I did a google search and found HTTP Error 417 - Expectation failed.

You could try switching from htt protocol version 1.1 to version 1.0.

To do so, you must create a text file named cc_config.xml in your BOINC data directory (if it doesn't exist already). The data directory is mentioned in the message tab of BOINC manager.
With a texteditor, enter (copy&paste) the following into that file:

<cc_config>
<options>
<http_1_0>1</http_1_0>
</options>
</cc_config>

There are no lower case 'L' characters in that code, only digits '1'. More information to cc_config you can find here.
In BOINC Manager (Advanced view) select menu 'Advanced->Read config file' to activate the new configuration.
Hope that helps.

Gruß,
Gundolf

I was getting the same error on CPDN when their BOINC server was intermittently unreachable, a few days ago. It went away when the CPDN BOINC server returned to normal operation.

where is the config file on win2000

Look at your Messages tab. After a restart of the BOINC client it shows something like this:

18/04/2009 10:48:29||Starting BOINC client version 5.10.45 for windows_intelx86
