Hello, I have a Network with two Windows 2000 server , I suppose one is master (or primary) and one is secondary - I don't know exactly the vocabulary of Windows. the AD is "replicated" over the two Windows Server I installed synchronization between the FDS server and the AD on a host (say Windows-1 server), with Agreement replication then I installed the password sync on the Windows-1 host. All is ok when the password is changed on the Windows-1 server, the password is synchronized to the FDS. Now when a user change his password on a windows XP station in the AD (the operation is CTRL+ALT+DEL then change password) the password is not necessary sync to the FDS. my hypothesis : it seems it depends on which windows server the password has been changed. Some time the password is sync when, I suppose, the Windows1 server answer to the request to change the password, but when the windows2 server answer , then the password is not sync. is my hypothesis correct ? Can I install the password sync programm on the other Windows2 server even if the replicated agreement is beetween FDS and Windows1 server ? wich will behavior be ? thanks -- Jean-Noel Chardron
