I have a virtual Windows Server 2008 created by VMWare that is taking up multiple IP addresses on my DHCP. The DHCP server is on my Sonicwall 2400 appliance. The server already has a static IP address assigned. So this is what I am getting. I come in every morning and any remaining IP addresses are leased by the same MAC addresses which blocks others from obtaining an address. I can delete the leases and it will take the remainder of the day for the server to reach out and grab the unassigned IP addresses. I have my tech company working on this but so far no luck. Has anyone out there had this issue and what was the solution?
