We have a SharePoint2007 server running on a Windows Server 2003 Box. The box itself is quite old but has not experienced any weird issues.

Recently SharePoint has begun to show some strange behavior. One of the most annoying things is that once in a while, the sharepoint sever stops responding to requests outside our network. Internally, you can still browse everything that has to do with sharepoint but outside, nothing. If i reset the server it will start responding again. I am just not sure what makes it stop responding to users on the outside in the first place. Resetting the WWW publishing service does no good.
