SYMPTOMS
Host-initiated password changes are not replicated to the Windows NT or Windows 2000 accounts database when you are using the password synchronization feature that is included with Host Integration Server (HIS) 2000. 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

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.

The following Knowledge Base article describes another problem that can occur with host-initiated password changes when using HIS 2000:
