Lync Enable User problem (LookupUserConsole.exe)

Hi,

I have a problem with Lync 2013 and user enable. After a colleage brings up one template with the same domain computer account name of the Lync Server by mistake (actually the template machine was a clone of this Lync Server) things messed up.

After enabling an user by Control Panel or management shell,  I can see the details of the account with Get-CsUser command, but when I use the LookupUserConsole.exe I receive the message "UserDoesNotExist".

Can anyone help with this issue?

Thanks.
