Hello gyu,

Looking at your description and powerpoint, it appears as if your configuration on the zenon side is correct. Or at least, I do not see any obvious errors. This error message leads me to believe there is still a network related issue concerning name resolution.

Perhaps as a test, you can verify that you can successfully ping in the following situations:

- From the Web Client can you PING the Web Server via HOSTNAME?
- From the Web Server, can you PING the runtime server via HOSTNAME?

Can you successfully launch another web client from the INTERNAL network? If so, it may be worth investigating the Cisco firewall configuration. Additionally, if the web client successfully starts on web server machine, then I think that significantly narrows your problem down to network related issues (firewall, DNS, etc.).

Here are some additional topics that may be worth checking:

Is the name resolution in the network working correctly?
From the remote web Client computer can you ping the Server by hostname?
From a remote web Client computer can you ping the Server by IP address?
(a ping by must always return the identical name (Case sensitive!) on all PCs, use the option ping -4 to force IPv4)

Try to delete the %TEMP% directory on the web Client computer.

Try to add the URL of the zenon web Server to the “Trusted Sites” of Internet Explorer.

In Internet Explorer 10, try to turn on “Compatibility Mode” in the Tools menu.

Disable/uncheck memory protection in the browser (Tools -> Internet Options -> Advanced -> Enable memory protection to help mitigate online attacks).

If you still are unable to find the error, it would be highly suggested to contact your local Copa-Data support representative at that point.

Regarding a Enable DEP,

Should i uncheck a Enable DEP on the web server PC ??

DEP needs to be deactivated on the PC where the WebClient is running when using the browser Internet Explorer (and only if VBA is used in the project)
