Original Title: Error 12007 in XP.We had a virus infection a couple of months ago. The virus caused a lot of damage so I had to repair the XP installation. However, little problems accumulated to the point that I decided to make a new installation. Re-formated the bootable HD and started re-installing software. After installing E8, the error 12007 showed up and I lost the internet connection. Initially, I would be able to restore the connection by uninstalling the NIC and re-installing upon rebooting; but later I couldn't restore it at all!There is always the question if the virus is still present in the system. The computer have 2 HD and I moved data that we did not want lost into the non-bootable one. I did all these after scanning the whole system (I have the Panda Internet security program as AV) which resulted in a clean pass. I repeated the scan after the new XP installation before connecting to the web or installing software with the assurance that the computer was clean.After looking into microsoft support and this forum I tried several of the recommendation given to other with similar problems such as disabling the Bonjour service, upgrading the ethernet drivers (in the motherboard), installing a PCI NIC, and of course, going through the internet and network setups around a thousand times.What else can I do short of go back to install XP from the begining?Thank you for your helpVictoreme
