Trying to install SP4 for Windows 2000 Server from MS Web site. The Windows update does not work (IE 6 will not load except in safe mode) and other issues on this PC. So I obtained the SP4 download using Firefox and started the install wizard. It expanded files and has stopped at the "Updating Your System" screen with the details "Inspecting your current configuration" in the status area. It's been sitting for quite a while. How long should this take? Would like to know if this is normal or if system has hung up. Before starting I scanned for spyware, visruses etc. In safe mode tried to get IE 6 to go to Windows updates but received: "file srequired to use windows update are no longer registered or installed on your computer, to continue-register or reinstall the files not recommended.." Trying to find some way to get IE 6 and other issues resolved. Any suggestion appreciated.
