hi. I am working presently on a friends computer. they have windows 2000 pro installed and are getting an error that says this: LSASS.exe entry point not found. The procedure entry point elsslush event log could not be located in the dynamic link library. ADVAPI32.dll then when they click onto the ok in the errror message the pc shuts down and then says this: system process cwinnt/system32,terminated unexpectitly shut down. Could any one help with this error? They told me that he went into his add remove programs and for some unknown reason he decided to remove one of the windows updates and he does not know which one he removed and after doing so they started to have this error. Do I have to now reformat the hard drive and reinstall the os? They can not get windows to log on as soon as it boots up you get the error then it shuts down please any ideas?
