Error 0x80070057. Cannot install AePAgent. Cannot start service. The parameter is incorrect. (source=AePwd.PwdInstEx.1).

i'm working on my test lab but stuck with this error. not sure which part was wrong. Both source and target domain was established with trust (validate in place). as i also already disable SID filtering in both dc.

Domain acc used for domain pairing is set on Administrators group in mmad sever. No AV was installed and firewall is disable.

source dc is window server 2012 r2 and target dc is windows server 2016

even with SID History untick, the session still failed.

Anyone know what is wrong here?

password migration and sidhistory leverage an agent on the target. On the source an agent is used for password migration. The agent is failing to install, so that is why it is failing.There is an option to pre-install the agents documented in the product documentation. Use that and install the agent on both the source and target DCs AND set a primary DC/GC In the DSA agent manager for the domains. This should resolve this error.

hi Jeff,

Good day. Yes i did follow the preinstalled agent from this link Migration Manager for AD 8.15 - Granular Account Permissions (quest.com).

Set AllowAccess.ps1 for source dc and target dc. Restart server.

Set EnablePreinstalledMode.ps1 for mmad server. in Agent Manager, set preferred dc and gc for both source and target. Did not have any sync job

i did check on regedit:HLKM>Software>Aelita>MIgration Tools>Current Version>Password Agent, 'AllowAccess' key and 'PreInstalledMode' key is there.

Re-run the migration session, same error occured.

btw, how do i can attach pictures in this thread? doesnt seems can upload from computer.

Ok, this is your issue. You used a x64 version to PowerShell to run the EnablePreinstalledMode.ps1 script. The documentation clearly states you need to use the x86 version of PowerShell to run this script on the DSA server.

The key should really been visible in regedit:HLKM\SOFTWARE\WOW6432Node\Aelita\Migration Tools\Current Version\Password Agent key

Yes Jeff, you are correct. it was a mistake by not noticing it. i have applied the EnablePreinstalledMode.ps1 in powershellx86. it works perfectly now. Thanks
