Citrix users are not able to connect due to certificate issue

RDP configured with a server certificate

Certificate authority no longer available (was on an internal server that was powered off)

ICA users experience connectivity issues

ICA settings are "grayed out"

ICA inherits RDP settings

RDP is set to auto-negotiate; users with issues are auto-negotiating to TLS with an invalid certificate

Fixes:
  • In TSCC.MSC / TSCONFIG.MSC, change RDP to use RDP encryption, do not negotiate. Settings are inherited ICA connections
  • Fix the certificate issue
