Host Account Cache Requires Configuration of Master/Backup Role

RESOLUTION

An update to SNA Server 3.0 is available to correct this problem.

The SNA Host Account Cache service (for example, SnaDatabase) now regularly checks the following two conditions:

• It determines whether its role within the registry has been changed by checking the following registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SnaDatabase\ 
        Parameters\Master: REG_DWORD:  (1 = master, 0 = backup/secondary)
  					

• If determines whether the computer on which it is running has become a Windows NT PDC or has been demoted to a BDC.

If either condition is true (with the registry setting taking precedence), the SnaDatabase service performs an internal shutdown and restarts in the new role.

Also, the Host Account Cache role dialog has been removed from the Host Security setup script.

NOTE: The Snadatabase registry entry is not valid for SNA Server version 4.0.
