LSA Shell restarts

[Tom Goosman]

WinXP Pro workstation is restarting several times a day
due to LSA Shell errors. No viruses are (or ever have
been) active on this system.

Errors began occurring shortly after installing the .NET
framework version 1.1 via Windows Update on April 15,2004
(I highly suspect this is what started my nightmare.)

Event Viewer info:
Faulting application lsass.exe, version 5.1.2600.1106,
faulting module rpcrt4.dll, version 5.1.2600.1361, fault
address 0x000018ef.

So far I have tried the following steps to no avail:
1. System Restore
2. SFC
3. XP Repair installation

Can anyone recommend any further possibile fixes other
than a full format and reinstall?

Tom,
I've been running into a problem with the same module since mid / late April also. It manifests itself as a shutdown due to encountering a problem on both Outlook and Outlook express. The event viewer for Outlook shows:
Application mapisp32.exe, Version 5.5.1960.0
ModuleName rpcrt4.dll, version 5.1.2600.1361, offset 0000e8e6

For Outlook express the application is: msimin.exe, version 6.0.2800.1123

but the module and offset are the same.

I've virus checked the system multiple times and run Ad-Aware, but the problem still exists. I guess I'm no help but I'm in a similar boat and am looking for help myself
