I setup merge replication across a publisher and 50 subscribers using a common domain account. The account isn't just used for that service, however. (I made a bad choice from the get-go, in other words!)
It hasn't happened yet but there may come a time I need to suddenly change that account password - which would (I'm sure) bring merge replication to an absolute halt. Is there a way (without dropping and re-establishing replication) to modify the username and password used?
