Hello, i am generally a pc freak so I am a bit shocked that I am stuck for once basically I mess around with msconfig alot but when I install xp sp3 I cannot connect to the internet unless i'm on safe mode like now!
please help I had similar problem but finally figured it out.
Fortunately, depending on the change that was made, it is sometimes possible to return Windows to a functional state with minimal effort.
Not coincidentally, Microsoft offers a tool that does just this, the Files and Settings Transfer Wizard.
But this tool will only restore your backup to an XP box, so it might be better to use a traditional backup program for this just in case.
My issue was with Windows Zero Configuration Service after install of SP3.
Just had to restart the service manually from control panel and BOOM, internet works.
