Cause

Security settings are interfering with Java.

Resolution

On the Win7 and Win2k8 boxes do the following:

1.  Run gpedit.msc
2.  Under Local Computer Policy expand "Windows Settings > Security Settings > Local Policies"
3.  Click on "Security Options"
4.  Scroll down and right click on "Network Security: LAN Manager authentication level"
5.  Change the level to "Send LM & NTLM- use NTLMv2 session security if negotiated".
6.  Apply and OK the changed settings.
 

 On the server set, or leave, this setting to "Send NTLMV2 response only. Refuse LM"".
