I asked this question in the "Netwworking, Mail..." Forum and it was suggested that I post here.
I think this is a somewhat frequent problem but I can't determine the best course of action.
After running for some time in a very stable state with XP sp2 I purchased Office 2010 which apparently will only install with sp3.
I installed sp3 and immediately had problems. I could not get online and when I attempted to turn on Windows firewall I got the message "windows cannot start the windows firewall/internet connection sharing (ICS) service"
It was suggested to me in the other forum that my security software was a potential source of the problem. I used system restore to go back to the pre-sp3 configuration and uninstalled my security software. I checked - Windows firewall turned on, online access was available.
I then downloaded the sp3 install .exe and installed. I have the same problem as before. I tried other approaches to turning on Windows Firewall. The various error messages were essentially the same, although one included "Error 1068: The dependency service or group failed to start." Don't know if that provides any additional information or not.
I'm dead in the water. I just spent $400 on Office 2010 - which I need - but I can't get from sp2 to a clean sp3 install.
Any and all help is greatly appreciated!!
