When I was installing Cygwin under Windows 2012 I met trouble with connecting to SSH-server. Every time I tried to connect to server via SSH I got messages "Operation not permitted" and "Connection closed".

editrights -l -u cyg_server
By next commands you can add missing rights:
editrights -a SeAssignPrimaryTokenPrivilege -u cyg_server
editrights -a SeCreateTokenPrivilege -u cyg_server
editrights -a SeTcbPrivilege -u cyg_server
editrights -a SeServiceLogonRight
