It means that the EVP Office application you’re using couldn’t resolve the hostname of the server it’s trying to connect to, which is usually the result of no Internet connectivity, but might also be caused by a firewall.
At the start of an evaluation, the application will try to connect to dc1.evpsys.com or dc2.evpsys.com (if you’re using the “Classic” evaluation method) or dc.evpsys.com (if you’re using “Secure”). If those names can’t be resolved to IP addresses, then the program will assume you don’t have any Internet access at all.
If you do, however—you might be able to use other applications, like a Web browser—you may instead have a firewall that’s restricted your name resolution. Please contact your IT Department to see if they can explain why the resolution is failing.
Details about how the EVP Office applications connect to our servers is available in the Installation Tutorial.
