Here is the issue: I have a network at my business with 7 computers on it. 1 computer is wried to the router (LInksys) and the other 6 are wireless. 5 of the wireless get an address from the router with no problem, but there is one computer that will not obtain an IP address. When I go to IPCONFIG, it says it is trying to get an address that is already on the network. The router is set to give addresses to 50 computers, so I can't imagine the problem. Moreover, if I manually assign an IP and put in the DNS servers, it gets on with no problem. This is a pain, because my ISP uses DHCP, so I have to keep changing the DNS servers. How do I get my computer t ostop giving my headaches??????? Thanks in advance.

Does your ISP really change it's DNS addresses? I kind of doubt it does. You should call them and ask and if they don't, statically assign your IP settings to the problem PC.

Why don't you try giving that one computer a static I.P. it will probably work Thank me by visiting my http://masterjuan0101.googlepages.com

I would give all the wireless workstations static IP addresses. That protects you from wardrivers.

There's something funky here. Sounds like the router is attempting to assign an ip address that a statically configured device is already using, i.e., a network printer, access point, etc. If so, you might want to change that device to something like x.x.x.100 so it's outside the range being assigned by the router--just make sure it's in the subnet mask's range--or set it to receive its network config dynamically. Anyhoo, a quick workaround is to statically assign an IP address to the problem computer and use the router's LAN IP address as the DNS server. As long as the router knows where your ISP's DNS servers are, it will relay DNS requests. "If it ain't broke, upgrade anyway."
