After I installed VBox I noticed that it takes a long time for my network connection on my laptop to connect to a network. It doesn't matter if it is a wireless or wired network, and doesn't matter if it is the same network it was connected to before being shutdown. It takes on average around 3-5 minutes to finally connect to a network. If I try to run ipconfig /renew I get messages that all my devices are not connected to a network and the DHCP operation fails. I just upgraded to the latest version and it did the same thing when updating the network drivers, so I am 99% sure it is something in the VBox drivers, not something unique to my laptop's OS. Before VBox I could bring my laptop out of sleep and it would be connected before I could get logged in.
Some info on my laptop. Dell Precision M6500 running Win2k8 R2 running as a domain controller, DNS, DHCP and various other services (all my VM's use the host for AD services). I have all my network adapters set to use localhost as a DNS server and the DNS server set to forward unknown requests to Google's public DNS.
Anyone have any idea what might be causing this?
