To display a list of server instances, run the list-instances subcommand of the asadmin utility command with the --long option specified.

```
- cluster_name is displayed only for cluster configurations that contain multiple Java EE servers.
To display a list of web servers, run the list-webservers subcommand of the asadmin utility command.
```

```
When this command is run, the result is displayed as follows. Ensure that the statuses of the web servers are not running.

If necessary, back up the environment information by running the backup-domain subcommand of the asadmin utility.

Verify the output backup files.
Back up the files (the server templates for example) that are managed in locations other than the domain directory.
If the distributed COM is enabled, disable DCOM on the remote host and the local host.
1. In Run in the Start menu, enter dcomcnfg.exe, and then click OK.
2. In the Component Services window, click Component Services > Computers to expand the tree.
3. Right-click My Computers, and then select Properties.
4. On the Default Properties tab of the My Computer Properties window, clear the option Enable Distributed COM on this computer.
5. Click OK to restart the computer. Note that if DCOM is already disabled, you do not need to restart the computer.
6. If the machine is restarted and thus the domain administration server is started, run the stop-domain subcommand of the asadmin utility command to stop the domain.
To disable the DCOM settings, run the setup-local-dcom subcommand of the asadmin utility command in the remote host.
```
asadmin setup-local-dcom --unsetup
```
Important note

When updating the Windows registry information, we recommend that you first back up the registry information before executing the setup-local-dcom subcommand.
When this command is run, the result is displayed as follows:
```
Command setup-local-dcom executed successfully.
```
For Windows 8, Windows 8.1, Windows Server 2012, or Windows Server 2012 R2, restart the Windows service Remote Registry on the remote host.
