Need more info regarding the structure of the network.
Is it happening to all clients, a few clients, or just one?

has the DHCP server been authorized?
If it is only one client... check cabling... nic....tcp/ip....
If it is all the clients ....check the server.... settings and authorizing
If a select few......what do they have in common? ....a routermaybe....

If just this machine, check the cable and NIC first (eliminate the physical layer as the issue) If those are fine (swap them out for known good ones)
make sure all firewalls are off
then try resetting the tcp stack;en-us;Q299357
How to Reset Internet Protocol (TCP/IP) in Windows XP

View products that this article applies to.

This article was previously published under Q299357

For a Microsoft Windows Server 2003 version of this article, see 317518.


When viewing the list of components for a network interface, you may notice that the Uninstall button is disabled when Internet Protocol (TCP/IP) is selected. In Windows XP, the TCP/IP stack is considered a core component of the operating system; therefore, it is not possible to uninstall TCP/IP in Windows XP.

In extreme cases, reinstalling the Internet Protocol stack may be the most appropriate solution. With the NetShell utility, you can now reset the TCP/IP stack back to a pristine state, to the same state as when the operating system was installed.


The NetShell utility (netsh) is a command-line scripting interface for the configuring and monitoring of Windows XP networking. This tool provides an interactive network shell interface to the user.

In Windows XP, a reset command is available in the IP context of the NetShell utility. When this command is executed, it rewrites pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to achieve the same result as the removal and the reinstallation of the protocol.




Command Usage

netsh int ip reset [log_file_name]

To successfully execute the command, you must specify a log file name where actions taken by netsh will be recorded. For example, typing either of the examples that are listed in the "Command Samples" section later in this article at a command prompt would reset the TCP/IP stack on a system and record the actions that were taken in the log file, Resetlog.txt. The first sample creates the log file in the current directory, while the second sample demonstrates the use of a path where the log will be created. In either case, where the specified log file already exists, the new log will be appended to the end of the existing file.

Command Samples

netsh int ip reset resetlog.txt

netsh int ip reset c:\resetlog.txt

Sample Log File for NETSH INT IP RESET

The following is a sample of the log file that is generated by netsh when an IP reset command is issued. The actual log file may vary depending on the configuration of the system on which the command is issued. In some cases, there may be no actions logged in the file, which typically is the case when the TCP/IP registry keys have not been altered from their original configuration.

Had to point the Install to the "nettcpip.inf" in the windows/inf directory. That allows TCP/IP to install over the top of the TCP/IP required for operation of Windows XP.
