Error: cannot add duplicate collection entry
I got this weird error message while I am performing an operation on enterprise vault server, unable to expand EVAnon virtual directory in IIS Manager. It shows error “There was an error while performing this operation” I think I made something wrong while configuration with IP address and Domain restrictions with Enterprise Vault virtual directory. Please help me to fix the problem. Thanks in advance.
