I installed Windows Server 2003 R2 over Windows XP and immediately after installing the OS I have limited or no connectivity regardless of being directly connected or behind a router. It will not renew the IP address. I turned off the Security component for IE and still nothing.

Did you install the mobo chipset? This will allow you to use the hardware that is integrated into system board. Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

Well I am not sure about reinstalling the mobo software because it was a Windows 98 machine so many of the CD are out of the question and the mobo seems fine. All drivers that go with it seemed functional up to XP and still do now. That includes the network card driver.

That's a bit old but if the XP chipset from the manufaturer worked then it might also work for server 2003. It might be easier to just buy a $15 NIC card. http://www.windowsservercatalog.com/ Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

I can replace things but I also installed Server 2003 on a laptop to double check the problem existed there too and it did when connected directly to the wall. Dont ask my why I choose a laptop. So I guess what I am saying is I want to mess around with the settings till it works because I will probably learn something and that seems to be where the problem is.

Ok, sounds good. Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

Anyone have an idea?

Please give the static ip address and check the behaviour ? and also change the duplex settings randomly from the advanced configrations in the network settings please do check and repoer back. Thankshttp://www.virmansec.com/blogs/skhairuddin

Well I can not give it a static IP address. I do not know how to check duplex setting. Isn't there just a setting in the OS for any Server OS, Linux or Microsoft, that causes it to not obtain Internet out of the box that you have to tweak? I am looking for that. I assume with a static IP address a server OS would work fine but in this case I want to have a server computer behind a router. And I already set up a rule for port forwarding in the router so I could set that up if that was a solution, I just need some steps on the computer side. I already disabled the security in IE and I set it to obtain automatically.

Is this a connection at home? Cable, dsl, ??? Sounds like you need to power-cycle your "modem" if it's not leasing an IP address when you are directly connected to it when it's running in bridge mode.Matt W. CCNP, CCDA, CCNA-S, RHCT, MCSE, MCSA, MCP+I, A+

Well I already did a reset to the router. This connection is a home. FiOS.

Have you tried to reinstalling the NIC Driver? I had a similar problem with an old HP Computer, even though the driver installed it would not function correctly.
