When you open multiple Properties windows for the wireless connection in Windows Vista, you may receive the following error message:

Windows has encountered an error saving the wireless profile.
Specific error: An attempt was made to establish a session to a network server, but there are already too many sessions established to that server.

For example, this problem may occur if you open the Network and Sharing center, and then you click the network icon for the wireless connection many times.

Note: If you have multiple Properties windows for the wireless connection open, and you make changes in more than one page, the only the changes that are retained are the ones that you make in the last window that you close.
