Strange DHCP Issue

Hello - We seem to be having problems with our DHCP servers. I'll post an
example below but let me attempt to describe firstly.

When setting up new workstations on the network (TCP) they occasionaly take
upto 30mins to pick up an address. We started to investigate this so I
decided to ping the workstation by name, resolved its IP fine so i took a
note of it. Out of interest i tried pinging the same workstation by that IP
with the hostname resolve switch added ( -a). To my horror, it showed 2
completely different workstations !

Here is a copy/paste from my CMD window.

Any help with this would be much appreciated - where should i start looking,
what should i be looking for etc.

mhh, i see no problem, such constellations can be done.
This is ethernet

Where is the problem?

If there any with your DHCP Server, you maybe post what type of
Server you using.
