Hi

I installed BOINC 6.2.18 two days ago. It worked fine in the first 2 days.

But today after I boot the computer, I found that the BOINC service failed to start automatically, I tried to start it manually, but got error message as follows:

could not start the BOINC service on local computer Error 5: Access is denied

I tried several times and got the same error messages.

I'm run XP Pro, I did a disk check before the booting today, does this matter?

Cheers

That depends. Did it fix anything that you know of?
What does it say in Event Viewer (Start->Control Panel->Administrative Tools->Event Viewer)?

Usually you get an Error 5: Access is Denied when you're trying to connect to a remote computer without a password or you do not have permission to log on to a remote computer. Is this BOINC on the local computer or a remote computer?

I don't what happened when it did disk check, I didn't watch it.

It's a local computer and I'm using adminstration account,
Here is the error message from event log

Sounds like you or something else changed the password on the BOINC service. Did you try to change the password on the BOINC service?

I think your best bet is to uninstall BOINC and reinstall it. That should fix the password problem and allow the service to start again at logon.

I didn't touch the password.

I reinstalled it, and now it works fine.

What's the password on the BOINC service? Can I change by myself?

From the FAQ:

Passwords
Q. Can I change the password on the boinc_master and boinc_project accounts?
A. Yes you can.
You will need to need to go to the service control manager and update the password to start the service (boinc_master). (BOINC->Properties->Logon)
Next you need to use a base64 encoder to rehash the password (*) and fill this in in the client_auth.xml file in your BOINC data directory. You can use a base64 encoder online, such as this one.

Do know that the passwords on the accounts are set to never expire.

(*) I did find elsewhere that it's a rehash of the password and username, but I will have to ask about that. The above I got directly from the developer.

That's what Ageless meant for you to look up ;-)

There's the output of chkdsk too!

Another interesting finding.

When I uninstalled BOINC, it didn't delete boinc_master folder under C:\Documents and Settings, after reinstalled it, it built a new folder called
boinc_master.[my computer name]
