Hello everyone, I hope someone can shed light on this very vexing problem. My cousin owns a business and has a PC based surveillance system that runs on Windows XP Home. She was having problems with employees getting on the PC (foolishly the PC is not located in an area where only she could have access to it) and surfing the web and the resulting mess with viruses and spyware left her system crippled. SO she called the vendor of the surveillance system. He came and cleaned up the spyware and then did something to disable web browsing on the PC. The network connection is still active, and she is able to use a VNC app to get into the PC remotely. Neither IS nor Firefox work. In IE no matter what page is requested, a DNS error comes up. It matters not whether the IP and DNS addresses are entered into the system or whether its set to obtain these automatically. Thus if she clicks on the connection icon and goes to the Support tab and clicks on Details, no DNS addresses are visible. Now however, she wants to enable browsing so that she can update Windows as well as the surveillance application. I have been trying to help her undo whatever the vendor did. However I have had no luck so far. I compared services that were active on a PC that has no problems accessing the Web from the same network, to services on the surveillance PC, and enabled those services which had been disabled, so that both PCs have the same services running. Unfortunately, the vendor is no longer in business and cannot be found. I tried googling for ways to disable web-browsing but nothing useful comes up. The only thing I can think of is that he changed some values in the registry, perhaps the port numbers associated with web-browsing? But then what would prevent the PC from being able to get DNS addresses from the router? Its not the router because other PCs on the LAN work normally. I'm stumped. Any ideas??
