The Negotiate provider should fall back to NTLM however if Kerberos authentication fails, which seems to happen in your log. NTLM also fails, possibly because no password was given. Perhaps passing it to mpiexec would work (/pwd)? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
