VirtualBox – Bridged Adapter in VirtualBox Cannot Obtain IP

I have virtual box with RHEL installed. My virtual box is running on windows 7 64 -bit. I configured bridged connection, but when I am restarting network interfaces, I receive following error:

Determining IP information for eth1... failed

On Windows XP it works without problems. I disabled Windows Firewall and installed latest Virtual Box, still without success.

NAT is working without any problems. What did I missed?

UPDATE

Ouput of ifconfig -a is:

Moreover the same machine with the same configuration works well on Windows XP. The problem is only on Windows 7.
