When attempting to start out w2k server we recieve an
error stating lsass.exe error - invalid security ID
structure. We have tried re-installing 2k over top of it
with no luck, we cannot start in any of the safe modes
either. When attempting to logon to recovery console it
tells us we have provided an invalid password and we have
retyped it over and over. Please respond with any
ideas....it is a webserver and we have tried everything
we know of...short re-formatting...(dont want to lose all
our website)
