SYMPTOMS
Windows-based terminals or Windows clients may consume multiple Terminal Services CAL tokens because of local storage issues.



CAUSE
Windows-based terminals may consume multiple Terminal Services CAL tokens if the Terminal Services CAL token is not flushed to flash memory before the device is turned off. For example, if a Windows-based terminal connects for the first time and there are no Terminal Services CALs available, it will be issued a temporary Terminal Services CAL token. This temporary Terminal Services CAL token will allow the Windows-based terminal to connect for 90 days from issuance. After full Terminal Services CALs are available, the WBT will be issued one. If the device is turned off before the full Terminal Services CAL token has been flushed to flash memory, it will be issued a second full Terminal Services CAL token the next time it connects.

Windows clients may also experience this problem. For example, if a Microsoft Windows 98 client that has been issued a full Terminal Services CAL token does not work and is restored from a backup that was taken during the time that it had been issued a temporary Terminal Services CAL, the Windows 98 client will be issued a second full Terminal Services CAL token the next time it connects.
