IIS Client Certificate Revocation Check Disable

Image
A couple of weeks back, a certificate was approaching it's expiration date on an IIS server and the update - although pretty straight forward, caused a major issue for the service running on that server.

I had the new certificate in PFX format, I've installed it on the computer certificate store and it was available in the IIS Manager console. All the certificates for the Root and Intermediate authorities were property installed and the clients had access to the CRL urls.

However, when I switched the certificate, the clients were not able to communicate property with the website. After going through the logs on the clients and the application, I discovered that the clients were using client certificates in order to authenticate and the validation process was failing for those certificates since my server could not check their revocation.

I opened up a command prompt to get more information on the bindings on the website since there are settings that are not available when usin…

How to Configure Message Forwarding on a Mailbox Level

Image
The Set-Mailbox cmdlet has two parameters to configure forwarding for a mailbox: ForwardingAddress and ForwardingSmtpAddress. Those two parameters serve the same puspose but in two different ways. There is also a third parameter called DeliverToMailboxAndForward that when set will leave a copy of the message on the mailbox.

The "ForwardingAddress" accepts RecipientIdParameter input which means that you have to use the identity of an existing object on your organization such as another mailbox or a mail contact.

The "ForwardingSmtpAddress" accepts input in a proxy address format such as plain old email addresses. Although this is pretty straight forward, there's a catch you need to be aware of. This will only work if the remote domain of the recipient is configured to allow message forwarding. Let me elaborate.

There's a thing on Exchange, called Remote Domains. Those are used in order to define settings for the communication between your Exchange server and…

Syslog Message Collection for OMS from sources that do not support the agent

Image
On the previous article of the OMS series, we've installed and configured the OMS agent on a linux machine and started collecting syslog messages and performance statistics.

Today, we are going to use that machine to collect syslog messages from other machines, devices or applications that are not supported by the OMS agent. This is a two step process, first we are going to enable the remote syslog collection on the linux machine and then we are going to update the configuration of the agent to support high volume of syslog traffic. Let's dive in!

The syslog server is going to be rsyslog since it came with Ubuntu server and the configuration file is stored at /etc/rsyslog.conf.

To enable the remote collection, the below lines have to be uncommented in the configuration file:

module(load="imudp")
input(type="imudp" port="514")
and
module(load="imtcp")
input(type="imtcp" port="514")

Since we are going to be collecting messa…
