Hi Guys,

I have several questions. I am somewhat, an amateur. I have several questions and would really like, if you could answer them accordingly also.

What is the purpose of a server ?

I tried connecting to a remote desktop when Windows gave me an error message popup, displaying a 720 error and the connection could not be established. I tried Help and support center but it was of no use. Any one facing the same problem please let me know.

Network Connections

Cannot connect the phonebook entry.

Error 720: A connection to the remote computer could not be established.  You might need to change the network settings for this connection.  For further assistance, click More Info or search Help and Support Center for this error number.

OK

Could any one please help me with this ?

Hi,

I was browsing my Facebook when I saw a link of a funny video and I clicked it. My page went blank and displayed the message, "HTTP Error 403.6". I closed Internet Explorer, refreshed my page and tried to access my Facebook again. Sadly, I cannot log-in anymore.

Facebook page doesn't load anymore. I tried to research about this problem and I saw this one note saying:

"HTTP Error 403.6" Error Message Occurs When You Try to Access Web Sites Beyond Proxy Server

What exactly does this mean, I have no idea.

Thanks.

My internet connection keeps dropping intermittently.

It started about a month back and still goes on. Resetting my router or taking the Ethernet cable off the PC, corrects the problem but it's very annoying at times.

The connection drops for like, every half an hour or so and then I have to physically correct it. At first, I thought it was a hardware problem so I changed the router and then tried another Ethernet cable but the problem still persists.

I am running Windows Vista Home Premium  on an Intel 965 chipset and have 2GB RAM. My router is provided by my service provider, so I don’t know its make or model.

I planned to realize my small business involving 11 computer units, including the server. The type of my business is internet gaming and savvy. I want to connect all units to the internet, but I don't have an idea in configuring it. I am looking forward to my business and I really need to know what is the ideal configuration. 

All other hardware devices and software applications used in my network are already there. As of now, we are using DHCP to connect to the internet automatically. I can't differentiate from Static because I don't have an idea how to use IP addressing.  What should be the ideal network configuration to use in my business? Please tell me how to do it.

What are private proxies and how it is functioning?

Thank you.

What is DNS? And what are the functions of the DNS?

Guys, I need your help. I am having problems connecting to my Internet connection using my desktop computer.

I am using a cable internet and every time I turn on my computer, I get a yellow triangle on the Internet Access icon, found on the lower right corner.

I have two computers connected on the router and only one computer is experiencing the issue. Please help!
