As I loaded the tool, I forgot about some of the feedback that I provided on the toolseten-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.technet.com/toml/archive/2009/05/19/r2-capacity-planning-tool-run-through-and-xml-file-problem.aspx#3249446Tue, 02 Jun 2009 21:27:43 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3249446Arnab<p>Hi Tom,</p> <p>I ran into similar problems when using the OCS Stress Tool.The user wont log on and the packet captures revealed incomplete tls handshake.After client and server hello there are no change cipher specs messages exchaged and i see no kerberos authentication happening.</p> <p>I re ran the test with the password xlm change you suggested...but the results are the same as before.</p> <p>Thanks,</p> <p>Arnab</p>http://blogs.technet.com/toml/archive/2009/05/19/r2-capacity-planning-tool-run-through-and-xml-file-problem.aspx#3249448Tue, 02 Jun 2009 21:33:18 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3249448toml-lcskid<p>Getting server logs would help but my first thought would be that the client workstation running the stress is not joined to the domain. If you changed the authentication to NTLM only does it work (restart services)</p>
