This article provides brief information describing possible causes and steps to resolve the following error:
Cannot start TFTP Server. A TFTP Server is running on port 69.
All ETS versions
Any of the following causes the error:
If your system tray contains an icon that depicts two desktop computers, this indicates that you are already running TFTP Server. Double-click the icon in the system tray to open the already running TFTP Server.
1.Open Command Prompt.
2. Enter netstat -a.
3. Identify any items under the Local Address column that include:69 or :tftp.
4. If another program is using port 69, you need to close that program before you can run TFTP Server.
Cirrus is fully compatible with the ETS TFTP Server service and uses that version of TFTP Server, but you cannot run the Cirrus version of TFTP Server if the ETS version is already running.
Consult your network administrator for assistance.
