My main machine suffered some sort of failure today and a hard boot was required. When it restarted Boinc seemed to start from scratch creating a new account on all my projects and downloading new work from projects that were suspended. I should have 374 tasks in progress but the "new account" created has 2. How can I combine the two accounts and get back my 374 tasks

The machines in question are:

4489474 original

6648533 newly created "double.

Here how to revert back to your old id:

How to revert to an older HostID number?

You've nurtured your low hostID number for a couple of years and all of a sudden BOINC decides it's time you got a newer one. Is it possible to revert to the older number? Well yes, here's how.

1. Make sure you have no tasks in your queue (Finish & Upload, abort, report them all)
2. Go to the web site of the project, your list of computers and find your old Host ID number.
3. Stop and Close BOINC.
4. Edit client_state.xml, find the <hostid> tags and replace the number here with the old ID.
5. Find the <rpc_seqno> tag and increment the number here with one or two.
6. Save client_state.xml
7. Restart BOINC.

Now whatever you do, do not merge the hostIDs on the web site, or else you'll be stuck with the higher ID number. Just wait for all the tasks in the new ID's number to time out, then delete the ID when it has no tasks listed anymore.

Edit: See Richard's response in the 'Apologies to wingmen: Hard Drive Failure all work lost' thread for more clarity.

Well I I thought I followed your instructions to the letter, but all I have done is succeed in creating 2 more computers!!!!

I wasn't sure first time what is meant here;

5. Find the <rpc_seqno> tag and increment the number here with one or two.

The number was 3 so I made it 4 was that correct?

You need to make the <rpc_seqno> a couple of number's higher than what is on the website for that host's "Number of times client has contacted server" value, from the host details page its 31674 contacts, so make the <rpc_seqno> 31676
