Create custom wallpaper for your servers

I like to set the Windows Desktop to a specific color to easily identify it from other desktops I may have open. This way when I have multiple Remote Desktops running I can quickly see which one I need to click on. At a minimum I usually set the background color of the Desktop. Recently though, I started making custom images that I use as wallpaper that incorporate color idea and adds information to positively identify the server I am working on. []

Cannot login to Windows machine on vmware snapshot

In setting up a new SQL Server 2008 server in VMWare I created a baseline snapshot of the machine as it was before installing SQL Server. This way I could practice installing SQL Server refining the process with each installation. Today, I reverted back to my baseline snapshot and suddenly could not log in to the server using Remote Desktop.

How to start Prophet21 Acclaim

Today I needed to power-up our old Prophet21 Acclaim server to find some old information. It has been 7 years since we upgraded and the terminal connected to the machine did not work.

Use 7-Zip to install ISO files

Challenge: You download an ISO (like Office 2010 from Microsoft) but, cannot install it because your computer doesn’t have a CD-ROM.

Note: Windows 8 and Windows Server 2012 can mount ISOs to virtual CD drives natively but, Windows XP, Windows Vista, and Windows 7 cannot. However, Microsoft has created a utility to enable this functionality which can be downloaded from here:

Importance of monitoring

One day we noticed our Internet just wasn’t what we were used to. Although no-one was complaining we in the IT department were feeling it whenever we downloaded a large file like a Microsoft ISO. Fortunately, we had setup Cacti — a MRTG/RRD monitoring solution. A quick look at Cacti showed we were only getting about 3Mbs of Internet: Our Internet provider supplies us with a portal in which we can see our usage. Comparing our graph with their graph confirmed a []

How to edit client permissions in Exchange 2010

Aside from the GUI Exchange 2010 gives you two ways to assign client permissions — the permissions that dictate what end-users or clients can do — to Public Folders. One is a Powershell command that will apply permissions to a single folder. The other is a Powershell script that will apply permissions to a single folder and all subfolders. Command to add client permission to single folder: Add-PublicFolderClientPermission -User ‘mydomain\jchaven’ -AccessRights ‘Reviewer’ -Identity ‘\Management\Former Employee Mailboxes\John Doe\Calendar’ -Server ‘servername.mydomain.local’ Powershell script to []
