First from a command prompt type ipconfig /renew to see if it gets an address.  do an ipconfig /all afterwards to see.

I used:  192.168.1.150 255.255.255.0 192.168.1.1 4.2.2.1 ran cmd ipconfig /all:  rec'd the exact info  as above:

If uou right-click on My Network Places. select to properties, there should be only one Local Area Connection.  Right-Click on it and select properties.  In the 'This Connection Uses the Folowing Properties:' box, elevator down and select Internet Properties.  Is the IP Address set to  192.168.1.150 and the Subnet mask set to 255.255.255.0.  The gateway is set to 192.168.1.1 and DNS set to 4.2.2.1 and when you do an ipconfig /all everything is still set to 0.0.0.0?

If you still had 0.0.0.0 after specifying a static IP, you don't have any network connectivity to be recognized by your system.  How is your system connect to the Intnernet?  Please specifying each piece of gear and supplier.  What lights are on the equipment and which are on and which are off?

If you are hard-wired, is it possible you have the card plugged into a crossover (or uplink) on your hub/switch?  Or is it possible you are using a crossover cable or bad cable?

I have no internet or network connection on the machine in question. I have tried new cables, even tried to setup a wireless connection, nothing works.  Removed card, reinstalled, removed card installed new card.  All still the same.

It doesnt appear that there is a hardware problem in your computer.  The problem must be with the connection itself (external to your computer).  What type of connection is this? For example, a LAN connection (connecting to a network that has an internet connection), a DSL, a cable connection?  If you have a router or any type of modem please specify that.

I have hooked up via a cable connection, via a DSL, and via a T-1, through a router, through a direct connect, through a wireless.  There is no connection to anything!

Do you get a link light on the netork card and what it is connected to?

I get one blinking light, it is trying to get an IP address.  It never gets one so I all I get is the one light never the two.

Has this desktop ever been connected to the Internet or network?  It should get a link light even if it doesn't have an IP address.  The link light is a physical hardware level indicator.  If it doesn't het a link light it, the only thing that should cause that is speed or duplex.

It has always been connected to the internet and a network until last week when this issue appeared.  Agasin, I get one light, and a continual indication looking for a connection

When I hook up a wireless, it never sees the wireless network?

First you said:
"I get one blinking light, it is trying to get an IP address.  It never gets one so I all I get is the one light never the two."
Then you said:
"It has always been connected to the internet and a network until last week when this issue appeared.  Agasin, I get one light, and a continual indication looking for a connection."

The link light should be on solid if you are connected to a hub, a switch, or another PC with a crossover cable.  Nothing else even needs to be there.  It is a hardware level indicator.  It has nothing to do with IP address or connectivity to anything but the physical device it is connected to.

It sounds to me like you have been infected with a virus or some other form of malware.  You are going to need to boot to safe mode and run a virus scanner and an anti-spyware scanner.  Firewalls do not stop viruses, spyware or malware.  You may need to do a reinstall of your OS.

I just went to network connections and properties, on authentication tab those areas are grayed out, cannot access.

Either a Group or Local security policy is in force, you are not logged in as administrator, or you system is infected.  What Anti-Virus are you running?  Is it up to date with the most current pattern files?  What Anti-Spyware are you running?  Is it up to date with the most current pattern files?

You may need to do a reinstall of your OS.  If you have enoght space, you could do a parallel install and see if it resolves your communication problems.  If it does, install your antivirus and anti-spyware applications, scan the system, and then (and ONLY then) copy your old Documents and Settings folder over (all your data) and re-install your apps.
