I have a Windows 7 machine (64bit Ultimate) I'm using as a file server... but only other Windows 7 machines can connect to it, NOTHING else can. I'm at a dead end here, I've tried reinstalling formating everything and it's still the same. I've tried disabling the firewall and it still can't connect. I've also tried setting the power settings to never turn off, but it's still not working. Tried changing the advanced sharing settings to using lowe encryption and turned off password sharing and nothing. My Macbook can't connect to it at all, but when I run bootcamp into Windows 7, it can connect to it fine. Even my Nexus 7 can't connect to it... NOTHING is working and I've tried everything I can think of. This machine is used for media sharing as well, so I can't run WHS on it. It needs iTunes and some other UPnP programs that just don't run on WHS. Oh and if I run remote desktop from the Macbook, it connects fine... It's just when I try to connect to the server it just can't. Only work around I've gotten is to restart the machine...

Hi, According to your issue, there must be something wrong with your Macbooks setting. Please try to contact Apple Tech for further help. Also, I found some solutions about sharing issues between Windows and Mac, more information please refers the topic below: How to mount a Windows shared folder on your Mac Hope this helps.Spencer TechNet Community Support

I've tried it with multiple devices, not just my Macbook. A Windows XP machine and my Nexus 7 also cannot connect. It's basically anything BUT Windows 7.

Hi, Did you get any error code or error information when you cannot connect to Windows 7 file server ?Spencer TechNet Community Support

Nope, none on my Macbook, XP machine or Nexus 7. The XP doesn't even see the file server in networks and when I manually connect, it says the connection isn't there or is offline. Same goes for the Macbook and Nexus7, just says the network isn't there.
