When you use Active Directory Service Interfaces (ADSI) to retrieve the Exchange Server 5.5 recipient attribute NT-Security-Descriptor as a binary value, instead of as an ASCII value, you use the binary operator as follows:

set obj = GetObject(AdsPath)
obj.GetInfoEx Array("NT-Security-Descriptor;binary"), 0

If you have not installed Exchange Server 5.5 Service Pack 1 (SP1) or later, you may receive the following error:

Run-time '-2147016694(8007200a)' Automation Error The specified directory service attribute or value does not exist.

If your Exchange Server 5.5 is running on Microsoft Windows 2000 and you choose to modify the GetInfoEx command to not include the binary operator, and then attempt to convert a raw security descriptor to an IADsSecurityDescriptor by using the following code:

obj.GetInfoEx Array("NT-Security-Descriptor"), 0
v = obj.Get("NT-Security-Descriptor")<BR/>
Set propVal = CreateObject("PropertyValue")
propVal.PutObjectProperty ADSTYPE_OCTET_STRING, v
Set sd = propVal.GetObjectProperty(ADSTYPE_NT_SECURITY_DESCRIPTOR)

you may receive the following error:

Run-time '-2147023591(80070519)' Automation Error The revision level is unknown.


To resolve both errors, install Exchange Server 5.5 Service Pack 1 (SP1) or later, and use the binary operator as follows:

obj.GetInfoEx Array("NT-Security-Descriptor;binary"), 0


For a complete sample that demonstrates how to retrieve and modify the NT-Security-Descriptor, see the sample "Setting and Modifying the Exchange Security Descriptor" in the Adsi.htm file. The Adsi.htm file is part of the ADSI 2.5 Resource Kit, which is available for download from the following Web site:

To locate the sample, open Adsi.htm, select Interop, and then click Exchange. You will see the sample listed in the table of contents.
