Administration

Usage Notes
To ensure high availability, Horizon 7 allows you to configure one or more replica Connection
Server instances in a Connection Server group. If you disable a Connection Server instance in a
group, the entry for the server persists within the Horizon 7 configuration.
You can also use the vdmadmin command with the -S option to remove a security server from your
Horizon 7 environment. You do not have to use this option if you intend to upgrade or reinstall a
security server without removing it permanently.
To make the removal permanent, perform these tasks:
1 Uninstall the Connection Server instance or security server from the Windows Server computer
by running the Connection Server installer.
2 Remove the Adam Instance VMwareVDMDS program from the Windows Server computer by
running the Add or Remove Programs tool.
3 On another Connection Server instance, use the vdmadmin command to remove the entry for
the uninstalled Connection Server instance or security server from the configuration.
If you want to reinstall Horizon 7 on the removed systems without replicating the Horizon 7
configuration of the original group, restart all the Connection Server hosts in the original group
before performing the reinstallation. This prevents the reinstalled Connection Server instances
from receiving configuration updates from their original group.
Options
The -s option specifies the NetBIOS name of the Connection Server instance or security server to
be removed.
Examples
Remove the entry for the Connection Server instance connsvr3.
vdmadmin -S -r -s connsvr3
Providing Secondary Credentials for Administrators Using
the ‑T Option
You can use the vdmadmin command with the -T option to provide Active Directory secondary
credentials to administrator users.
Syntax
vdmadmin -T [-b authentication_arguments] -domainauth
{-add | -update | -remove | -removeall | -list} -owner domain\user -user domain\user [-password
