Microsoft Outlook No Previewer Installed

4/14/2017

If Outlook says "This file cannot be previewed because there is no previewer installed for it" when you are trying to preview an attachment, this means that file type has no default program associated with it.  Try saving the attachment and then choose Open With... to associate a program.  After that, Outlook will use that program to preview attachment of that file type.

Symantec Endpoint Protection and Remote Desktop Server performance

4/14/2017

We had a customer who was experiencing slowness on their terminal servers and the slowness was keeping some reports in their core banking application from running.  We found that when we excluded the entire C: drive of the terminal server from all Symantec Endpoint Protection scans, the errors would not occur. Through trial and error, we tracked down the setting in SEP that was causing the performance problems. We changed the “Scan files when” setting from “Scan when a file is access or modified” to “Scan when a file is modified”. This solved the performance issues and reports in their core banking application are running properly now.

Hidden CLI on Cisco/Linksys Small Business Switches

4/14/2017

The Cisco-Linksys SRWxxxx series of switches have a simple web interface for management purposes. The interface lacks the ability to see the MAC address table. You can SSH or telnet to the switch, but the menu you get is no better. However there is a hidden CLI (called the lcli, I assume that stands for Linksys CLI) you can access that will allow you additional management capabilities. Once you are logged into an SSH or telnet session and are at the menu, do the following:

Change OneNote Default app in Windows 10

4/14/2017

Windows 10 ships with the OneNote app. If you also have OneNote 2016 installed on your computer, you will end up having two OneNote applications installed. The Windows 10 OneNote app is quite often set as the default version, so when attempting to follow a link from someone else, the Windows 10 OneNote app opens and asks you to log in. People who are familiar with OneNote 2016 are completely lost and stuck at this point.

What is Vendor Risk?

3/15/2017

  Assessing risk is all about extrapolating meaning from potential. In other words, look at what could happen and consider how those things would affect you. The process can be as complicated or as simple as you choose to make it. At the end of the day, risk assessments are a way to become aware of potential issues and of controls to alleviate those dangers. You do not have to think of every potential scenario. In fact, considering what is common covers the majority of threats.

Keep Calm and Plan for Incidents

3/13/2017

  Floods. Hurricanes. Tornadoes. Fire. Power outages. The zombie apocalypse (well, maybe not that one). You don’t have to be in banking to know these threats exist in our world. Although they may not have an exhaustive, board approved Business Continuity Plan ready to go in an emergency, the average person has some awareness that disasters occur and an instinct on what to do:

Exchange Dynamic Distribution Groups

3/2/2017

While working with a customer who was searching for a solution to help manage distribution groups, I discovered that Exchange provides a feature called Dynamic Distribution Groups. These groups allow you to set up the distribution group, and then create a rule that references something like an OU or an AD account property to define which users belong to that group.

VMware vCenter appliance alert emails

3/1/2017

I recenly rebuilt a vCenter environment for a customer. We decided to use the vCenter Server Appliance 6.5. The configuration of the vCenter Server Appliance was fairly simple and operates very similar to vCenter Server installed on Windows. We attempted to setup email alerts, but were unable to get the alerts to send. We initially thought the alerts would not send due to an issue with the SMTP relay. Since this was not a Windows OS, I was not able to login to the OS and test the STMP relay using telnet. I checked my configuration of email alerts several times and the administrator of the SMTP servers checked his as well and everything looked correct on both sides, but emails still would not send.
