I have several machines running BOINC for Seti@home and over the course of the past few months as I ramp up CUDA systems I seem to be getting 'Scheduler request failed: Error 403' messages about once a month. When it happens it seems the only way to correct the issue has been to disconnect/uninstall and reinstall/reconnect. It bit me again today as I saw my MLIDVWINTA02 system getting the message after finishing up over 500 tasks and trying to report them. The tasks I did still see in my task window all finished within a minute which was very strange too. Since the system is in the office, running Server 2008 under a domain account, I cannot reset it remotely. (When using Remote Desktop and doing any restart of BOINC, BOINC never sees the CUDA processor since Remote Desktop goes in using a pseudo graphic system, so I always have to be in front of the system to do an install.)

Anyone else been plagued with the 403 (HTTP code meaning 'forbidden') message?

I assume it goes through a proxy? if so, try setting that system up with HTTP 1.0

For this, make a cc_config.xml file in the BOINC Data directory.
Add into it these lines:

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

Save the file, make sure the extension is .xml, not something else (like Notepad likes to make it .txt).

Then either restart BOINC, or open BOINC Manager->Advanced view->Advanced->Read config file.

I added the cc_config file, but a read of it did not fix the issue. I wound up resetting the project, and I am back up for now.

---

Turns out that cc_config on my 'proxied' machine prevented all internet access. Had to disable that config.

Since I'll like to test the new x86_64 test application for windows I've attached a 64 bit server and see the same problem:

11/2/2009 5:38:20 PM|boincsimap|Sending scheduler request: Requested by user. Requesting 2033120 seconds of work, reporting 0 completed tasks
11/2/2009 5:38:25 PM|boincsimap|Scheduler request failed: Error 403

but only on the win2003 server x86_64, all the other 32bit PCs works fine with the same proxy configuration (that already include the cc_config.xml file with the <http_1_0>1</http_1_0> param).

Any ideas ?

You don't say which BOINC version you're testing with.

Ops, wrong forum, the problem was about SIMAP ... my mistake sorry :)
