If server B can run CGI scripts it is really easy. On server b put this in the cgi-bin 

#/usr/bin/perl -w
use strict;
use CGI;
my $q = new CGI;

print $q->header();
# my $caller = $q->remote_host() so you know who called you
my $err = do_something()
print $err ? $err : "OK";

sub do_something { ... }

Then all server A has to do is call the script (assuming server b is at IP 192.168.0.123: 

#!/usr/bin/perl -w 
use strict;
use LWP::Simple

while (1) {
    if ( some_event() ) {
        my $response = get('http://192.168.0.123/cgi-bin/server_b_scri
+pt.pl');
        warn $response =~ m/OK/ ? "Notified server b OK\n" : "$respons
+e\n";
    }
    sleep 10;
}

# check for some event
sub some_event { ... }

Using Apache/IIS and CGI is a simple solution as you already have a server listening on port 80 on the remote machine. If you don't have this facility you essentially need to have a server script listening on a port on server b and a client on server a. There are plenty of examples of this on the site. Depending on the OS there may also be other ways to do it using native OS utilities.
