I have a new computer which has the same name as a very old computer that has not existed for many years.
I am trying to install Sophos via the Enterprise console but cannot as despite deleting the original computer, when I re-discover computers it somehow picks up the old one, not the new one.
I can tell it is the old one as it is greyed out and the details say it is Windows Vista (the new on is Windows 10). This old one hasn't existed on AD for at least 10 years.
When we change computers we have regularly re-used names without a problem so I don't know why this one should be different.
I have read some stuff about the SEC keeping hold of info in the database even when computers are deleted and some people said there is a workaround to delete them completely but it was a thread from about 10 years ago and I didn't know if it was still relevant and it wasn't clear what to do.
I know an easy solution would be to give the computer a different name, but would prefer the current name if possible, and would like to understand why SEC does not delete computers when they are no longer in AD, and if there is a way to delete them that could be explained in fairly simple terms.
