Verify Administrator Credentials
Only a credential that has administrator rights on the target server has the necessary permissions to
access the target host’s WMI services. Make sure that the username and password you are using
belongs to an administrator on the target host.
If the administrator credential is a domain member, be sure to specify both the user name and the
domain in standard Microsoft syntax. For example:
DOMAIN\Administrator .
Enable Remote Procedure Call (RPC)
Remote WMI connections use RPC as a communications interface. If the RPC service is disabled
on the target server, remote WMI connections cannot be established.
These steps show how to enable the RPC service:
1 Log on to the target host as an administrator.
2 Click Start > Run , then type services.msc , and then press [Enter].
3 Right-click Remote Procedure Call (RPC), and then click Start on the shortcut menu.
Configure Distributed Component Object Model (DCOM) and User
Account Control (UAC)
If the target computer is running Windows Vista or Windows Server 2008, you may be required to
make settings changes to allow remote WMI requests (See
msdn.microsoft.com/enus/library/
aa822854(VS.85).aspx
).
DCOM —Edit Default and Limits permissions to allow the following actions:
• Local launch (default permission)
• Remote launch (default permission)
• Local activation (limits permission)
• Remote activation (limits permission)
For more information, see
Enabling DCOM on page 719.
