Scope not working




I have just installed Win2003 x32 and installed DHCP. Also i created a sope and activated it. But now my client will not get the range of the scope created. What could be the problem?

Also, i recreated the scope another time to see if i had done something wrong and still the same result.

Please let me know.

Thank you,


The first thing I would suggest is checking if there is an unauthorised DHCP server running on the network. It can be quite surprising what equipment can act as a DHCP server. A simple way to check is to disable the DHCP server service on your Windows 2003 server and renew the IP address on a PC. If the IP renews successfully, then there is a DHCP server running on another device that needs to be disabled.

If this happens, here’s a couple of things to check:

[li]Make sure DHCP is disabled on your router.
[/li][li]If you have any Wi-Fi access points, check their configuration, as some Wi-Fi access points have a built-in DHCP server on by default.
[/li][li]Windows XP has its own DHCP server built-in, which can be activated if a PC is used to let’s say share a USB modem (cable, satellite, etc.) over the network. So make sure “Internet Connection Sharing” is disabled on PCs and especially laptops.

If the IP fails to renew after the DHCP service is disabled, enable it again and try the following on an affected PC: Open a command prompt and type in “ipconfig /release” to force it to release its previous info it got from the DHCP server, then type in “ipconfig /renew”.


Connect a switch between server and client, no other connections whatsoever (no other clients, no other networks, etc). Check dhcp again.

If client dhcp fails again try:

ipconfig /release
ipconfig /flushdns
ipconfig /registerdns
ipconfig /renew


It worked. Thank you.
