The simplest thing would be for the Windows sysadmin to just delete the lease and let it be reassigned. It ought not be but a minute to do. (I am not in front of one of my Windows servers, so I can't tell you exactly what steps to do.)
Alternatively, you could force your system to have
the same IP that it had when it was called "linux."
Well, isn't the main point he is looking for is not so much what the IP
is, but the name assigned to that IP address?
When DHCP issues an IP to a system, it also registers the host name in DNS and possibly
WINS (depending on configuration, I guess). (I'm more familiar with the details of Samba
then Windows itself.)
I'm too lazy to wade through the RFC on this, but is name assignment a
part of the DHCP protocol, or part of Microsoft's "Embrace, Extend,
Extinguish" approach?
I browsed the RFC, which doesn't seem to mention host names in it.
From reading the RFC, releasing a lease is supposed to terminate the lease term. In my experience,
Windows, at least, continues to reissue the same IP to the same MAC, even after a DHCP release.
I'm puzzled over why the DHCP server would be issuing "linux-1". That doesn't sound like
right behavior. Typically the CLIENT sends its host name, which is what gets registered by
the DHCP server into DNS. I know you can do the reverse, but I thought you had to manually
assign the host name based on MAC. So, it would be the Windows sysadmin's responsibility
to manually assign the name "linux-1" (or re-assign the name "linux").
In any event, spoofing the MAC address of the previous NIC would be the most seamless solution.
Or having the Windows sysadmin delete the lease.
