Install certificate in Exchange 2007

 I recently had to renew my Exchange certificate as it expired. The original admin that set up this Exchange bought the previous certificate from Digi. I decided to go with Startcom (Free SSL) as I have used them once before in an OCS deployment and they worked out well. Exchange is a little different in that you must use Exchange management shell (PowerShell) during the process of installing a certificate for Outlook Web Access (OWA). I am going to cover 5 steps to installing a certificate Exchange for OWA.

 To Open Exchange Management Shell: Go to START >>Programs>>Microsoft Exchange Server 2007 >> Exchange Management Shell

 

This is the management shell

GPO disabling a Windows service

I would then reboot the VM. The DHCP client service would be disabled again. I had a feeling … Read more

Show hidden devices in Windows

Have you ever had devices that where stuck on your system and you needed to remove them. For example someone removed a physical network card from the system without uninstalling it first from the OS. This can be a problem if that network card had a static IP assigned to it. Once you add a new network card using the same static IP that was assigned to the previous network card it will give you an error.

If this were to happen normally you would go to device manager and simply uninstall the device. Well what if they don’t display? That means they are hidden. It is a good thing there is a way to un-hide them so you can uninstall them.

I have created a batch file that contains this:

ISA 2006 blocking FTP traffic

My clients on my network could access FTP servers behind our ISA 06 firewall but they could not create or delete anything on that FTP. I checked to make sure the permissions on the FTP were setup correctly. I narrowed it down to ISA blocking Incoming FTP traffic coming back from the FTP servers. I did some searching and there are many issues out on this. Others issues vary slightly but I did find something that worked for me. I setup the below rule on ISA.

Manually install a DPM 2007 agent

I ran into problems installing DPM agent on a few of my servers over the network through the DPM admin console. In this case I had to manually install the DPM agent on the servers I wanted to protect. Here are the 4 steps:

1. Locate the 2.0.5820.0 folder on your DPM server here in:

%systemroot%\Program Files\Microsoft DPM\DPM\Agents\RA\

The 2.0.5820.0 folder is here and will have folders i386 and amd64 in it. If you are installing on a 64bit server use the installer from the amd64 folder otherwise just use the i386 folder.

2. Copy to this folder to the local %systemroot% drive on the server you want to protect. I created a folder in on the server I wanted to protect to make things easy called DPMagentinstall
for example c:\DPMagentinstall

3. Open a command prompt. If this is Windows 2008 server be sure to open the command prompt with elevated privileges. Then type: CD c:\DPMagentinstall\DpmAgentInstaller.exe YOURDPMserverFQDN

EXAMPLE: DPMAgentInstaller.exe DPM01.mydomain.com

It will then let you know that your server requires a restart if it was successful.

How to save credentials for a maped drive

Have you ever mapped a drive and chose to have it Reconnect at logon but it did not save the credentials? This has happened to me. The end user has to call you again and again to re-enter the credentials in for them. There are two ways to fix this.

 

You can use “savecred“. Savecred will save the credentials permanently. The other option is to use “manage passwords” that come with XP in control panel.  Manage passwords will only save the password for the current session once the user has typed the password in after being prompted for it. Here are the work arounds:


OPTION 1: “Manage Passwords”

Map your drive:

  • Go to My computer/Computer
    Click on tools then select map drive
  • Type in the UNC (\\server\share) that you want to map
  • Check the box that says reconnect at logon
  • Then click on the connect using a different user name
  • It will prompt you for the credentials. Type these in and click ok
  • Now click finish and the drive will be mapped using a set of different credentials then the user you are logged in with
