I just acquired two Gateway e6000 Pentium 4 2.4 Ghz XP PRO machines from work,(put out to pasture). They were setup to login to our domain at work and then after authentication you could access the internet. They were setup to receive an IP address from our domain controller and DNS was controlled by a local server. After bringing them home, I removed them from the domain and created a workgroup. I also set all TCP/IP properties to authenticate automatically and removed all instances for DNS. My current internet connection at home is a Westell Ethernet ADSL Modem C90-36R516 with a Cat5 cable going directly to the NIC. My existing home computer powers up and receives an IP address from the Westell without a problem but when I try attaching either of the Gateways, I get the error listed above. I have spent many hours troubleshooting this problem. I have tried the release/renew command, clearing the IP stack with netsh, checking security policy, clearing IP filtering, plus many, many other things. I was able to establish a connection and get on the internet with a Gateway but only after I gave the new Gateway a fixed IP address, default gateway and DNS entries that matched the current settings of my home computer. Correct me if I am wrong but I think I am issued a different IP by my Westell modem/router every time I boot up my computer. Or does this IP come from my ISP? And if the IP changes with every login, the Gateways will then not be able to login after a shutdown. Any ideas on how to get these two machines to login and receive an IP automatically like my existing home computer? Am I asking the right questions? Did I provide enough information? Thanks in advance for any help.
