1. Open command prompt with administrator credentials (Find CMD and right-click - Run as Administrator).
2. Enter netsh environment. Type "netsh" and ENTER.
3. "int teredo" and ENTER
4. "set state disabled" and ENTER.

6. Open command prompt with administrator credentials once again.
7. netsh + ENTER.
8. "int ipv6" + ENTER
9. "set teredo client" + ENTER
10. Open Device Manager and Scan for new hardware.
11. Select "Show hidden devices" from the View menu. You will now see that it is present without errors with any luck.

Martin... I followed your instructions and did a "scan for hardware changes" since "scan for new hardware" does not appear as an option in device manager, and teredo still is not there.. any other suggestions.

thanks

Ok before we go deeper into this than we need to,

What OS are the two systems running?
Do you want to use Homegroups or Workgroups?

teredo will only be needed if both systems are running Win 7 and want to use Homegroups. Workgroups will work fine without it.

Sorry... I didnt explain clearly.. I haven't hooked up the new pc yet, I only have the laptop available currently. I was just going to prepare for the networking.. I expect to use homegroups when I do the networking. I accidently deleted the teredo device on the laptop and want to get it back.
They will both be running window 7 home premium.


thanks

Ok, well as the standard fix didn't work for you, I've basically got 3 options for you:

1) Try running the Homegroup Troubleshooter (Under Network Sharing Centre) that may fix it.
2) Try a Repair Install: Repair Install
3) if that doesn't work, I would back everything up and then do a Clean Install: Custom Install Windows 7

You could try the procedure below to reinstall teredo and get IPv6 protocol working again.

Teredo Tunneling Pseudo-Interface Reinstalling in Windows 7

1. Temporarily disable Firewall and third party antivirus program on the computer for a test.

2. To verify relevant services..

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. Scroll down and navigate to the following service. Right click the "Peer Networking Grouping" service and choose Properties.
c. Please check if the service is started; if not, click the Start button and see if it works.
d. You may also choose Automatic next to Startup type.
e. Click OK.
f. Please repeat the above steps with another service: PNRP Machine Name Publication Service.

3. Modify IPv6 registry key to enable IPV6
==========================
a. Click Start, type regedit in Search Bar, and then click regedit in the Programs list.

Note: If you are prompted for an administrator password or confirmation, type your password or click Continue.

b. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\TCPIP6\Parameters

c. Check whether the "DisabledComponents" registry key exists. If so, let's move on the next steps.

d. Double click the "DisabledComponents" registry key and modify the value to 0.

(If the key doesn't exist, please create the key named "DisabledComponents" without the quotes, above and assign the value 0)

e. Exit Registry Editor, and then restart the computer.

Chev65.. So I followed your instructions and the disabledcomponents key existed and I modified it to the 0 value. I restarted the pc and the teredo device still wasn't there. In addition, the value in the disabledcomponents reverted back to "ff".

any other suggestions before I do a re-install of the os?

Btw, Martin. my system is an oem so I don't have the original media for a repair install unless you can help me figure out how to do it without the media

thanks
