Today I was at the home of colleague to make it possible for him to connect from home with his laptop to the company network. At first all went smoothly. The wireless network-adapter was installed within a few minutes. It got a strong and clear signal. And of course the connection was secured.
But strangely enough I could not connect to the company network. Quickly I found out that for some reason the laptop didn’t get an IP-address reached out. So I checked all on the laptop and my conclusion had to be that it was not cause of this. The problem had to be at the router/network side. The router did came along with the Internet account. So I called the helpdesk of the ISP for suggestions…. a foolish thing to do, I know…
Him: “Goodday, you speak with the helpdesk of <bliep>. How can I help you?”
Me: “Hello, you speak with Rob. I am helping a colleague to set up his laptop for usage with Internet. His other laptop works without any problems, but for some reason this laptop doesn’t get IP-address.”
Him: “I see, Sir. I think the router has lost its connection to the Internet. Could you please reset the router?”
Me: “Ermmm… sure, but I just told that the other laptop is working great over here. But if you want us to reset the router… we will!”
(Of course did resetting the router not help)
Him: ” Strange! Mostly this solves most problems. Then you should turn off the firewall. Firewalls are known to stop many things…”
(Ermm… Firewalls are MEANT to stop things. But most common services are allowed to go through….)
Me: “So you want to turn off the firewall? I mean… sure, the Windows Firewall is not the best one, but still…. Anyway, if you want to have it shutdown…”
(He starts to explain me to click op “start”-button and before he can tell to go to the configuration panel, the Firewall is down…. and of course, this didn’t help at all)
Him: “Do you use any other security software?”
Me: “Of course there is anti-virus software installed. McAfee Virusscan Enterprise 8 in this case…”
Him: “Ahh there we have it. McAfee is crap and it stops the IP requests. Norton does the same. You have to uninstall it… and I will warn you, unstalling might be a problem….”
Me: “You really want me to uninstall the virus-protection???”
Me: “I won’t. And please don’t tell me that anti-virus software stops the network side to supply a IP address…”
(I feel how my blood starts to flow faster… my lips start to tremble… a bad sign)….
Him: “Ohh… hmmm… I see. Maybe I should check the DHCP over here to see if it works well…”
Me: ” Yes…. maybe you check your DHCP…… Do you know what DHCP stands for?” (Dynamic Host Configuration Protocal)
(Some stumbling that show he doesn’t)
Me: “And while you are at it… check you DNS… you know what that means?” (Domain Name Servers…. well, I have to admit that he know that one…. )
(The conversation goes on and slowly I feel myself switch to BOFH mode….)
He: ” We should test if there is any connection to the Internet.”
Me: “Sure. How we do that?”
He: “Do you know how to ping?”
Me: “Funny enough I do. Which IP address?”
Me: “Any? Will 127.0.0.1 do?”
He: “Yes… of course…”
(And he made just a fool of himself… The mentioned IP address is the so called “loopback address”, it refers to the own computer… so if IP is active, a ping to that address will always be successful”.
Me: “Ohhh… it works. And such a fast high response times…”
(Gave him here a change to correct himself….)
He: “Yes, Sir. And as it shows you have a connection to the Internet, so it must be a problem with the laptop itself!”
Sure!!!! I will write tomorrow a mail to the helpdesk manager there….. and I just remembered why I left that bunch 3 years ago….
