<div class="content wysiwyg-content">
In the step: Configure Pool / DNS, &nbsp;i try to configure OCS to allow for automatic client logons. <br />
However i get this error: &nbsp;<br />
Unable to retrieve the instance of WMI class 'MSFT_SIPPoolExtData'. Ensure the WMI service is running, check network connectivity and make sure you have enough privileges.<br />
(Error code: 0x800407D0)<br />
<br />
I log in as domain administrator, it is in local admin group and system admin in sql server instance.<br />
I get the login failed error in event log from sql but the user should already have enough permission.<br />
i install sql and OCS in a x64 windows 2003 server, is the issue related to x64 server?
