What does network 6to4 adapter code 10 error refers to

[LAMONT D]

I am not able to access internet on my system. It is a Vista computer. There is some Network 6 to 4 adapter which is installed in Device Manager. I keep my system updated with new drivers. But some this is not working. I check the status and found some error code 10. I am a bit confused to understand what is actually going on here. My internet stopped working. I need some help here to troubleshoot the same. Thanks.

I am too having the same issue. I am not able to get my system working. I am having a cable connection. I do not understand from where this 6 to 4 adapter appeared. I tried to run system update but nothing helped. I purchased a modem and hooked that to the system. Things went back to fine.
