Unidentified Network, No Internet Access In Windows 2008 R2 Server

[syampydimarri86]

I am using windows 2008 server R2 Enterprise_x64 bit OS installed.I am facing a strange issue like unidentified network & no internet access in windows 2008 r2 which worked fine till last night. And tried in all the ways by changing the patch cord and even tried assigning different IP's which did not work but the same public IP's are working fine if i configure them in a different system or server. But if i configure a private Ip in the series of 192.168.1.1 or something like this i am able to browse for internet but can not access internet using public IP's, tried disabling firewall and even there is no router in between the server Can any one help me out in this.
thx in advance.

Questions:
"But if i configure a private Ip in the series of 192.168.1.1 or something like this i am able to browse for internet but can not access internet using public IP's"

If you set a PRIVATE IP to your server you can SURF ON INTERNET? And if you set a PUBLIC IP to your server YOU CANNOT SURF, right?

" there is no router in between the server"

That's quite impossible... if you can surf internet with a PRIVATE address there's something somewhere that gives you a public ip.


Are you sure that nobody is using your public IP?
Can you provide a network diagram?
