I doubt i understood your question: if so try to explain your needs in a more accurate way.

From what I understand you connect to a server share, let's say \\10.10.10.10\share_name rigth? Now you want to know this share what path holds on the target server? Like c:\stuff\shared

If my assumptions are correct you can wrap some perl code around wmic /node:10.10.10.10 share get name,path command.

Like:

my $remote = '10.10.10.10';
my $share = 'share_name';

# connect to the share..
...
# get info on the share from remote system

open my $cmd, "wmic /node:$remote share get name,path|" or die;

while (<$cmd>){
  chomp;
  my ($got_name, $got_path) = split /\s+/, $_;
  if ($got_name eq $share){
    print "share [$share] at $ip is remotely: $got_path\n"
  }     
}

This thread discusses this topic how to list all the drive letters.

does it?

I probably should have asked the OP to specify if they wanted to get the drive letters for mapped drives. That's how I interpreted the phrase "top level directories". What is your assumption of what the OP meant?

use IPC::Run3 qw(run3);
run3 ["NET","VIEW","\\\\servername","/all"], undef, \$stdout;
die $? if $?;
print "Output:\n$stdout\neof\n";

I don't think that will get the volumes per se, just the named shares.

volumes? show me where the OP said something about volumes. OP said

I'm looking for a method where I can ask each server for it's top level share names.
