Hi everyone, I am new to this site and don't know a great deal about computers. I am searching for help with a problem. I have two computers networked in my home through a linksys wireless router and a cable modem. I was on the internet on my main computer and was shut down for some reason. I was able to reboot but started receiving error messages about a disk problem. I tried to run my Norton disk doctor but discovered that I suddenly do not have access to my C drive. The Norton message advised that I check my computers secuity settings. I was ony able to do that in safe boot because that is the only way I can access or change any settings on my C drive. While I am in safe boot I am shown as administrator on everything I can find but when I reboot into normal mode, I am again denied access to the C drive. I am able to access the internet and my email but cannot open any attachments. I feel (but could easily be wrong) the problem is in my network settings. Can anyone give any advise. I am operating on Windows XP Home edition. Thanks.
