Dear Rick, Yes, I did install them in the order suggested. However, after reading your post, I revisited the subject and reinstalled first the chipset driver and then the DSS and then also reinstalled the NIC driver. This worked.  So, thank you very much for your help. Regards, Thoughtful123
I have just reinstalled Windows XP Home edition from the reinstallation disk on a Dell Dimension 4500. I installed all the updates, through Service Pack 2 and Service Pack 3 and subsequent. Everything seems to be working well but the Device Manager does not see the Ethernet Controller.  The NIC is an Intel PRO /100 M Ethernet Adaptor but the Device Manager does not see it.  I was careful to install the drivers in the order shown in the Dell help link on the Dell Drivers Downloads website. In fact, I installed them a second time to make sure that I had the correct order. I would appreciate any help in learning what I am doing wrong.  Thanks. Thoughtful123
