I recently had a problem with replication where there were large numbers of Undistributed transactions/commands building up.
In Replication monitor, I right clicked my publisher and stopped and started synchronisation which cleared them all down and reset the undistributed transactions counter to zero.
I just wanted to know, are all of the undistributed transactions pushed through and applied to the other replicated databases or are these undistributed transactions lost forever?
What happens to them when Replication is re-started?
I'm using SQL Server 2008 R2.
