    Billy it's a matter of perception and personal experience. Most of us (100% me) we are interested but not dealing with large scale customers/software solutions/ITS often. It's just another level with guys like rthonpm and others I know.
    I'm really struggling sometimes to understand those engineers but have to live with that

    You're right that it is a matter of perception. Most of my clients aren't running a server and the OP didn't mention it, so I assumed they weren't running active directory. But he's right and has a valid point. I should have asked and not assumed. I'm cool with that...it keeps me on my toes.

    Had it in both scenarios to be honest had one with a large network all connected with many servers probably and a small company in an office with a dozen pcs.

    What causes it to not work? What was really strange with the small network is NSLOOKUP on a pc worked fine but at the copier with the same DNS it wouldn't connect. The larger network I guess was probably some crazy firewall issue as it was a public sector customer.

    How do you guys explain it to your customers when you get this sort of problem?

    The purpose of NSLOOKUP in this case is to see if the IP address is being resolved to the hostname of the device or website. So, if I type in: NSLOOKUP gmail.com and it returns both the IP address and hostname, you should have no problem with DNS.


    If it works sometimes but not others, I'd try changing the external DNS and replacing it with something else. What external DNS server are you using?
