Hi,
Can you send following log:
DellConfigWizard.log
you can find this log in dsdp install folder
for example:
C:\Program files (x86)\Microsoft Configuration Manager\AdminConsole\XmlStorage\Extensions\bin\Deployment\Dell\PowerEdge
look for DellConfigWizard*.log
can you try DSDP 2.1 with DTK 4.2 and let us know the result:
