I have an older computer that I have retired a year or two ago(I think I wore it out).
I recovered the hard drive from it and installed it into a new computer I have just had built.

A lot of my projects were still on the Hard Drive but a number, for some odd reason, were no longer on it when I hooked it back up.

The computer is listed on the project web sites but not on my hard drive.

So I thought I could just re-attach to the respective projects and all would be restored.

I thought wrong, BOINC keeps generating a New Host ID on each project.

I want to use the old Host ID on each project.

I copied over the account info for each project from another computer which was fine but when each project updated it generated new IDs for each missing project.

From a long while ago I remembered that if I restore the old ID and times it had contacted the servers in "client_state.xml" things would sort themselves out.

This has not worked and generates a new ID again.

So I have changed Host ID (<hostid>) in client_state.xml back to old Host ID
I changed <rpc_seqno> (number of times has contacted the project server) to match account info on project.
I changed <host_total_credit> to match account info.

This has not stopped the generation of new host IDs.

Anyone know what I am missing?

I did this years ago but can't find where I got the information.

Thanks
Conan

Sometimes it just doesn't work right.

Thanks Dr Who Fan

That worked a treat.

I was doing what it said but I was not stopping BOINC to do it so nothing stuck.

I was able to change 11 hosts to match 11 projects in one go. Just one I can't change yet as it has a work unit on it and I can't delete the new host until it gets removed by the server (although I may still be able to reuse my old host even with the new one there, will give it a go).

So I get to keep my old hosts ids (it is the same hard drive just updated hardware), one as low as 36, so didn't want to lose it.

Thanks again

Conan

Great to hear it's working Conan. I keep things like that in my bookmarks and save a text file of the forum notes with original links in my cloud storage for easy access.
