I have the same problem.
Does anyone know how to solve it?
Windows firewall - Exception - add programm
tftp 69 port TCP and UDP
I have the "bad filename" problem, as well, when trying to download switch configs. Windows firewall is disabled. I even disabled realtime protection from my AV program; no go.
I loaded some Windows updates recently (week of 12/18/06). I wonder of any of them is messing with me.
The error log in TFTP shows an IP different from the switch. (??)
I was able to download one set of configs before the update; then nada.
My problem has been solved. It seems that I was running HP Webjet admin, and it was using Port 69. So I just went to services and turned off the WebJetAdmin service off.
I am having the same problem as everyone in this forum had. I have my Firewall turned off, I updated my system MIBs from the SW site, and even went ahead and add the Config DL to the Firewall Exptions. I just keep getting Tranfer Failed. Bad Filename.
I am running the newest update for Toolset 9.2.
