Hi,
When running App\VDI from RD web we have to use the trusted certificate for proper connection. If you are receiving certificate mismatch error then there are certain reason to occur. When publishing RDS externally, you will see a certificate mismatch as the
internal server FQDN’s/IP addresses will show externally during the connection process to RemoteApps or RemoteDesktops.
There are certain solution to resolve this issue.
• Can create a new DNS zone, .COM to allow split-brain DNS (so that internal clients can resolve external names internally)
• Create a relevant DNS entry to point to the RDS environment’s internal IP address
• Create a relevant DNS entry in external DNS to point to the firewall which is publishing RDS’s external IP address
• Use the following script to change the FQDN of the RDP files provided by RD Web Access / RemoteApp and Desktop connection feed
