Web Servers Default Page Error

[emrey]

Hi,

Few day ago, I buy new server and install Plesk Panel 11 for Windows on Server 2008 R2 op. system. I can easly install and set all parameters. I do not understand why, but somehow I have a problem.

First Problem:
Some times my web site works correctly, but some times Web Servers Default page comes. I try to determine that, when Web Servers Default page comes, ping result to ns2.beybilgisayar.net. When I flushdns my machine, ping result change to ns1.beybilgisayar.net,

Second Problem:
Site works with "www", but without "www" Web Servers Default page comes.

May be it can be about DNS setting. My DNS setting below here,

213.232.33.234 / 24 PTR <domain>.
<domain>. NS ns2.beybilgisayar.net.
<domain>. NS ns1.beybilgisayar.net.
<domain>. A 213.232.33.234
