When the shared key is used in authentication and encryption, why is the web authentication page not displayed and the message indicating the network is unavailable displayed after the user using the Windows XP system tries to associate with the network


By default, authentication packets sent from the Windows XP system are not encrypted. You need to manually set the authentication mode to shared key.

Another user has logged in to this ECS using VNC.

Only one user can log in to an ECS using VNC at a time. If multiple users attempt to log in to an ECS at the same time, only the first user can log in to it successfully. For other users, the system displays a message indicating that the user is authenticated, but the screen turns blank. If this occurs, wait until the other user logs out of the ECS.

The TE80 displays a message indicating a conference fails to be initiated.
If the TE80 displays a message indicating a conference fails to be initiated, the possible cause is as follows: The GK disables the HTTP port after HTTPS encryption is enabled for the SiteCall channel. If HTTPS encryption is disabled on the codecs, the codecs connect to the HTTP port. As a result, a conference fails to be initiated because the HTTP port cannot be connected. Solution: Ensure that the HTTPS encryption configuration is consistent between the GK and TE80 codecs.
