Re: Vista can't see the network

I am helping out a friend with her computer. It has Vista x64 SP1. The computer had been infected by some malicious software and it did not boot at all. After some tinkering I managed to get into safe mode and run MBAM. The computer eventually booted, but had no desktop. I went into the Task manager and saw that there was no Explorer process, so I started it and al was well. I then booted from the OS disc included with the PC, got into the repair screen that had sustem restore and restored the PC to a date before it got infected. This worked well and now the PC boot into Vista without any problems. I ran an antivirus and MBAM and neither detected any malware.

I thought all was well until I tried to connect to the Internet. I have cable service, a modem connected to a router and the PCs connected to the router. The Vista installation would not see anything out there, I tinkered and managed to get a message that said that there was "limited connectivity available". I figured that the LAN card's driver had been corrupted so I downloaded the driver and installed it. The installation was successful, but the problem persisted. I then went into Dev. manager and went into the card's properties. The status comment indicated that the device was working correctly. I noticed that there was another LAN device under the Network. It was the MS 6to 4 Adapter and there was anexclamation point next to it. I went into its properties and the remark indicated code 31.

I did not know what this 6 to 4 adapter was so I investigated. It seems that it is only a translator so that IPv6 can work with IPv4. So this took me back to the card's properties to see what protocols were binded to it. Lo and behold, it had both IP4 and IP6. I figured that the problem with the adapter could be fixed by uninstalling it and then reinstaling it. I proceeded to do this, but found that I could not re-install the 6 to 4 adapter. I went into Dev. Manager, used the Add legacy hardware option and the process went well and finished successfully, but the adapter never reappeared in dev. manager. After trying to clean the registry and not being able to solve this problem I figured I could do a repair installation as I have done with Win XP, but this option was not readily available within the Vista setup process. After doing some research, it seems that an upgrade install could solve my problem. I proceeded with it. All went well until it got to the Completing upgrade stage. It seemed that the PC was frozen. Hopeful, I left it running all night. In the morning there was a message indicating that the upgrade had failed and that the previous install would be restored. Although it took some time, Vista was restored. Since the install DVD had Vista SP1, I figured that perhaps SP2 had been installed (I was not even sure there was an SP2!). I check the system's properties which indicated that it was Vista SP1, so I have no idea why the upgrade install failed, unless it only works with previous versions of Windows, which does not make sense since this DVD is supposed to be used to restore a damaged installation.

I examined the hard drive and found that it has a recovery partition. I tried to explore that partition to locate some information and/or executable that would start the recovery, but the partition was not accessible, saying that it was being protected by PC angel. I did some research on the 'net but was not able to find anything. I then went into system restore and went back to a restore point before I uninstalled the 6 to 4 MS adapter. I was not able to locate any information that told me how to solve this problem. I started to suspect the hardware, thinking that it could be the LAN adapter, so I booted the PC with a linux distro and tested. It connected perfectly to the Internet and I was able to navigate to different Web sites. It was confirned, this is a Windows Vista problem.

I also searched for the 6to 4 adapter and found some download sites, but most were dated around 2004 and decided to not take that path. So now, after all this background, my question is: what can I do to solve this connectivity problem? While the 6 to 4 adapter was uninstalled I unchecked the IPv6 protocol in the card's properties, but this did not have any effect. Any ideas or suggestions are greatly appreciated, as I have tried everything I could think of and now need a different pair of eyes on this. Perhaps I am missing a simple solution. Thank you for reading this long post. Hopefully I have provided enough info so that some one can suggest something. Best wishes to all! Saga



You know the bigger problem you have is that it is impossible to know what all else has been corrupted and to be honest I think you'd have been better to bite the bullet and do a clean install.

What do you get if you run>cmd and then ipconfig /all ?

Are any services listed disabled? DHCP client?
