Remote App 2012 internal login fail. External work!

Hi,
after working hard to make my externet RemoteApp working (the website was working, but when the application try to start, I was enable to conect to the RD Gateway)

I configure my wildcard certificate (with our external domain) in the deployement->SSL AND in the rd Gateway admin, then configure the NAP server.
Now all external conections work good, authenticated with the RD gateway like expected.

But for an unknown reason internal connection fail. I can connect to the web interface in https, login in the portal, but when I click on a application i got:
"authetication error occurd (Code: 0x8004005)"
I try:
- on my tablet open an application on external network: work good
- on the same tablet open an VPN than open an app: fail with authentication erreur
- I try to go in the RD Gateway and uncheck "bypass RD Gateway for intenal adresse": still falling.

I do not see any error in event viewer.
When I run RD BPA a only got a warning: "The RD Gateway server SSL certificate must be configure with valid certificate subject name". But I already update this SSL certificate with my wildcart certificate

i am lost now! ;-)
thanks

I found the problem.
We do a domain raise functionnality from 2003 to 2008 R2. But for unkown reason, KDC do not work correcltly after that. We need to restart all our DC (maybe only the KDC service will be enough) and then all is working now.
