1. From the Start menu select Run
2. Enter the following command including the quotes:

   "C:\Program Files\Symantec\Symantec Endpoint Protection Manager\bin\LuCatalog.exe" -cleanup

   This command will unregister all Symantec Endpoint Protection Manager content from LiveUpdate. We will then proceed to re-register the content again with LiveUpdate.

Hi Sandip,

Thats exactly what i mean. The revision dates back to April 2009, please help me update it.

Yes I did and it worked, Thank you Rafeeq.

Hi -

I have exactly this problem, dating from 1/21/2010.

For some reasons only 50 of my 650 clients are showing a definition date of 1/21/2010 - the rest are current.

I've run:

• Lucatalog.exe -cleanup
• Lucatalog.exe -update

with no effect.

My SEPM version is 11.0.5002.333 and the clients are various versions of SEP 11.

Any ideas?

Thanks!

Rob
