I was trying to setup with Web Application Proxy Lab on Server 2012 R2 RTM and ran into issue with Workplace Join as it failed to join and encountered error :

Confirm you are using the correct sign-in info, and that your workplace uses this feature. Also the connection to your workplace might not be working right now. Please wait and try again

My Setup was like this :

DC :       Server 2012 R2 RTM
ADFS :   Server 2012 R2 RTM
WAP :    Server 2012 R2 RTM
Client  :  Windows 8.1 RTM

To troubleshoot the issue, I had a look at the Events for Workplace Join in Event Viewer on the Client :

Event Viewer >> Application and Service Logs >> Microsoft >>  Windows >> Workplace Join - Admin

By default they are disabled and on right side of the Event Viewer we need to enable it.

After that tried to join again and then checked Workplace Join Admin events again.

Here we saw Error Event 102 : Workplace Join discovery failed. Exit code 0x80072F19

Connection to EnterpriseRegistration Enrollment website was successful as I was able to access it without any errors.

I had a look at Exit code 0x80072F19 in Err


I enabled CAPI Events in Event Viewer as they are disabled by default

Event Viewer >> Application and Service Logs >> Microsoft >>  Windows >> CAPI2 - Operational

Here I saw CAPI2 Event 81 which talks about Failure for Revocation (80092013)

However I was able to access my CRL successfully from the client machine

To fix this I had to disable CRL Check in Internet Explorer Advanced Settings

Unchecked the option "Check for server certificate revocation " - Don't do it on production setup

Then after that I tried Workplace Join again and it worked fine

I am still investigating the CRL issue as CRL is accessible from client. I will update this Wiki Article as soon as I will get it working with revocation check enabled till then you can play with you LAB without CRL check :)
