I've got running NW5.1 SP6 + DNSDHCP
Due to some restricions I've got to
assign addresses manualy - and it works fine.

The problem occurs when somebody moves PC to the other subnet
(eg for repairs)
PC won't get any address - neither his own
(that won't be OK due to other address range)
nor first available in this subnet.

I've got to delete in dnsdhcp console manual assignement,
restart console and now it works.

But I cannot be still at work.
How can I manage with this?
