SLED machines do not show up in DNSDHCP

[fakeferguson]

Hello,

I recently installed a lab of 32 SLED 10 SP2 machines. Aside from what follows, things are going quite well. There have been zero network problems.

I fired up DNSDHCP today to work on something unrelated, but noticed that not a single SLED machine was listed. Not a single leased address on the left side is shown as assigned to any SLED machine. All of my Windows machines are listed by the address assigned.

I went to the lab and got the addresses assigned to several of the SLED machines, and went back to DNSDHCP, but found no entry for any of the addresses that DHCP assigned to those SLED machines.

Is there something that my SLED machines are not doing to correctly register with DHCP? What am I missing?

Thanks,
FF
