Error code Services.exe - entry point not found

i'm using w2k pro sp4 512MB. this morning after installing windows updates, when rebooting I recieved the following msg:
Services.exe - entry point not found

The procedure entry point IsWellKnownSID could not be located in the dynamic link library ADVAPI32.dll.

the next popup window have the following msg:

the system is shutting down. please save all work in progress and log off.....this shutdown was initated by NT AUTHORITY\SYSTEM.

The system process C:\WINNT\SYSTEM32\SERVICES.EXE terminated unexpectedly with status code 128. The system will shut down and restart.

i can't get past this point. where do i go from here?
