How to get rid of “not available web” issue in MS FrontPage?

Hey everyone,
I am posting here for the first time. I have to commit that I am desperate for help! I have got Intel Pentium (4) 1.8 GHz processor. My operating system is Windows XP.
I have got myself stuck in an issue while using MS FrontPage 2000. Here is the issue, whenever I try to open my webpage via FrontPage I get an error message as “The folder you are searching is not accessible.
Folder might be password protected or located on a volume which is not available.” This error appears only when I try to access my web with FrontPage, but I can access website via internet explorer etc.
I have checked that website is OK, and no other computer is having such a problem,and my PC is exclusively irritating me with this issue. But, I am unable to figure out this problem, To fix this issue, I've tried reinstalling FrontPage for almost five times but that doesn't work.
I also have checked my whole firewall settings, and they also seem to be fine. And yes, I have tried searched the support on Microsoft.com knowledge based and tried everything there.
Well, I am totally stumped and frustrated due to this issue and need some help.
I need to know How to get rid of “not available web” issue in MS FrontPage?
I would really appreciate any help.
