setspn list problem

[Billie]

I am getting an invalid DN syntax if I am using setspn -L domain\usernam on certain accounts, but not others? I have checked on these same accounts that dont work with setspn -L; they do work with adding a SPN. It usually responds "updated object" and then via LDP.exe I am able to check that indeed an SPN has been set? Thanks for any help.

The below document has a detail information on all the aspects of setspn. You must also go through some ready to use sample scripts that can reduce your work to an extent.
