yeah thats the problem, we here supporting 100+ environment, without access to the box, only sysadmin access...making a check everyday to ensure all of them are in sync and basic configuration is not changes...ddl changes, security changes tracking are some of the tasks needed to ensure a good control...
as of now using sqlcmd to do this tasks...it was quite painful though
lets hope somebody has explored that option and have right solution...
