When I try to open internet explorer, it tells me web site found waiting for reply but the page never loads, and a little box pops up and tells me that the windows task manager has been locked by the administrater. How can I fix this problem?

The best advice I can give to you is not to fix it, but install Mozilla Firefox!!
