000 EventLog to write most critical messages. You can view EventLog using EventLog Viewer utility. TFTP Server messages have source named 'TFTPd'. Please refer to EventLog if you do not have any messages in TFTP Server logfiles - it will help you to solve the problem.
