How can I see how my mapped network drive is set up?

I support a number of users who all have mapped network drives set up
for accessing various servers. Most of these folks had the drive
mapped by someone else - usually someone from a helpdesk. Depending
on the user, they may or may not know what domain they belong to and
what their user id is. When one of these people needs to map a new
network drive or we need to disconnect and remap one, it would be
really helpful to be able to see what domain and account was used.
