Is there any way to exclude/remove an "Untrusted Domain" (which I have linked via a domain bind user) from the domain list of the Horizon (web) cliënt?

Using vdmadmin doesn't work, because it's not an 'active' domain. (vdmadmin.exe -N -domains -exclude -domain <domain netbios> -add)

In addition, not being able to change the alphabetical order is also quite annoying.
