tftp: SENT error:1, msg: File not found

[knite]

hi all,
i have this message appear each 4-5 min, i scanned the network for this traffic using etherereal but no luck I couldn’t find the TFTP source, as i can understand something is requesting a file from the switch which it is not available!
can any one help me plzzzz.

When you did the packet capture, did you monitor all ports to a mirror port on the switch?

You should be able to then set the 'tftp' filter in ethereal to find the culprit.

yes i did mirro all ports to the desinated monitor port, but no luck, i cant see any TFTP traffic and still have the events coming.

any more ideas?
thank you

Hi,
I am not sure, but as I remember I have a similar problem a few years ago. In my case, it was one server with HP JetAdmin installed. Disable this service solved the problem...
