Duplicate machines using same GUID after imaging with PXE and WinPE

Issue/Introduction

I have six machines that were imaged via PXE and WinPE and the image was prepared with sysprep. 

For some reason they are all using the same GUID and as the Sym Agent on each machine attempts to do an update configuration it re-registers the GUIDs and "rotates" to the current device name in the SMP Console that is associated with the GUID in the database.  I have tried to place this GUID in the "itemtodelete" table and in the "agentblacklist" table then manually removed the agent and resinstalled it on several of the machines, and the GUID is always reassigned to it. I too used the /RESET GUID switch and this also didn't resolve the issue.  Not all machines that were created with this image are having this issue.

Environment

ITMS 8.x

Resolution

The following Powershell script resolved this issue on all machines (all remotely running elevated powershell):

Enter-PSSession -ComputerName {COMPUTERNAME}

Stop-Service -Name AeXNSClient

reg query"HKLM\SOFTWARE\Altiris\Altiris Agent” – check for “DsUniqueId” value and delete if there (none were present)

dir C:\Windows – check for AeXNSAgent.ini file

del c:\windows\aexnsagent.ini – (if present, and it was on all of these machines)

dir C:\Windows – make sure ini file is not present

cd'\Program Files\Altiris\Altiris Agent'

. .\aexagentutil.exe /resetguid

reg query"HKLM\SOFTWARE\Altiris\Altiris Agent" – make sure key now was “MachinePreviousGuid” to indicate will reset upon agent start

Start-Service -Name AeXNSClient
