The new download pages on TechNet have just about any link you need for OCS 2007 R1/R2. My only criticism is there should be a section for all the latest hotfix patches. The Updates Resource Center has all the latest hotfix patches and firmware. Thanks Adam!

So you’re in the middle of an OCS deployment and you need to change a WMI value. It’s easy to use PowerShell to view and modify OCS 2007 R2 WMI values and I find it to be much easier and faster than using the alternatives, WBEMTest or VBScript.
The PowerShell command that makes this possible is Get-WmiObject.
To view WMI values, use the following syntax:
PS > Get-WmiObject -computer HOSTNAME -query "select * from WMI_CLASS where
backend='SQL_SERVER\\SQL_INSTANCE'"
Enterprise Edition Example:
PS > Get-WmiObject -computer ocsent_hostname -query "select * from
MSFT_SIPGroupExpansionSetting where backend='SQL01\\OCSInstance'"
Standard Edition Example:
PS > Get-WmiObject -computer ocsstd_hostname -query "select * from
MSFT_SIPGroupExpansionSetting where backend='(local)\\rtc'"
Depending on where the WMI value lives, you may not need the
where backend='SQL_SERVER\\SQL_INSTANCE'
For example, the where clause is not necessary when using WMI to query Mediation server config settings. This is because a Mediation server is not associated with a particular pool. Any value that is associated with a particular Enterprise Pool or Standard Server will need this where clause.
Mediation Server Example:
PS > Get-WmiObject -computer ocsmed1 -query "select * from MSFT_SIPMediationServerConfigSetting"
This should produce output that looks like this:
__GENUS : 2
__CLASS : MSFT_SIPMediationServerConfigSetting
__SUPERCLASS :
__DYNASTY : MSFT_SIPMediationServerConfigSetting
__RELPATH : MSFT_SIPMediationServerConfigSetting.InstanceID="{...
__PROPERTY_COUNT : 17

So now we can view WMI values in PowerShell, let’s see how to change a WMI value. I’ll show you how to configure the Mediation server to strip the leading (+) plus sign from outbound calls. For this example, the Mediation server is named ‘ocsmed1′.
First, I want to store the Mediation server WMI values in a temporary variable.
PS > $temp = Get-WmiObject -computer ocsmed1 -query "select * from MSFT_SIPMediationServerConfigSetting"
You can verify that the values were stored correctly by typing the variable and hitting Enter. It should return the exact same output as shown above:
PS > $temp
Now set the ‘RemovePlusFromRequestURI’ value to true:
PS > $temp.RemovePlusFromRequestURI = $true
Next, write the changed values back to WMI:
PS > $temp.Put()
On Windows 2008, use the following command to install PowerShell:
Servermanagercmd.exe -install powershell
