NTLM 2 and Active Directory Update This update adds Active Directory support to Windows 95. The full installation requires Microsoft Internet Explorer 4 to be installed first. If you only need the NTLM 2 support, then instead you may copy the Vnetsup.vxd and vredir.vxd from the "NTLM 2 - Minimum" over the existing ones in your Windows system directory. Finally, to start fully using NTLM 2 you must add the "ntlm2-95.reg" file.
