I have not been able to update clients with new definitions on 2 different sites for 2-3 days now. Both the LiveUpdate logs show the same thing when trying to download definitions... some seem to be corrupted.

Corrupt  Symantec LiveUpdate  Symantec Endpoint Protection v11.0 English  SESC IPS Signatures Win32 11.0  1231965958jtun_sescw

I don't think this is caused by something local as it's happening on two completely different sites currently.

Cheers,
