End-user Access
Endpoints Supported
NOTE:
TIP:
5-6
Other operating system support (for example Linux) will be included in future
releases. Windows ME and Windows 95 are not supported in this release.
If the end-user switches the Windows view while connected, such as from
Classic view to Guest view, the change may not be immediate due to the way
sessions are cached.
