Hi.
If like us you are on Windows 2008R2 and others could have the same issue our SEC stopped working as we couldn't install new clients this week they couldn't connect to the share for \SophosUpdates on the server it was all down to this.
Basically our user that was created for the share was in the admin group and the latest patches broke this. So either remove that user from the admin group or do the registry fix.
