I have previously used HAProxy as a solution for this, and found it very simple and straightforward. Is there a similar product for windows (server 2003 or 2008) which provides similar configuration options and runs as a lightweight service?

Be careful, I've got very negative reports from people running Windows LB, which was the main reason why they switched to haproxy. If you're satisfied with haproxy, you can build it on windows using the cygwin suite. I have not tested it myself, but the user who performed the port did. He also told me that there was a limit to approximately 1600 concurrent connections per process under windows, which may or may not be enough for you.
From my understanding, the build should be as straightforward as on linux : "make". If you need more info from this user, I invite you to send a call on the haproxy mailing list. Alternatively, there are certainly people here on serverfault who can help with setting up a cygwin build environment. Please use version 1.3.22 (latest stable) for this.
I understand that the question is really old, but some people may still face the same problem. So the easiest solution is Cygwin. Example is here -haproxy-on-windows-cygwin-good-for-testing/#sthash.PhJ3odwn.dpbs
To define the IP address and port at which HAProxy should receive traffic, add a frontend section to your haproxy.cfg file. Inside this section, add a bind line. A bind line sets the IP address and port to listen on.
HAProxy generates logs in syslog format, on debian and ubuntu the haproxy package contains the required syslog configuration to generate a haproxy.log file which we will then monitor using filebeat.Confirm the existance of /etc/rsyslog.d/49-haproxy.conf and /var/log/haproxy.logIf you've recently installed haproxy you may need to restart rsyslog to get additional haproxy config file loaded.
The RPM haproxy default configuration sends it's logs to a syslog daemon listening on localhost via UDP. We need to configure rsyslog to listen on localhost and write a haproxy.log file which we will then monitor using filebeat. Run the following lines of command and then restart rsyslog.
Additional module configuration can be done using the per module config files located in the modules.d folder, for haproxy we want to configure the haproxy module to read from file, uncomment and edit the var.input line to say
Nginx vs HAProxy: I prefer haproxy over open source nginx in this exchange application scenario. Haproxy provides better load balancing, better logging and provides nice stats interface than nginx. TCP load balancing is not available in open source nginx but nginx plus does provide it. Nginx plus is a commercial one so you have to pay to get that feature. We can also monitor and visualize haproxy metrics stats in real time as well as through Grafana as new haproxy is built with the Prometheus exporter.
The term SSL Termination means that you are performing all encryption and decryption at the edge of your network, such as at the load balancer (haproxy). The load balancer strips away the encryption and passes the messages in the clear to your backend servers. This is known as SSL offloading. We can SSL offload at haproxy end and ignored SSL verification to internal backend mail servers. You can also store the CA certificate on the load balancer and reference it. Here, I have used both.SSL termination has few benefits. These include the following:
I am using haproxy version 2.0.13 on Ubuntu 20.04.1 LTS. We also tighten our TLS security by allowing only TLS 1.2 & 1.3.By default, Outlook clients 2010/2013 in windows 7 will try to connect exchange mail server through TLS 1.0 & TLS 1.1 so for that you have to do some changes in TLS part on your windows 7 pc. Windows 7 supports TLS 1.1 and TLS 1.2. But these protocol versions are not enabled on it by default. On Windows 8 and higher these protocols are enabled by default. Earlier I have written an article explaining enabling TLS 1.1 & TLS 1.2 in windows 7 pc. You can check this link if you are interested. -enable-tls12/

Introductionhaproxyadmin is a Python library for interacting with HAProxyload balancer to perform operations such as enabling/disabling servers.It does that by issuing the appropriate commands over the stats socketprovided by HAProxy. It also uses that stats socket for retrievingstatistics and changing settings.
haproxyadmin resolves this problem by presenting objects as single entitieseven when they are managed by multiple processes. It also supports aggregationfor various statistics provided by HAProxy. For instance, to report therequests processed by a frontend it queries all processes which manage thatfrontend and return the sum.
I can access the app server using this configuration, but the app fills some variables using the URL of the web browser, and as im accessing the app using another URL (haproxy.domain.name instead of the app server hostname) its causing some errors. Is possible to maintain the app server hostname on the url but also keep the SSL termination? The used certificate its a wildcard so adding the domain name would be enought (i think)
One thing to note: at the time of writing, HAProxy stable release 1.4 does not support SSL termination at the load balancer (there are 3rd party tools that can support them e.g. bundled with nginx). The newest version (in dev) now supports SSL offload capability therefore eliminating the need to install any components outside HAProxy to handle SSL.
This September 2021 cumulative update (CU) will install Exchange Emergency Mitigation (EM) service. This service is designed to help secure your servers that are running Microsoft Exchange Server by applying mitigations to address any potential threats against them. It uses the cloud-based Office Config Service (OCS) to check for and download available mitigations and to send diagnostic data to Microsoft.
In multidomain Active Directory forests in which Exchange is installed or has been prepared previously by using the /PrepareDomain option in Setup, this action must be completed after the /PrepareAD command for this cumulative update has been completed and the changes are replicated to all domains. Setup will try to run the /PrepareAD command during the first server installation. Installation will finish only if the user who initiated Setup has the appropriate permissions.
A component that's used within Exchange Server requires a new Visual C++ component to be installed together with Exchange Server. This prerequisite can be downloaded at Visual C++ Redistributable Packages for Visual Studio 2013. For more information, see KB 4295081.
After you install this cumulative update package, you can't uninstall the package to revert to an earlier version of Exchange Server 2016. If you uninstall this cumulative update package, Exchange Server 2016 is removed from the server.
Instrument your HAProxy instance quickly and send your telemetry data with guided install. Our guided install creates a customized CLI command for your environment that downloads and installs the New Relic CLI and the infrastructure agent.
Our guided install uses the infrastructure agent to set up the HAProxy integration. Not only that, it discovers other applications and log sources running in your environment and then recommends which ones you should instrument.

This configuration monitors multiple HAProxy servers from the same integration. The first instance (STATUS_URL: _haproxy-instance/stats) collects metrics and inventory, the second instance (STATUS_URL: _haproxy-instance/stats) only collects metrics.
The HAProxy integration captures the configuration parameters of the HAProxy instance. The data is available on the infrastructure Inventory page, under the config/haproxy source. For more about inventory data, see Understand integration data.
Ports. By default, AWS OpsWorks Stacks configures HAProxy to handle both HTTP and HTTPS traffic. You can configure HAProxy to handle only one or the other by overriding the Chef configuration template, haproxy.cfg.erb.
Note: Although supported, there is a known issue with HAProxy 1.8 that may result in performance issues when the Signal Sciences module is installed. HAProxy has fixed this issue with HAProxy 2.2, but the fix will not be backported to 1.8. It is recommended to upgrade to HAProxy 2.2 or higher if possible, or use an alternate Signal Sciences deployment method (e.g., reverse proxy agent if HAProxy 1.8 must be used).
