Hello All,
I am currently experiencing an issue with Migration my DHCP Server from 2003 to 2008 R2. From the 2003 server I exported DHCP server using the "netsh dhcp server export <directory path>". Stopped the DHCP services on the 2003 hosting server. Installed DHCP on the new 2008 R2 server (VM) prior but did not authorize as to avoid any conflicts. Imported the database.dat file, authorized and started the service.
ipconfig /release && ipconfig /renew on the client side and it was unable to find the DHCP server. Let this go for 10 minutes just as to give it time, but no luck.
Using Wireshark on both the server and client system. I performed the following command on the client system ipconfig /release && ipconfig /renew. The client broadcast the discovery packet out to the network, the DHCP server received and send out the Offer packet, but the client does not receive this packet. Stopped services on the server, and restarted on the original 2003 server and client immediate
Troubleshooting:
Reserved IP on the server with MAC Address but still not recognizing the presents of the new server.
Swapped IP address from the old server with the new server, no luck
Migrating a DHCP server role is a very straight-forward task but this is just crazy.
Uninstalled the role, restarted the server, renamed the DHCP folder to DHCP1 (%windir%\system32 directory)
retried and still not luck.
Thinking since this is a virtual machine,lets try it on a physical machine performed the same steps per article:

Still no luck, packet tracing, ensured the ports were open on the server and compared to other
All ports open no firewall again blocking this and antivirus solution has been disabled as well.
Can anyone give me any advise on this issue.
