Must renew ip after each bootup

[webcaster]

About a week ago, I discovered I must renew my ip address (ipconfig /renew) after each bootup, or else I cannot connect to the Internet. I put the ipconfig command in the startup directory so this takes place automatically, but I'm wondering why this happened in the first place.

The only change I made in my pc was to get VPN access to our network at the office, and the lack of connection applies to that, too, unless I renew.

I'm using WinXP Home, a Linksys BEFW11S4 router, and a Toshiba cable modem.

The other PCs in my home use wireless networking, and do not have this problem.

Any suggestions for troubleshooting??

Many thanks.

Try this:
1. Control Panel > Network Connections
2. Choose the adapter that you are using, right-click and Properties
3. Under the heading "This connection uses the following items" click "Internet Protocol (TCP/IP)" (don't uncheck this item, only click it so that it's selected)
4. Then click properties underneath and to the right of that.
5. Make sure all the options are about obtaining the stuff automatically. Same with the other tab as well.

Let me know if this helped.
