There are times when we need to perform database maintenance on The Raiser's Edge running on SQL Server 2008 R2. This maintenance includes tasks such as having a third party reconcile the mailing addresses and update them as appropriate. At present, during that maintenance window we tell users not to login to RE and hope they remember. We need a way to, at the software level, deny users from logging in to RE during maintenance. I looked at SQL Server itself and it doesn't seem to expose the actual RE users, where you could run a SQL command to disable or enable the login. Blackbaud Management Console doesn't have that ability, though it would be a natural spot for Blackbaud to add that functionality.
