Got the following message in WINXP Home after rebooting
from a blue screen crash:

lsass.exe - Entry Point not found

the procedure entry point I_RpcGetExtendedError could not
be located in the dynamic link library RPCRT4.dll.

Any Ideas?????

Thanks
 
You must have installed something that replaced your rpcrt4.dll file with an
extremely old version. Check which version you have
(c:\windows\system32\rpcrt4.dll) and compare it to the lsass.exe file (also
in c:\windows\system32). I would recommend replacing it with SP1 version
(5.1.2600.1106) or newer. Go to
http://www.dll-files.com/dllindex/dll-files.shtml?rpcrt4 to download the SP1
version of the dll. Of course, I'm assuming you have SP1 installed.

Robert,

Thanks for the reply. I checked the version of
rpcrt4.dll and it was:

5.1.2600.1254

The one on the web site was .1106. I tried replacing it
by copying it to the system32 folder, but it retained the
higher number version.

Any thoughts??
 
Version 1254 does contain the routine reported as missing. You should not
try replacing it with an older version because the older DLL may not be
forward-compatible with newer apps. What version of lsass.exe do you have?
Perhaps there is a mismatch.

Are you seeing this error reported on each reboot? If it happens every
time, I would look for a software solution (Windows repair). If it happened
just once, I wouldn't worry about it unless there are other occurrences. An
intermittent failure would suggest a stability problem with the system. In
that case, I would try running memtest86 to check for flaky memory (most
likely cause of marginal problems), and something like Sandra 2004
benchmarks or Prime95 to stress other system components. These free tools
should run without errors. You can find them at:
memtest86 -- www.memtest86.com
Sandra 2004 -- www.sisoftware.co.uk
Prime95 -- www.mersenne.org

I run memtest86 for about 10 passes of the default tests (2-3 hours),
Sandra's CPU and memory burn-in tests for about 30 minutes, and prime95 for
about 30 minutes.

Note -- if you run Sandra or Prime95, I would recommend monitoring the temps
to make sure you don't overcook your processor or NB chip. Motherboard
Monitor (mbm.livewiredev.com) is a great monitoring tool for that purpose.
