Item: 069 HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors
Description: Dell Network Port
Path: LEXLMPM.DLL
MD5: File not found
FileDescription: LEXLMPM.DLL
Registry path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\Dell Network Port
Certificate: File not found
If you don't have the Dell/Lexmark printer any more.
As for the entries in your second post, get rid of this one:

MD5: File not found
FileDescription: isPwdSvc.exe

But leave the rest alone, they show up on everyone's system (Autoruns shows them as well under "Drivers" as "File not found").
