help.adobe.com’s server DNS address could not be found

Your DNS server is not converting the hostname help.adobe.com into an IP address (for example 23.205.220.88).

You can check this by opening a command prompt, and typing this command:

nslookup help.adobe.com

You should get output similar to this:

> nslookup help.adobe.com
Server:  dns.mydomain.com
Address:  12.34.56.78

Non-authoritative answer:
Name:    a630.b.akamai.net
Addresses:  23.205.220.88
          23.205.220.105
Aliases:  help.adobe.com
          help.wip4.adobe.com
          help.adobe.com.edgesuite.net
          help.adobe.com.edgesuite.net.globalredir.akadns.net

I'd expect you're instead seeing an error, perhaps something like this:

> nslookup help.adobe.com
Server:  dns.mydomain.com
Address:  12.34.56.78

*** dns.mydomain.com can't find help.adobe.com: Non-existent domain

You might also verify that a different DNS server can successfully resolve the address. For example, using Google's server at 8.8.8.8:

> nslookup help.adobe.com 8.8.8.8
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
Name:    a630.b.akamai.net
Addresses:  23.205.220.88
          23.205.220.105
Aliases:  help.adobe.com
          help.wip4.adobe.com
          help.adobe.com.edgesuite.net
          help.adobe.com.edgesuite.net.globalredir.akadns.net

Refer this issue to your sysadmin and/or ISP.

If necessary, change which DNS server you are using. A web search will tell you how to do this.
