What error does it give you?  

Are you assigning the IP address manually?  
Are you certain there isn't another machine on the network with that address?  
Are you sure that address is valid on the network?  

Have you tried a different network cable?  
Have you tried a different port in your switch/router?

Dear paulmacd:
it shows yelllow mark on the network sign .and shows no internet access .
i have confirmed that there is no other machine with same ip address
yes address is valid on network

yes i tried different cable too
yes i tried difefrent port also

this problem is not certain as if i put pc on DHCP it works properly and once if i disable and enable network card it works for some time properly and gives the same yellow mark and shows no internet access .

"its happeneing with all windows 7 pc's when i freshly installed them . later they got corrected themselfs . i dont understand what issue is this "
My question is, what are the networking settings when you "fresly install" them?  I suspect the information is wrong and I'm wondering what settings you use.  What's the result of an IPCONFIG /ALL command on one of these machines?

For me, I often have to disable IPv6 and run a tool called 6to4 remover (http://www.ryanvictory.com/posts/automating-6to4-adapter-removal-in-windows/) to restore network access to some Windows 7 workstations and Windows Server 2008.  Our DC's are still running Windows Server 2003 so that was our reason on why these network settings have to be tweaked to keep it from going haywire.

When you assign an IP address, is it in the range of IP addresses your DHCP server hands out?  If so, it's likely there's another computer on the network with the same IP address.

When the exclamation point appears, try pinging 127.0.0.1 and also try pinging the default gateway address.  Let us know what the results were and we may be able to advise further.

Another good test (when the error is present) would be to go to a different (call it "good") computer on the net and ping the IP address of the problem computer.  Then disconnect the network cable on the problem computer and ping it again (from the good computer).  Those results would be useful here.

It would  also be useful to see the exact results that ipconfig /all produces, as Paulmacd requested.
