Hi everyone,
I am having a problem getting my desktop pc to accept an IP from my modem.  I have tried using ipconfig/release then ipconfig/renew to no avail.  I get an error message saying there is an issue with the DHCP server.  I am using Vista.  I have verified the modem is working as I am directly connected to it right now using my wife's Macbook Pro.  Any help would be greatly appredicated!  Thanks!Full error, please.Sure, it SAYS:
"An error occurred while renewing interface Primary Connection : unable to contact your DHCP server. Request has timed out."

"Primary Connection" is what I named my Local Area Connection 1.Anyone have an idea?  This is driving me nuts!!! At command prompt, type in:
ipconfig /all
Hit Enter.

Copy everything, and post it back.Microsoft Windows [Version 6.0.6001]

That's all of it.  Suffice it to say, thank god for flash drives.  I had started out typing it all since I couldn't email it and was thinking, "Man, I really wish floppy disks were still popular." till I remembered the Flash Drives that have replaced them. 
 Try WinsockFix: http://www.tacktech.com/display.cfm?ttid=257
Obviously, you have to get it from working computer.When I run WinSockFix I get a message saying "Registry Import Information not Found".  It then continues running and at the end it says "Repair Completed Please Reboot".  When I hit OK, it says "Run-time error '53': FILE Not Found".  I still tried rebooting but it didn't change anything.   One more try...
At Command Prompt, type in:
netsh int ip reset
Hit Enter.
Restart computer, and see, if it helped.Same thing, same IP address.  Should I just do a fresh install?  /bummed outYeah, something wrong here.
Are you the lucky (one of a few) OWNER of Vista DVD?
Sure am, made sure to order that when I bought vista.Then, you have some repair options, listed here: http://www.bleepingcomputer.com/tutorials/tutorial148.html
BTW...have the connection ever worked?Yea, it worked all the way till last night when i...GASP...updated windows....In that case, you may try System Restore.
