Symptom
Following the interruption of the connection:
- A spinning cursor may appear.
- New applications may not open.
- The Finder becomes unresponsive.
For example, this occurs when connected to a shared volume and the:
- IP address or Network Location of the computer is changed, or
- Computer is put sleep and then wakes when or where the server is unavailable, or
- The server is shut down, or the server's IP address is changed.
Note: Changing the Network Location may refer to two different actions. First, it may refer to using the Location menu to switch between locations in the Network preference pane. Second, it may refer to putting a portable computer to sleep while still connected to the server, carrying it to a different physical location, and then waking the computer where the server cannot be reached. An example of the latter would be connecting an iBook to a server at work, putting the iBook to sleep without first disconnecting it from the server, then waking the iBook at home.
Solution
To resolve the issue, you may have to force restart your computer using the power or interrupt button.
Avoid the issue in the future by ejecting any shared volumes before taking the actions described above.
If you accidentally trigger this issue, restoring connectivity to the server might eliminate the need for a forced restart.
