Hi
In a domain environment, you haven't got a conflict really.

"Duplicate SIDs aren't an issue in a Domain-based environment since domain
accounts have SID's based on the Domain SID"

The only situations where identical computer SID can be a "problem"
(securitywise), is in a workgroup setting as well for removable media formated
with NTFS (where local account security attributes are applied to files and
directories).
