      And the setting also seems to be enabled in the database:

      | 88 | FOG_CHANGE_HOSTNAME_EARLY | This is an experimental feature that will can be used to change the computers hostname right after imaging the box, without the need for the FOG service. (1 = enabled, 0 = disabled). | 1 | General Settings |

        Is there any way to debug this problem / enable a helpful logfile for this function? I really like your project and would like to use it, but without the early hostname change it is not an option for me.

        I would really appreciate if you could give me some hint where to look out for the problem.

          exactly what do you mean by “not being prepared in any way”
          the very fact that you have a prepared, pre-installed image of a computer that you’re deploying is “preparing” it, unless you’re deploying a factory created default image.

            Well, I mean that I did not perform any special preperation tasks for deployment with fog. I took an image from a system as it is being used, without any special preperation in terms of sysprep, etc. Just booted one of my systems into pxe and pulled the image. When I redeployed it I expected to get the hostname changed, didn’t happen.

              When you say the system is not prepared in anyway, is the uploaded image already joined to the domain? Is the hostname different.

              Your phrasing seems a we bit odd to me. Are these systems registered with FOG? They must be registered in order to change the hostname whether by the FOG Client or after the image. What’s the boot menu look like? Is hostname being sent and being sent properly?

              Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

              Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                Well, I am not sure if there is more to registering a system than what I did. So here are exactly the steps I did.

                1. Set up ubuntu server.
                2. Follow the guide on the website to install fog.
                3. Log in to web interface and add new image file (win7, Multiple Partition Image - Single Disk (Not Resizable) - (2))
                4. Add new Host by Mac address and hostname (inserted the new name i wish to have, lets say NEW1) and added the image
                5. Checked that early hostname change is enabled (unchecked and rechecked to make sure there is no display error)
                6. created upload task, restarted system, uploaded image
                7. created download task, restarted system, downloaded image.
                  result: hostname unchanged, expected NEW1, but still OLD1

                This should be the steps I took if i didn’t miss something. And the computer I’m testing with is not joined to a domain.

                  hostname change early should be working properly under those circumstances. how are you checking the hostname?

                    I just use right click on Computer, Properties. But there I still get the unchanged old name.

                      could you please use regedit to check the values stored in [FONT=monospace][COLOR=#ba2121]HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\ComputerName\ComputerName\ComputerName[/COLOR][/FONT]

                        I will check it tomorrow morning, I am currently not at the place anymore. Thanks already for all the help.

                          I just checked the registry and it still tells me the old hostname. A search for the new hostname inside the registry didn’t find any results, too.

                            We’ve have the same issue over here. None of our stations in Windows 7 is changing to the value registered in the FOG system. They keep the old one.

                              Could it possibly be that i have to change some setting to run the hostname change task like mentioned in this thread? [url]http://fogproject.org/forum/threads/change-windows-hostname-early-just-after-imaging-before-booting.4348/[/url]

                              I don’t think the last partition deployed is the windows partition, so if the default settings didn’t change this could be our problem. Can you tell me where to look at to solve this problem? I wasn’t able to find these settings as I don’t have the folder /bin/fog

                                Okay, I got the problem fixed. The issue really was the script only applying the hostname change to the last partition restored. These are the steps I’ve done:

                                root@e21a101:~# cd /var/www/fog/service/ipxe/
                                root@e21a101:/var/www/fog/service/ipxe#
                                root@e21a101:/var/www/fog/service/ipxe# xz --decompress init.xz
                                root@e21a101:/var/www/fog/service/ipxe# mkdir initmountdir
                                root@e21a101:/var/www/fog/service/ipxe# mount -o loop init initmountdir
                                root@e21a101:/var/www/fog/service/ipxe# vim initmountdir/bin/fog.download

                                Then I added the changeHostname call to line 281 like the following:
                                268 elif [ “$imgType” == “mps” ]; then
                                269 parts=fogpartinfo --list-parts $hd 2>/dev/null;
                                270 diskLength=expr length $hd;
                                271 for part in $parts; do
                                272 partNum=${part:$diskLength};
                                273 echo " * Processing Partition: $part ($partNum)“;
                                274 sleep 2;
                                275 imgpart=”$imagePath/d1p$partNum.img";
                                276 if [ ! -f $imgpart ]; then
                                277 echo " * Partition File Missing: $imgpart";
                                278 else
                                279 writeImageMultiCast $part
                                280 fi
                                281 changeHostname;
                                282 done

                                root@e21a101:/var/www/fog/service/ipxe# umount initmountdir/
                                root@e21a101:/var/www/fog/service/ipxe# rmdir initmountdir
                                root@e21a101:/var/www/fog/service/ipxe# xz -z -9 -C crc32 init

                                That’s it. This way it works perfectly for me. But keep in mind this is a rather quick and dirty fix and only applies to distribution by multicast with a mps type image (Multiple Partition Image - Single Disk (Not Resizable) - (2))! So let’s hope that there will be a clean change to the repos that targets all type of distributions and images.
