my business uses WinServer2003 with a RAID 5 array as fileserver for our network. Now can't login (pw that has worked for years not accepted)...at this point our software can still function but can't access other files on drive. Have tried CHNTPW, via live CD as well as Windows Password Reset and Hiren's...it appears to let me blank admin password, but when reboot still won't login. Tried promoting Guest to Administrator and logging in via that, but also doesn't work. Don't really want to re-install OS, any other options....Thank you very much in advance!!
