Intranet links on BC on-prem ("Link address is not valid")

(0) ShareShare
ReportReport
Posted on by Chris Greenwood 66

Hello

We are having trouble using the links factbox on the item card in BC16 on-prem. If we add a link to a file with an intranet URL, on clicking the link, BC shows the error "Link address is not valid.". (Internet URLs work fine).

I made quick page to test our URLs and found that the ServerFileExists() in the "File Management" CU returns true, and I am able to use the HYPERLINK() function to open the links (although this works only on IE; it seems that Edge blocks intranet hyperlinks).

We have tried both Windows UNC links (\\server\share\file.txt) and file:// links.

Can anyone suggest if there is anything that we might need to configure to get around this error?

Thank you.

Chris

    Hi Marco. We were under the misapprehension that "intranet URLs" would also include UNC paths. Thank you for the clarification.

    Hello,

    Docs how to to this can be found here:

    docs.microsoft.com/.../ui-how-add-link-to-record

    In bullet point 4, it says:

    The link must be a valid internet or intranet URL.

    Unfortunately in the Webclient we had to block linking to local files as the browser security model would not allow that anyway. It must be a valid internet or intranet URL.

    The message is just reality these days. So bad people inventing vulnerabilities are bad. Browsers would block this behavior and partners have to move towards the cloud anyway.

    A nice solution for this problem is to have internet/intranet links instead for instance to a OneNote hosting all possible document content.

    The link would be safe (http or https) and the files would be hosted securely. This is what is means with "The link must be a valid internet or intranet URL". In browser, linking to a local file is not possible.

    The behavior is by design.

    Thanks.
