Help...Site Access Issue

[marvc]

I need some help trying to pinpoint a problem I'm having with my site (http://www.nubiint.com). I'm getting claims from some of my test users that they cannot access the site stating that they get an error that the site isn't available.
This is a w2k server running phphome w/Apache, mysql, and php that I'm hosting.
Any help is appreciated..
