NTLM2 is supported since NAS 5.4  But I do not think any NAS 5.5.x code does support Windows 7.  From looking in the support matrix aka elab navigator, support for Vista and W7 started in 5.6.
Hi,   Windows 7 users were unable to connect to the CIFS shares / map them to their desktops. Windows team's packet capturing showed DART is unable to authenticate Windows 7's NTLM2 authentication and requests are declined by the NAS. We have a NS80i with DART 5.5.37.  Does 5.5.37 support NTLM2 at all? Or Can a code upgrade possibly make this work?  Thanks..
Does DART 5.5.37 support NTLM2?
