Here is a quick rundown of the problem. 1. Dell Dimension 4600 will not obtain IP in auto. 2. I can assign it one manually like 192.168.0.5 and give it the DNS Server info. I then can go and enable it to obtain an IP and it will do that and all is well. Internet works fine. Until!! I reboot and then it loses it IP. Any suggestions will be great. 3. Have another pc hooked up and running from the same router and no problems. 4. check cables 5. Changed NIC both have same problem. 6. rebooted 1000 times.

First of all this is quite a common problem, but if you give us more information such as answers to the questions below, we might be able to help you better. Which router do you have (brand+model)? Have you checked in your router configuration pages, whether obtain IP by DCHP is selected? Have you tried disabling your firewall? (if you have one) Do you have an installation CD that came with the router? How is your PC connected to the router? (ethernet cable/USB?)

Thanks ER4S3R for your respnse. To answer your questions Router is working fine with other computers No Firewalls Virsus Scanners etc Now here was the kicker after six hours of hunting down this problem I found that the DHCP Client was stopped. That explains why I could manually config this card but not enable it to automatically obtain an IP address. I found the DHCP Client by going to Control Panel-Performance and Maintenance-Admin Tools-Services. Scrolled down to DHCP Client Selected Properties and Selected Automatic for Startup Type. Problem Solved. I just wonder what turned this off in the first place? Anyway again thanks for you help.

Nice to hear you've solved the problem, well done. Sometimes it's the simplest things that takes ages to figure out. Θ ER4S3R Θ Beware of computer programmers that carry screwdrivers.
