Resolve-DnsName returns DNS name contains an invalid character RRS feed

  • Question

  • Gday Guys,

    I have put going on a forum for 5 years now to avoid being a public nuisance. Sorry I finally had to ask stupid questions now. 

    My issue is around doing a simple powershell line. I am not trained and sadly its hard to get my head around.

    If I do Resolve-dnsname -name "http://inranetname/subname/pages/subname%20.aspx", on an intranet site, it complains of an invalid DNS name containing invalid characters. Sadly I cant put in the website names in, as its for a business, but "intranetname" and "subname" are just English lexicon, no special characters there.

    I tried doing quotations, and without, also simply Resolve-dnsname "http://inranetname/subname/pages/subname%20.aspx" but they all say the same thing.

    All i want to do an nslookup but I don't have CMD prompt in our environment and I'm finally taking the plunge into PS.

  • Hi,

    >>I tried doing quotations, and without, also simply Resolve-dnsname "http://inranetname/subname/pages/subname%20.aspx" but they all say the same thing.

    The Resolve-DnsName cmdlet performs a DNS query for the specified name.

    “http: …”, this is not a specified name. This is a URL.

    You can refer this picture:

    To resolve DNS name, you need to enter FQDN or DNS records.

    For example, FQDN:  www.google.com.

    For more details, you can refer the following article:

    FQDN: https://docs.microsoft.com/en-us/windows/win32/dns/naming-conventions

    Name resolution: https://docs.microsoft.com/en-us/windows/win32/dns/name-resolution

    Hope this can help you, if you have anything unclear, please let me know.

    Best Regards,

    Ellen
