D365 on-prem Org with Windows Authentications issues when trying to surf to it on the hosting web server

(0) ShareShare

Posted on by 702

The setup -

So we have a dev D365 on prem environment which contains a Web server and a Full server.

Currently the Claim-based Authentication and IFD are both disabled.

DNS record "xxx-dev.crm.company.com" is created and pointing to our Net Scaler which then in turn pointing to the web server's IP address.

The Issue -

Whiles I can browser to the relevant org from all other desktops as well as from the Full server;

but when I am on the web server I can't surf to the org or any other org created in the same environment, as windows security just keeps prompt me for user name and password.

However if I replace the web address  "xxx-dev.crm.company.com" with localhost or the IP address of the web server box or the web server box name, it loads the org as expected.

The Question -

what have I missed? or any ideas on how to trouble shoot this please?

Many thanks in adv

    Hello Xun Dong,

    This is normally due to either internet options lacking placing sites on the trusted sites, or the loopbackcheck is blocking that access.

    docs.microsoft.com/.../accessing-server-locally-with-fqdn-cname-alias-denied.

    I would give it a go on creating the registry key to disable loopbackcheck, just to confirm the behavior.

    Keep us updated!
