While standards are important,
WBEM and JMAPI are still in the evolutionary stages (they are drafts, not standards).
Nevertheless the list of what's not available under WISE is extensive and these are just some of the most important: Active Directory, ActiveX Data Objects, COM/DCOM, COM+, OLE, COMGDI (post NT 4.0), Printing (post NT 4.0), ODBC, OLE DB, DirectX, Security (NTLM, Kerberos, Public Key Infrastructure, Directory Services and Distributed Security), Multimedia (post NT 4.0), Active Server Pages (ASP), NetDDE Remote Access Service (RAS), Telephony API, Windows Networking License Service API, and
WBEM.
