        so it is proceesing the requests ok - try adding a simple task like mem test or inventory - should all work ok but to get it to boot local have a look at this [url]http://www.fogproject.org/wiki/index.php/Boot_looping_and_Chainloading[/url] - can you post the default file /tftpboot/pxelinux.cfg/default

                On the subnet where I have my Fog server setup, it PXE boots just fine. On any other subnet, it will not get a DHCP address which leads it to be unable to PXE boot.

                  so if that subnet isn’t getting dhcp - is there a scope set on the windows box for that subnet with a pool set - is the pool exhausted ? check to see if the pool isn’t exhausted …

                    right ?[B][/B]

                      also check to make sure you are able to route to your fog server …

                          The pool is definitely not exhausted. If it boots to Windows, it gets its DHCP address.

                          Yes (to your second post).

                          In my internal network, there is no firewall whatsoever.

                                On a Windows box in the 10.110.100.x subnet, the OS pulls this from my DHCP server:

                                DHCP Enabled: Yes
                                Autoconfiguration Enabled: Yes
                                IPv4 Address: 10.110.100.92
                                Subnet Mask: 255.255.254.0
                                Default Gateway: 10.110.100.254
                                DHCP Server: 10.200.200.3

                                However, if I PXE boot, it never gets DHCP so it doesn’t continue into PXE.

                                I use to use Alitirs and it worked just fine. We had its PXE server set to “Use the DHCP port.”

                                  Here’s something else that is interesting:

                                  When I’m booting a PC on the same subnet as my Fog server (10.200.200.203) and I choose to get IP information once I’m inside Fog, it shows that DHCP gave out the correct address.

                                  It has to be something to do with my other PCs being outside of that subnet. We divide each lab into a different subnet so there’s no way that I can really join them all together.

                                    Alright, somehow, I made progress today. I can now successfully PXE boot in two out of eight labs.

                                    I’ve been attempting to upload an image and when it gets to mounting the NFS share, I get the error: Bad descriptor file and then it restarts. Once again, I’m lost.

                                      I reinstalled Fog and put my DHCP server as the router’s address. This got me past the bad descriptor file error.

                                      Now, I get: “RPC remote system error connection refused.”

                                      Who knows if I’ll ever get this working. It’s just one error after another.

                                          hey guys…

                                          could possibly be unrelated… but…
                                          we were having issues with TFTP Timeout when it came to subnets other than the one fog was on… it turns out the switch needed configuration to allow spanning subnets (not sure on exact terminology but 5 minutes after the network guy worked on the core switch, it was working).

                                          the bad descriptor problem, I resolved by making sure that .mntcheck was in both the /images and in the /images/dev folder…

                                          good luck… let us know how you go…

                                            I think it’s something along the lines of ip-helper on the managed switches.

                                            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.
