Win 7 Pro x64 slow to set up network connection

#1
I have Windows 7 64-bit connecting to a hybrid Windows/samba network.

On boot, Win7 takes 1 - 2 minutes to negotiate a DHCP lease; set to a static, it takes about the same amount of time to connect. Other Vista and XP PCs connect in seconds. I have tried:

  • Replacing the switch
  • Enabling Spanning Tree Protocol and Fastport on the switch
  • Replacing the DHCP server/gateway
  • Updating the Win7 NIC drivers
  • Selectively disabling components in startup (removing the Nero components helped a bit)
  • Disabling IPv6 and Link Layer Topology drivers in Local Area Connection properties
  • Changing from one firewall (Forticlient) to another (COMODO) - both 64-bit
I've searched high and low for other solutions, but no success. Any advice would be appreciated.
