I have been battling a virus threat that's been intruding on our Exchange Server 5.5. In an attempt to lock down this server I noticed that there are two shares on the system (c and e). However, these are not the administrative shres c$ and e$. If I were to change this to only administrative shares, would this impact Exchange in any way? Or does Exchange 5.5 need custom shares? I can't imagine why the previous administrator created these two shares instead of the default admin shares. Any help would be greatly appreciated!
