Home Network folder question mark

Hi,

I have joined my macbook to our Windows domain running Windows 2008 R2 and enable mobile account. Here is my problem:

- When I log in to the network, my home network folder gets mapped without no problems. Everything is good.

- When I log in offline (no domain controller), my home network folder shows with a question mark which is understandable because the domain is not available. If I connect the macbook back to the network while I'm logged in the folder never reconnects. In other words, it shows with the question mark forever. I have to log out and log back in for it to work.

Is there something I can do to reconnect the drive without login in? Many times throughout the day I have to disconnect and connect the laptop back into the network.

Thank you, RG
