can you please check if your DHCP Client at services is Started and Automatic?
Next question is from the DHCP server, what is the scope of the IP that is allocated? is it enough to be used by your network?
You need to provide a little more info about this issue.
- Do you have free leases to allocate in the scope this specific client is in? (Check event log on the server to see if there is any messages related)
- Do you have some kind of MAC address filtering in place (<a href=”http://blogs.technet.com/b/teamdhcp/archive/2007/10/03/dhcp-server-callout-dll-for-mac-address-based-filtering.aspx”>DHCP Sever Callout DLL</a>)? Since Windows Server 2003 in possible to install a DLL to filter DHCP requests based on MAC address.
- From my experience, it is also possible that an old, corrupted NIC driver can lead to this: a client unable to be delivered an IP address. Check if your NIC drivers are latest version available.
Hope this helps to find whats happening.
