Hi detoam,
Welcome to Microsoft Answers community.
Microsoft is working on IPv6 related issues and soon will come out with some Fix.
Try the below methods:
Method 1:
a. Click "Start", type "services.msc" (without quotation marks) in Search Bar and press Enter.
Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue.
b. Right click the "Peer Networking Grouping" service and choose Properties.
c. Please check if the service is started; if not, please click the Start button and see if it works.
d. You may also choose Automatic next to Startup type.
e. Click OK.
Method 2: Try resetting TCP/IP stack.
To reset the TCP/IP stack go to this article and either click on "Fix it for me" or follow the instructions to fix it yourself: http://support.microsoft.com/kb/299357
Hope this information is helpful.
Let me know if this worked.
Thanks and Regards:
