Enabling agents to connect from UNIX machines

When an agent connects to a monitored Windows® host from a UNIX® machine, you must make certain registry changes in order to allow the required COM services to run.

To add the following registry key:
1
Click Start > Run.
2
Input regedit in the dialog box and click OK.
3
Add the following registry key to Windows if it does not exist: HKEY_CLASSES_ROOT\AppID{76A64158-CB41-11D1-8B02-00600806D9B6}. Create a new string value named DllSurrogate under that key and leave it blank.
4
Add the following registry key to Windows if it does not exist: HKEY_CLASSES_ROOT\CLSID{76A64158-CB41-11D1-8B02-00600806D9B6}. Create a new string value named AppID under that key and modify the data to: {76A64158-CB41-11D1-8B02-00600806D9B6}
To allow the agent to connect from a UNIX machine to a monitored Windows host:
1
Enable the Remote Registry Service.
Once the agent has successfully connected from a UNIX machine and the Agent Manager connection services have made the required changes, the Remote Registry Service can be disabled.
2
Ensure that the Server service is running.
 
* 
IMPORTANT: Normally the Server service starts automatically. If it is stopped, or fails to start, it must be manually restarted before the Agent Manager can connect from a UNIX machine.

Disabling UAC

Disabling UAC

When an agent connects to a monitored Windows host from a UNIX machine, user access control (UAC) must also be disabled in order for WMI connections to succeed.

This requirement affects: Windows Vista, Windows Server 2008, and Windows 7.

To turn off UAC on Windows 7:
•
Navigate to Control Panel > User Accounts and Family Safety > User Accounts > Change User Account Control Settings, and change the setting to Never Notify.

Granting access to dllhost.exe when Windows Firewall is enabled

Granting access to dllhost.exe when Windows Firewall is enabled

When an agent connects to a monitored Windows host from a UNIX machine, and the Windows firewall is enabled, access to dllhost.exe must be allowed through the firewall.

To grant access to dllhost.exe:
1
Issue the following command on the command-line of the monitored Windows host:
netsh firewall add allowedprogram program=%windir%\system32\dllhost.exe name=Dllhost
2
Ensure that Windows UAC is disabled. See Disabling UAC for details.
3
Restart the monitored host.

Enabling agents to connect locally on Windows

When a WMI agent connects to the same machine it is running on (that is, localhost) using credentials that explicitly specify a user other than the currently logged on user, you must make certain registry changes to allow the required COM services to run.

To allow the agent to connect locally on Windows®:
1
Enable the Remote Registry Service.
Once the agent has successfully connected and the Agent Manager connection services have made the required changes, the Remote Registry Service can be disabled.
2
Ensure that the Server service is running.
 
* 
IMPORTANT: Normally, the Server service starts automatically. If it is stopped, or fails to start, it must be manually restarted before the Agent Manager can connect locally using credentials for a user other than the currently logged on user.
