Eset Mail Security for Exchange 32bit v4.2.10016.0 SBS2003 Premium I just installed Eset Mail Security for Exchange on my server & it comprehensively broke all web access for the server & clients. It also broke access to the Router which is hung off the 2nd nic. I configured the proxy settings correctly. Turning off web protection had no effect. Uninstalling Eset Mail Security restored web access immediately.
