48 | NAVISET ADMINISTRATOR 2 USER’S GUIDE
Windows Computer on LAN connections via WMI
When connecting to remote Windows computers via WMI, the following important points must be veried to
ensure a successful connection:
1. The Windows user account used to access the remote computer must have sufcient access
privileges to WMI (specically the ROOT\CIMV2 namespace). Typically Administrator accounts
have sufcient access privileges by default.
2. The password for the account used to access the remote computer must not be a blank password.
3. The Windows Firewall on both the local and remote computers must allow remote access to WMI.
The default Windows Firewall settings typically block access to WMI, thus preventing remote
access to a computer.
The Windows Firewall settings for WMI can also be manually changed from the Windows Control
Panel as shown below, in order to allow remote access:
4. If the Windows computers on the network are part of a Windows Workgroup and not a Domain,
the default UAC (User Account Control) security settings will not allow access to WMI, even if
the Firewall is disabled. Installing the DDC/CI or RS232 WMI Providers on the computer will
automatically congure the security settings to allow access.
