The request failed with HTTP status 417: Expectation Failed.
If you see this error when calling a web service probably you need to add the following section to the configuration file of the caller application:
<servicePointManager expect100Continue="false" />
like here:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<system.net>
<settings>
<servicePointManager expect100Continue="false" />
</settings>
</system.net>
</configuration>

This can be the issue when trying to use Playbooks.exe of the Project Server 2007 Resource Kit. If you get the Please set URL, Username, password correctly error when trying to log in, just check the playbookslog.txt file next to Playbooks.exe. You may find a similar error that can be resolved with adding this setting to the Playbooks.exe.config file.

I have the same problem, and tride to add the above code to “dexplore.exe.config” in path
“C:\Program Files (x86)\Common Files\microsoft shared\Help 8, ”
and restarted IIS, but my problem did not solve.
Also tried to add the same code to “web.config” on my applications but
got another error
“The request failed with an empty response.”
