Router#show running-config

Many thanks in advance

This pretty much the default configuration for the router. No IP addresses. Two things:
- Do a "sh start" to see if NVRAM contains the configuration you want.
- make sure your configuration register is set to 0x2102. This can be seen on the last line of output from "sh ver" command. If it is not do the following:
config memory, which will load the config from NVRAM and then
config t
config-register 0x2102
Hope this helps,

thank you, it worked from the commands i could see that the config was still there and change the config-register bits to 0x2102 it then worked.
Thanks

Simon,
It appears from the config, that not only do you not have an IP address configured on the router, but it is shutdown as well. The same is true for the ATM interface.
Without knowing the exact circumstances around this problem, it could be something as simple as forgetting to write the config after you set it up (changed it). Then at some point, the router was reset or lost power and reloaded the start-up config.
Just a guess.
