SYMPTOMS
If the drive being mirrored is the boot drive and contains only one partition, fault tolerance in LAN Manager versions 2.1a and 2.2 does not properly recover from a crash of the primary drive. Running FTBOOT.EXE on the mirrored drive does not configure the drive properly and the system hangs when you reboot.



CAUSE
Earlier versions of FTBOOT were not tested for the case of one primary partition and no extended partitions. The pointer to the extended partition was not cleared, which corrupted one of the internal records that fault tolerance uses and in turn affected DISKFT.SYS.



RESOLUTION
Microsoft has confirmed this to be a problem in LAN Manager versions 2.1a and 2.2. This problem was corrected in the latest US Service Pack for LAN Manager. For information on obtaining this update, query on the following word in the Microsoft Knowledge Base:
