John: 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. When an OpenAFS client built upon an native redirector is available for public use, then this problem will be resolved. When 1.7 releases begin to be issued, those releases will contain the AFS redirector. Jeffrey Altman
