Have strange diveces not working in device!!manager  

what should I do guys?

Dont worry, they are not strange devices. Both the teredo interface and the ISATAP adapter are concerned with sending IPv6 packets over IPv4 infrastructure. These technologies are meant to help businesses transition to IPv6 infrastructure. For the consumer these come into play for IPv6 and Homegroups.

Regarding the ISATAP adapter, MS says the yellow exclamation mark can be safely ignored. It is meaningless and the device works properly though it may seem from the exclamation mark that it isnt. See this link.

On a Windows Vista-based computer or on a Windows Server 2008-based computer, the Microsoft ISATAP adapter appears with a yellow exclamation mark next to it in Device Manager, and you also receive an error message

For Teredo, you may want to keep it if you use IPv6 and/or Homegroups. Try right clicking on the device and uninstalling. After that, scan for hardware changes in the device manager menu bar, hopefully teredo will be installed correctly automatically.

Also, make sure you have IPv6 enabled/ allowed in your firewall. If you use ZoneAlarm, enable IPv6 in it.
