Error Messages When Router (Activeds.dll) Calls OpenProcessToken() with TOKEN_ALL

SYMPTOMS

Code that is written to use the ADSI ADODB provider and to set Integrated Security to "SSPI" may not work and may generate "Access denied" error messages when the code tries to use the Open and Execute methods of the ADODB.Connection object.

This problem may occur when you use Active Directory Client Extension for Microsoft Windows NT 4.0 Workstation to query against Microsoft Exchange 5.5 Server by using ADSI. The error codes that you receive when this problem occurs may include any of the following messages:

Access denied

0xc0000022

E_FAIL

0x80004005

CAUSE

If you use the ADSI ADODB provider (ADsDSOObject) with the Integrated Security property set to "SSPI," the OpenThreadToken and OpenProcessToken functions are used, and TOKEN_ALL_ACCESS is supplied for the DesiredAccess parameter.

Microsoft Knowledge Base article Q225091 indicates that TOKEN_ADJUST_SESSIONID is a new access mask for Microsoft Windows 2000 and Microsoft Windows XP. Because Windows NT 4.0 does not define TOKEN_ADJUST_SESSIONID, calls to OpenThreadToken and OpenProcessToken in Windows NT 4.0 with this flag may cause error messages.
