I just update the Windows Service Pack 2. Prior to that I ran Spybot Search and Destroy, with no Spyware found. I also scanned using Norton Antivirus. I finally made a restore point. After installing the service pack, the service pack does not recognize my Antivirus. I have read about that issue. My ? is that I can't access a folder on my H Drive (200 gig WD Hard drive). I get a Windows Explorer has encountered a problem. Error Signiture Appname: Explorer.exe Mod Ver 5.1.2600.1217 Appver 6.0.2800.1221 offset 000096cf Modname: ntdll.dll I tried to use system restore and it states that it was unable to restore to my designated retore point. I have had this issue (not being able to restore a previously save point) for quite a while, and was wondering if anyone has had this problem. I will attempt to uninstall the service pack a reinstall in a few days, but I would like to see if anyone has a recommendation prior to me doing this.
