Hi, I have a windows 2003 server that has been running reliably for a few years. However recently the LSASS service has been faulting Faulting application lsass.exe, version 5.2.3790.0, faulting module alockout.dll, version 0.0.0.0, fault address 0x0000be2c. A reboot of the DC does not fix the issue. Any ideas would be gratefully received. Richard

You seems to have account lock out tools installed in your server which is making a problem to lssas.exe to fix the problem you might have to unregister the aclokout.dll and monitor the server How to Remove the ALockout Tool To remove the ALockout.dll file from the computer At a command prompt, type regsvr32 /u alockout.dll. Delete the Alockout.dll value that is under the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\ Windows AppInit_DLLs After you delete the Alockout.dll value, the AppInit_DLLs registry key is blank. Restart the computer. Delete the ALockout.dll file from the Systemroot/System32 folder. http://www.virmansec.com/blogs/skhairuddin
