Daft question - is windows firewall off, and no access-list on the router?
Also, can you try another tftp daemon - i recommend tftpd32.
Failing tftp, you can try anpother transport protocol - ftp or scp should work okay.

Hi aleemuddin
I would guess at a syntax problem, but could you post your copy command and the console output?

Okay, try this command instead:
copy tftp flash://10.0.0.1/c2801-advipservicesk9-mz.124-15.XZ2.bin
It looks like your Windows is not set to display filename extensions - .bin should be the extension type for this file.

Can you create a test file in your tftp root, named test.txt?
Then try and tftp transfer this file:
copy tftp flash
10.0.0.1
test.txt
test.txt

can you able to ping the TFTP SERVER from router?

Hi Boopathi,
The OP screenshot shows a successful ping to 10.0.0.1.
Also, the tftp server output shows connection attempts (TFTP GET) so i think we have at least L3 and half L4 connectivity.
Hence a test of a simple file transfer using test.txt.

Ah good work!
You can leave the old file there for backup (only delete it if you need the space).
To boot to the new ios, use the:
boot system flash:
command, then write mem and reload.
You can do a show boot to see the correct syntax, it may be boot system flash:/
Good luck!

hi Ash,
at configuration level the command is boot system flash
Router(Config)#boot system flash c2801-advipservicesk9-mz.124-15.XZ2.bin
Router(Config)#
Router(Config)#wr mem
Router(Config)#
all commands accepted so i reload the router but again the old IOS boots.
pls advise.

Hi,
Firstly, I'm not convinced that's the correct boot command, I would expect something like this:
boot system flash:c2801-advipservicesk9-mz.124-15.XZ2.bin
or
boot system flash:/c2801-advipservicesk9-mz.124-15.XZ2.bin
Secondly, you may already have another boot statement which is interfering with this new IOS - check this with the show version command to see what IOS is booting.
OIf you have, delete the command and write mem, reload.
Regards, Ash.
