Vista NTLM Setting

A few users have reportedly had troubles with accessing storage devices that require NTLM authentication. For those running vista, you may or may not know that it only uses NTLMv2 authentication and therefore it won’t work.

To get your storage device to work with Vista, you can enable your Windows Vista PC to use both NTLM and NTLMv2 authentcation, in order to communicate with older SAN devices.

Solution

  1. Click the Start Menu, then “Run”
  2. Type “secpol.msc”
  3. Select Local Policies
  4. Select Security Options
  5. Find Network Security: LAN Manager
  6. From the drop down list, select: “Send LM & NTLM – use NTLMv2 session security if negotiated”

Now you should be able to communiate with older SAN devices in Windows Vista!
