That's not even a fast machine by today's standards.

1) Do you have the the e-mail of the owner?
2) You can ban the host in BOINC.
3) I believe in BOINC you can set server side rules so that a bad host will automatically get fewer WUs/day until it's down to 1 per day. Then if it starts returning valid results the WUs/day will increase.

>> setting its max_results_day field to -1, let see what happens.

You should be able to do this for all hosts so that this problem will automatically take care of itself. Hosts failing for any reason can be cut off and then build back up if/when the problem is fixed. This is also a service to the owner of the machine as they sometimes won't notice that their host is failing. The work restriction is one way to automatically give them a heads up.

>> The problem here is that I do not have any owner's e-mail address (because of the gridcoin pool mechanism)

Yet another problem with BOINC allowing "pools" of users to register as a single user. There should probably be something like a subteam and require the individual users to provide an e-mail address.

Hello,
There is no available resource on the pool for an individual pool user to locate another pool user by computer id.
