smb folder aliases (shortcuts) not working reliably

Clients are 10.3.9
Authenticated to AD, single signon.
I have created aliases to network space via:
Go– Connect to server: smb://server/share/folder
I drag “folder” to the desktop holding down cmd-option to create an alias
This alias works great– anyone who logs in can dbl-click it, and it mounts the network share using their kerberos ticket. The problem is when the user, for whatever reason, disconnects/ejects the network share. If they click the shortcut again, they get a message that the alias is broken, and a prompt to fix it, etc. They have to logoff/back of in order to fix it (or do Go–Connect to server, etc)…

It’s as if part of the Finder doesn’t realize that the fileserver was unmounted, and it’s looking in /Volumes/server/folder and not automounting it…

Any ideas?
thxx!
