Reboot Network Problem

Recently, after each reboot, my Mac wants to connect to the network, but it hangs at the login window. The only solution is to temporarily remove the ethernet cable, mount my external FW drives and then plug ethernet back in and all is good.

This is also happening on one of our other Macs (perhaps after the most recent software update). Normally we don't need to reboot, but occasionally we do, so it's a problem.

Any thoughts?
 
Looks like it isn't finding the network, so it's sitting there until it times out. Can take a while, sometimes.

Err...and how are you mounting external FW drives at the login window?

Probably just removing the ethernet cable, waiting a few seconds, then putting it back in is all you need to do.
 
Do you have a DHCP server set up somewhere, like a router, that would give your mac an IP address? It looks, as Darkshadow said, like your Mac finds a network connection and then tries to get an IP lease from a server that won't give it one for some reason.

Or maybe it's misconfigured (ex. your mac tries to set its own IP but the DSN won't let it).
 
How could the mac be setting it's own IP? I have a problem where when I boot it gets assigned a local IP from my routers DHCP server, but after a shortperiod of time it just assigns itself a different ip, using a different subnet and everything. Until recently it was all fine, then the wireless started playing up, (looks like a dead access point) and now the ethernet port and wirelss both do this strange self assigning of IP's, even though its set to DHCP only.
 
How? System Preferences -> Network -> Ethernet -> Configure IPv4 Using: Manually / DHCP using Manual Address

See the field marked IP: 0.0.0.0 ? ;)
