] I am very sorry you (and everyone else) are having issues with Windows
] 7.  The error you have received indicates that aklog has issued a pioctl
] to the AFS cache manager and it is unable to communicate with the
] service either because the service has not been started or because the
] SMB Netbios communication channel (Microsoft's code) has failed.
] 
] Network Identity Manager does try to provide you clear feedback on this.
]  There is a lock icon in the system notification area for AFS.
] If the lock is broken it means that the SMB Netbios communication
] channel has failed.  You can also tell that you have this issue if you
] issue the command "NET VIEW \\AFS" and it returns a System Error 53
] (Network Path Not Found).  If you receive error 53 and "nbtstat -S"
] indicates that the service "AFS" is listening, then what has occurred is
] that the Microsoft kernel module that performs Netbios name resolution
] is failing to identify the published name "AFS".  Unfortunately once
] this occurs there is nothing that can be done to regain AFS access but
] to reboot.

OK.  We will try to use this to diagnose, but in both cases (the 32 bit 
and 64 bit), rebooting had no effect.  ktc 7 still was the result.

More later.

Thanks,
John
