can't renew IP

Hi,
I just set up a development server, (windows server 2003) on a laptop. For
political/security reasons I have to be a DHCP client on the customer's LAN.
The problem is, I can't renew the address.. I can't even ping the DHCP
server (or the internet). It did work a couple days ago, before a colleague
tried to install stuff. He put on MSSQL server (and Project Server and
SharePoint, but I disabled them because he didn't get them to work). The
cable and card and driver seem to be working, green lights all around. When
I configure a static IP, using info from another workstation on the LAN,
both computers complain about the IP conflict. So I do exist on the LAN. I
can't see my server from my workstation through MSExplorer. And the server
still can't get a response from any other host. Loopback ping works fine. I
tried disabling DNS service and DHCP service (not client) just for grins,
but they weren't configured anyway. Although the Network Adaptor driver is
okay, the Network Controller and PCI and Multimedia/Audio are not working,
according to device manager. I don't like it, but it wasn't preventing me
from connecting to the network before so I wasn't worried about it just yet.
help...
Thanks in advance

SV,

What does an IPCONFIG /ALL tell you? Are you set up for DHCP and are you configured with an APIPA Address (169.254.x.x)? If you configure this
server with an IP Address that is not being used by another client (try to ping for a few IPs and use the one that does not reply). Do you have full network
connectivity?

Are you on a separate broadcast domains, i.e. DHCP is broadcast based so is the DHCP Discover sent from your system making it to the DHCP
Server? Do you have the Internet Connection Firewall enabled on this NIC? How about other Security suites on this system, Zone Alarm, Notron, ETC?

The best information here is to install network monitor on this system and then to trace the ipconfig /release and ipconfig /renew traffic sent from the
system.
