Hello, sorry to impatiently post this here as I have already posted it on the Apple forums with no feedback. I'm at cracking point and just looking for alternative ideas to push testing forward.

Basically I'm seeing some strange behaviour with our new macmini, basically we have been using an old Xserve to netboot clients but have just recently setup a new macmini server an enabled the netboot on this. It's already running a few other services such as profile manager and software update and performing great.

I've created some netboot images, transferred some from our old Xserve and also setup some on deploystudio. The problem is, when I boot up a client and go to Sys Prefs > Change startup disk, I can see all the netboot images and if I select a netboot image, the machine reboots, I see the blinking globe and then after a few minutes it boots into the local hard drive.

I've also held down the N key to boot in like I would previously do but similar to above, it boots straight into the local HD. If I old down option, I can see the local HD and the recovery partition but no netboot images (strange? I see them within system preferences!)

Looking at the logs I dont seem to get the BSDP Discover but only this;-

I had our networks guy helped me with using tcpdump to see how the server responds and we only got, he also assures me that the actual server is not sending packets out and suggests its the servers fault? ;-

15:37:13.823326 IP vl316.name1-dist1.net.address.ac.uk.bootps > server.address.ac.uk.bootps:
BOOTP/DHCP, Request from 10:dd:b1:a7:a7:2f (oui Unknown), length 286

(I know the mac address is different as we tried different machines)

I was also advised that we use a helper tool within our VLAN to distribute IP's which was setup on our Xserve and also setup correctly with the new server along with the same ACL's that were copied across.

Ive ran out of ideas on what to test, would appreciate if someone has anymore testing tips or ideas?

Thanks

2p says that your problem is with this. You can test it by netbooting a client on the same VLAN/Subnet as the server, if that works and it doesn't on the other VLAN/Subnet, then you need to pas it back to your network team/person.

You kind sir, were correct!

Looking at the Firewall and ACL stuff now.

Thanks.
