Working with Office Communications Server User Instances

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

These code samples illustrate how to connect to the Windows Management Instrumentation (WMI) service and how to create, update, and delete user instances.

All of these code samples require Office Communications Server to be running and available on the user's home server. If the user is homed on another Office Communications Server in the domain, WMI must still contact that particular server.

To execute these code samples, you must be a member of the Office Communications Server Domain User Admin group.

This function connects to a remote computer and creates a new Office Communications Server User instance on it.

Public Function CreateInstance(InstanceId, Enabled, PrimaryURI, UserDn, HomeServerDN)

Set DefaultSIPUserInstance = GetObject("WinMgmts:MSFT_SIPESUserSetting")

'Do error checking here.

Set NewSIPUserInstance = DefaultSIPUserInstance.SpawnInstance_

NewSIPUserInstance.InstanceID = InstanceID
NewSIPUserInstance.UserDN = UserDN
NewSIPUserInstance.HomeServerDN = HomeServerDN
NewSIPUserInstance.PrimaryURI = PrimaryURI
NewSIPUserInstance.Enabled = Enabled

Err.Clear()
NewSIPUserInstance.Put_ 0

'Do error checking here.

CreateInstance = true

End Function

This function connects to the WMI service and updates an Office Communications Server User instance with the specified values.

Public Function UpdateInstance(InstanceId, Enabled, PrimaryURI, UserDN, HomeServerDN)

' Connect to the WMI server.
Set wmiServer = CreateObject("WbemScripting.SWbemLocator").ConnectServer()

Query = "SELECT * FROM MSFT_SIPESUserSetting where InstanceID = '" & InstanceID & "'"

Set LCUserEnum = wmiServer.ExecQuery(Query)

For each LCUser in LCUserEnum

'//update values here
LCUser.InstanceID = InstanceID
LCUser.UserDN = UserDN
LCUser.HomeServerDN = HomeServerDN
LCUser.PrimaryURI = PrimaryURI
LCUser.Enabled = Enabled

LCUser.Put_ 0'0 for create or update

'Do error checking here.

Next

UpdateInstance = True

End Function

This function connects to the WMI service and deletes the specified Office Communications Server User instance based on the supplied primary URI of the user.

Public Function DeleteInstance(UserURI)


' Connect to WMI server

Set wmiServer = CreateObject("WbemScripting.SWbemLocator").ConnectServer()

'Do error checking here

Query = "SELECT * FROM MSFT_SIPESUserSetting where PrimaryURI = '" & UserURI & "'"

Set LCUserEnum = wmiServer.ExecQuery(Query)

For each LCUser in LCUserEnum
Err.Clear
LCUser.Delete_

'Do error checking here
Next

DeleteInstance = true

End Function
