On a server running ESET Mail Security 4.3.10016 for Exchange, we're receiving the following error - "An error occurred while reading control file. The Personal firewall will not work." This is on plugin "Personal Firewall" This has only started SINCE we rebooted the server since installing ESET Mail Security. Previously it only had NOD32 on it. It never had a previous release of mail security. Mail security was running for a few days before the reboot as we had to schedule an outage. NO errors until the reboot. Now we get every few hours. Kicker? We have personal firewall disabled on this box (And all boxes.) So we're not having issues that we're aware of, but also don't want errors building up. This is an Exchange 2010 box.
