Virtual AES Ver: mvap-sms-3.1.704.14-1

virtual AES

Hi Bill,

I believe I know why you are seeing the 'Connection Failed' error messages on your real AES server. Microsoft .Net has a preauthenticate property that you can set in the SOAP request which is "supposed" to send the user credentials on the initial HTTP post. I am not sure why, but after running some packet traces this does not seem to be happening when you set preuthenticate=true. SMS has addressed this issue in AES 3.1.2 and greater, which is why your virtual environment succeeds! I would suggest upgrading to AES release 3.1.2 or greater if possible. If you must remain on this load of AES you will need to manually set the Authentication Credentials in the HTTP header so that the initial SOAP request contains the Authentication Credentials. Sorry for any inconvenience, please let me know if you have anymore questions.

Thanks,
