Change Connected Servers I have two Synology Diskstations in my list of Connected Servers. Disk station-5 and Diskstation-8 (see image). Now I want to change the user name for these connected servers and I want these connected servers to connect when I boot my laptop or desktop. I simply cannot get it done. Every time the servers are not connected and when I try to connect the old user name appears. Anyone ?
Make sure the password is cleared in your login Keychain. Open the Keychain Access utility (spotlight > Keychain Access). IN the left hand panes, select Keychains > login and Category > All items. Now search for diskstation in the top right to filter the results.

Delete the offending keychain entries.

Change the username and password for these entries so as not to disrupt anything else going on with those servers.
