In the past month I've had to uninstall/install NIS 2011 3 times due it not work with the error 3043.1 coming up.
Twice I've had to connect to Norton chat support and have an analyst work with me to check the issue and reinstall and again had to do it myself once.
It always displays the same error, that Instrusion Prevention and browser protection are offline and cannot be fixed.
I am happy the analysts are quick to help, but it is frustrating that the files seem to become corrupt so often.
Any ideas? Would the fact I use a wireless router be the problem??
