The HIS 2000 host security components will log event 1301 messages similar to the following when this problem occurs: Event ID: 1301 Source: SNA Host Security Description: The database received a request it did not understand Supplied code %1 Event ID: 1301 Source: SNA Host Security Description: The database received a request it did not understand Supplied code, send UdiChPwdRq to Mdb failed Event ID: 1301 Source: SNA Host Security Description: The database received a request it did not understand Supplied code, HprReplicatedUpdate Failed Event ID: 1301 Source: SNA Host Security Description: The database received a request it did not understand Supplied code, HPR_CHANGE_PASSWORD_REQUEST NOTE: The event 1301 messages will be logged in the Application Event Log on the Windows NT 4.0 Primary Domain Controller (PDC) or Windows 2000 PDC emulator where the SNA Host Account Cache and SNA WinNT Account Synchronization services are installed. CAUSE ===== The SNA Host Account Cache (SnaDatabase) service fails to obtain the Windows NT or Windows 2000 domain name prior to validating the length of the domain name. This results in the event 1301 messages and the failure to update the user's Windows NT or Windows 2000 password.

STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Host Integration Server 2000. MORE INFORMATION ================ The HIS 2000 Host Security Integration feature supports one-way host-initiated password synchronization to IBM mainframes and AS/400s. Environments that perform host-initiated password synchronizations require a third-party password synchronization application in addition to the HIS 2000 Host Security Integration components.
