So I didn't care for OneCare, but does it have to keep my computer locked down AFTER it is uninstalled?  Finally got it completely uninstalled ...

This was more than a little frustrating.  After uninstalling OneCare I could not access or be accessed by other computers on my home network.  My setup worked fine before OneCare and I was able to get it working with OneCare installed on a couple computers.  Once I uninstalled OneCare, suddenly I couldn't access these computers or be accessed by them.  Changing XP SP2 firewall settings did nothing.  I finally figured out that during the OneCare install, something called Microsoft Protection Services was installed with a seperate MSI file from the OneCare Program Files directory.  Apparently it was not removed during the uninstall.  It also did not appear in Add/Remove Programs on my computer (a special setting that can be done for any MSI installed package).

Once I uninstalled this program, everything worked fine.  If you are having similar troubles, try running the below command line as and admin - be careful you machine will automatically start rebooting.

MSIEXEC /X {5A03BEC5-E6E3-4751-ADC0-CDD271414536}
