svchost permissions

[Lucy]

Hi all,
I have a problem.
svchost has lost its permissions, whereby only local users have read
access and nothing else can modify it.
Is there a way to recover from this?
I need to add system and administrator but, being that I can't write
to it it's impossible to do..
Even though the machine is on a network I can't seem to see it as
being online, either.
But my main concern is getting the permissions..
If anyone has any advise.....?

I can't see why you want Write access to the file svchost.exe!? But anyway,
in an Administrator account, open a 'Command Prompt' window and type the
following at the prompt:


cacls C:\WINDOWS\system32\svchost.exe


This will give you a list of current file permissions. Then, to give the
file: 'Admin' FULL permissions, type:


cacls C:\WINDOWS\system32\svchost.exe /E /G Administrators:F


...do NOT give this file "Users: FULL" permissions!! Users should have the
following granted to them, if not already:


cacls C:\WINDOWS\system32\svchost.exe /E /G Users:R
