reboot the system, and before the OS loads, you will be prompted to do a Cntrl_E to enter the drac menu. in the menu, there will be an option to reset the drac to defaults, this will reset everything back to factory.

Thanks for youre answer !

In the Ctrl+E menu (DELL IPMI) you are meaning i have an option called "reset to factory defaults", but it seems the reset has no effect for the DRAC4 card.

The login into the DRAC4 webinterface did't work.

I have a Ctrl + D promt to enter the DRAC4 configruation interface directly, but there i can just set the ip address and other network configs. In that menu is not an option to reset the card.

If it is important to know: it's a  Dell Remote Access Controller 4/I

You need to run RACADM RACRESETCFG at at command prompt.  Then set your IP information again (after reset is done - up to 10 minutes) with RACADM SETNICCFG -S IPADDRESS SUBNET GATEWAY.

Thanks a lot. that works !

Cool ;)

Hi, Iv'e the same problem I can't login to the DRAC card..how can I get a command prompt after rebooting ??

What OS are you running?  Most Windows can open a Command Prompt by browsing to Start, All Programs, Accessories ... or typing CMD at the Run... or Search... boxes.  RACADM will do nothing though without OMSA installed.
