No Protection Technologies are installed

Created: 06 Jun 2011 | 5 comments

Seem that nearly all my non-administive users are not getting protection technologies from SEP.

i've tried the solution on the links below but there are no such policies on any GPO

also tried another solution from below, but no result.

my SEP is 11.0.6005.562 installed on server 2008 r2

i have XP, vista and window 7 computers

Tried to uninstall then reinstall the client antivirus package but its still the same

one of the solution that work temporarily is change the registry 

HKEY_CURRENT_USER\Software\Microsoft\windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing

and change the value data from

63c00 to 23c00

then i've restart my computer and all my technologies are back but when restarting again my computer, the reg values goes back to 63c00 and "No Protection Technologies are installed" again

please HELP

It seems you some GPOs applied causing this issue. Check if you have one of these:

  • “Enable trusted publisher lockdown”
  • Software Restriction Policies > Trusted Publishers

Check it with Start > Run > rsop.msc

"(...)The Registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing

Only affect "Check for publisher's certificate revocation" settings.(...)"

Try Installing Microsoft Visual C++ 2005 x86 redistributable.

Install "Security Update for Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package (KB973923)".

Reboot the system.

Also, Please check if the affected clients are all a part of an OU  that had the "Trusted Publisher Lockdown" GPO  active.

There are two ways to resolve this,

1- Disable "Trusted Publisher Lockdown" in the assigned policies. 
2- Import the digital signatures for all of the SEP  components into the Trusted Publisher Store. The signatures can be found in the properties for each of the SEP  components. The following MSDN  article addresses how to make these changes to the Publisher Store
