Access Denied: Renewing Adapter

Dear AO,

I seached the forums and had no luck finding anything about this topic. I work in a computer service shop. Lately I've had a large amount of computers come in with a network problem. When I go to release and renew the IP address I get an error "Access Denied: Renewing Adapter" I've tried:

1) Updating Network Drivers
2) Uninstalling any/all Antivirus and Firewall software (if any)
3) Removing and re-installing network drivers
4) Scanning and Removing spyware using: Spybot, Ad-aware, and TZ (fully updated)
5) Scanning and Removing viruses (if any)
6) Performing all Windows updates
7) Winsock fix file that I found on a website for download

Note: I've had this problem with Windows 98 and Windows XP

I've found one temporary solution which involves replacing the NIC with a new one. This solves the problem but recently I've had a computer that when I replaced the NIC the same "Access Denied: Renewing Adapter" still occured.

Please help if you have any advice or if you know where to find good solutions for the problem.

Thanks :)

There are hundreds of problems that would produce this error message, ranging from viruses to faulty switches. Given the fact that you've reinstalled network drivers and NIX cards on some, might I suggest the idea that your shop's setup (either hardware or software) is somehow causing the problem? Maybe try static addresses as a start also?

Solution: A technician I work with found the solution today. When plugging in static IP addresses the network cards worked so this led us to suspect the routers auto assignment. We hard reset the linksys BEFSR41 Router and updated the firmware. Everything is working perfectly.
