Error finding server old time capsule share name
I recently had to replace my Time Capsule and in setting the new one up I used a slightly different name for the share where the time capsule would back up my macbook. Now I keep getting a pop-up error to the effect of "The Server "XXXXX Time Capsule" server cannot be found. This may be because the server is unavailable or...." Well, it is unavailable because I have a new Time Capsule and I am using a different name for the backup share.
Can anyone help me so that this pop up goes away and the computer stops looking for a now-defunct time capsule share?
Airport Time Capsule 802.11ac, OS X El Capitan (10.11.4)
