Hi, we have a weird problem, we have a sharepoint 2010 site runing on win2003 server that alwais work for users with windows XP, but only some times works for users with windows 7 64 bits. With windows 7 users when does not work, the browser said that the page could not be found, no matter the browser (we tried IE8, IE9, chrome and mozilla), however using a virtual machine with windows XP in the same windows 7 PC the users can browse the sharepoint site. When we do a ping to the server name, the DNS resolve the IP and response back, but even if in the browser we dont use the server name but the IP does not work. Other thing that is weird is that when we could not see the sharepoint via web browser, also we cannot loggin using terminal server, same error, server not found, and at the same time the XP PC (or virtual machines with XP) can connect using terminal server and web browser. Any idea? Thanks. p.s. my site is accessible via web http://pmp.poligran.edu.co/neocampus
