1) Message boards : Questions and problems : Different hosts getting same ID (Message 75118) Posted 5 Jan 2017 by Timothy Watson Post: A-ha! It was MAC addresses causing the problem. I have PdaNet, the Windows part of an Android app which allows USB tethering so you can use phone as an Internet source, installed on both computers (which I occasionally use on one computer for gaming instead of my awful satellite Internet). The program installs a network adapter, which has the same MAC address on both (all?) computers. It's also the first network adapter which is listed when you do "ipconfig /all". I uninstalled PdaNet from "livingroom", rebooted, went into the client_state XMLs and removed just the field for host_cpid and started BOINC. I checked and a new and different host_cpid was generated, I added the new projects to that computer and a new host is being displayed on the "Your computers" pages of the projects I was having problems with. Thanks a bunch!

2) Message boards : Questions and problems : Different hosts getting same ID (Message 75113) Posted 5 Jan 2017 by Timothy Watson Post: I have two different computers which have the same type of CPU (Intel 3770k), amount of RAM (32GB), and operating system (Windows 7 Ultimate), but they have different hostnames, local IPs, and GPUs. I had been using "bedroom" for a couple weeks on BOINC and then added "livingroom", the problem is that when I did this "livingroom" ended up with the same host ID as "bedroom" on everyone of the projects I was attached to. Between the two clients updating with projects, a lot of work was classified as abandoned. I was using BAM! as an account manager when this happened, and wondering if that was the problem, I removed both computers from the account manager and deleted the client_state.xml and client_state_prev.xml from "livingroom" and restarted BOINC. That computer reinitialized all the projects and received a different host ID. I thought that was the end of the problems until the other day when I decided to sign up for a couple new projects (DENIS@home, pogs, RNA World, and Universe@Home). I did that manually on "bedroom" first and then on "livingroom" and they ended up with the same host IDs on all four projects. I removed "livingroom" from all four projects, that way I can do work on at least one of the computers without the projects thinking I've abandoned the work when the other computer updates with the server and reports not having those workunits, etc. Below are two screenshots of the "Your computers" page from RNA World, one after I've manually updated the project with "bedroom" and then after attaching "livingroom". Identical things happen on DENIS@home, pogs, and Universe@Home (RNA World is the easiest to demonstrate the problem since they don't have any workunits to send out right now). Any help would be really appreciated. I would prefer to not have to delete the client state XMLs again since it would mess up the ongoing work on the computer and if I join another project in the future, what would stop the same problem from happening again?
