I have a client with Win XP Pro on a p2p network. They went to lunch and when they came back, they could no longer get on the internet, "page cannot be displayed." I found by pinging I still got replies from google.com. Checking in Task Manager process, I found (2) winlogon.exe running. I logged the person off and then back on. This got rid of the extra winlogon.exe and was able to get web pages to display, however this lasted on 3-5 minutes, then back to (2) winlogon.exe.

Started the system up in safe mode w/networking and did not have a problem. Ran spyware removers and housecall, the system came back clean. I am at a loss. Any suggestions????
