Microsoft's Sharepoint can be accessed by a web browser, or via a UNC path as if it is a file server. We store a lot of documentation on Sharepoint and I find it easiest to manage via UNC path. Lately I have noticed that my access to the UNC path could take almost a minute. After digging around a bit, I found that this is a known issue with Windows 7. Going to Internet Explorer's properties (even if you don't use IE as your browser) and shutting off automatic proxy detection will speed things back up.
