Hello, I just wanted to share an issue that cropped up in case it helps someone else. At some point in time, someone before my time enabled the Web Cache: HTTP content caching feature. We certainly do not need it as we have a large Internet pipe. It was causing an issue where we could not install our Sophos Anti-Virus program on any computers. The application would just bomb out during the install. My guess is maybe an old copy was cached and failing a checksum or something along those lines. Either way, disabling this feature immediately solved the problem.
