We are deploying our ZCM10 agents to our workstations, are found that a
really few of them are randomly disabling the user/password field at the
login prompt, or when the workstation is locked. Windows XP sp2.

When this is occuring, we have no choice except to reboot the pc, and it
comes back ok.

The username/password are grey out...using the standart Windows Gina, no
Client32 here. it's really the first time I see this...
