manki

I disjoined the windows 2000 PC from the domain, i put it on workgroup,with the intention of rejoining it back to the domain. It rebooted, after rebooting i could not log on i.e using the local administrator account I get error message and on the logon screen i dont have the logon to PC option, neither do i have the option to log on to the domain, All I have is the login name and password option.( I dont have that drop down option where i can choose to either log on to the domain or local on the PC)

Please somebody help, I am trying to avoid a situation whereby i have to reinstall the OS and everything all over again
