Handling cloned computers

Suppose you want to have cloned computers in your network where ESET Secure Authentication On-Prem (ESA) will be used. In that case, the attributes below must be unique for each computer to be protected by ESA.

•For correct registration of ESA components (Windows Login plugin, Remote Desktop plugin), which communicate in Active Directory Integration mode with the Authentication Server:

▪Computer name

▪Computer SID

▪Computer AD object SID

•For correct registration of ESA components (Windows Login plugin, Remote Desktop plugin) that are installed in Standalone mode:

▪Computer name

▪API username in C:\ProgramData\ESET Secure Authentication On-Prem\ESA.config

•For correct registration of realms for local users:

▪Computer name

▪Computer SID

Use Microsoft's SysPrep tool to ensure unique attributes are applied to cloned computers.

1.In the SysPrep, use the Generalize option to create a generalized Windows image to be cloned later. Each image is configured during its first boot.

2.If the cloned computers are used in a domain:

a.On the cloned machine, run the SysPrep tool.

b.Reboot the computer.

c.Connect the computer to the domain.

3.Install ESA (Windows Login plugin, Remote Desktop plugin) to each cloned computer either manually or through GPO.
