The solution was offline during its previous session and will remain offline

If your .Net solution gets disconnected from your Team Foundation Server you might get the following message once you load your solution in Visual Studio. “The solution was offline during its previous session and will remain offline.” in the Output window and your solution is kept offline. Which means your local changes are not picked up automatically and you will need to do manual checkouts and checkins into the repository for local files you have changed.

The trick is to manually reset the values in the registry, where else ?
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\TeamFoundation\Servers\ ( Your TFS server name )

set the values
AutoReconnect = 0
Offline = 0

Next time you open up your solution you will be asked if you want to connect to your Team Foundation Server, yes please.

Update…
If that does not work, try this one
