Hello, any info you can provide is greatly appreciated. Windows XP with Service Pack 3 I have no network connectivity. When I go to Start, Run, "cmd", and type "ipconfig/all" at the command prompt, no ip information is returned. Only the text "Windows IP Configuration" is returned. ipconfig.exe and ipconf.tsp both exist at C:\WINDOWS\system32 I tried replacing both without success. I also ran the NetShell utility (netsh)to reset TCP/IP without success http://support.microsoft.com/defaul... No antivirus software or firewalls running. Why am I unable to pull up any ip information?

Try here->http://www.microsoft.com/windowsxp/using/networking/maintain/troubleshoot.mspx

nothing wrong with what ipconfig told you. You should put the original files back. your tcp/lp stack is corrupted. this should help http://support.microsoft.com/kb/299357

puertoboricua... thanks but that doesn't address the issue. wanderer... thanks but as stated in my post I already followed those steps to reset TCP/IP and address any stack corruption.

please post the results of an ipconfig /all any thing in event viewer? device manager show nic as ok? virus/spyware free? chkdsk clean? what are you connected to that will give you a dhcp address? Just goes to show you speed reading doesn't always give you all the facts. I neglected to read the last three sentences. :-)
