I have a SharePoint Foundation 2010 SP1 site running on Server 2008, using SQL 2008 R2 for the db. Today it will not come up, altho a subsite, on a different port does work if I open it from within Central Admin, or my desktop if I user http://servername:8001
to get to it. No patches installed last night so that is not the issue.
Not sure what to look for to fix this, I am not real familiar with SharePoint or websites.
