Hi everyone,
I'm in IT, and my organization has about 20 or so Dell Optiplex 740 and 745, plus a Dell Server that all have the Broadcom NetXtreme 57xx network controller. All these machines have this random problem. The computer boots up, internet and connections are good, then randomly throuhout using the computer, the internet dies. Tried doing some troubleshooting and can't get anywhere because everything seems to be frozen that has to deal with the network settings/services.
Here is a list of the symptoms when this occurs:
1.Tried disabling the network adapter through Network Connections, but explorer froze. After restarting explorer, the adapter shows as disabled. When I try enabling it, I get the message 3 seconds later "Connection Failed!" and the adapter stays disabled.
2.Can't disable or enable the network adapter through Device Manager. Explorer freezes if an attempt is made
3.ipconfig /all returns "Windows IP configuration" and nothing else
4.ipconfig /release returns "Windows IP configuration The operation failed as no adapter is in the state permissible for this operation"
5. Tried restarting every service. They start back up with no errors or freezing, but the adapter still won't respond.
