This problem typically occurs when the /3GB switch or the /PAE switch is present in the Boot.ini file. When one of these switches is present, the computer may run out of available system page table entries. To fix this problem, try to restart your system in safe mode and add the System Pages entry to the following registry subkey.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management

To add this registry entry, follow these steps:

• Log on by using an account that has administrative credentials.
  
  
• Click Start, click Run, type regedit, and then click OK.
  
  
• In Registry Editor, locate and then click the following registry subkey:
  
  

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

• On the Edit menu, point to New, and then click DWORD value.
  
  
• Type SystemPages, and then press ENTER.
  
  
• On the Edit menu, click Modify.
  
  
• Click Decimal, type 31000, and then click OK.
  
  
• Quit Registry Editor.

That file comes with virus' and spyware. Just pull your hard drive and slave it in another PC then do a full virus scan on it.Also sounds like you may have too many USB devices directly to the USB ports on the computer connected. There are low-powered USB devices, USB devices and powerful. A single passive, self-powered hub can only handle a low-powered and one powerful at a time.

If the above registry work won't fix the problem than what i can only suggest you is to format the complete hard drive and reinstall it again as most probably it is effected by some powerful virus or any spyware.

Hi Jesse,

Thank you verymuch for solution to fix the Lsass.exe end point issue.

When our server was re-started last week, it suddenly showed this issue. We were unable to find a fix for this and were planning to re-install the OS. Then we decided to try out your solution and it worked like a charm. The registry already had an entry for SystemPages. We chagned the value as suggested, re-started the server and it was up as usual.

Thanks once again
