New account in Outlook still tries to use on-premise Exchange after migration to Office365
edited by on June 30th 2016, at 13:11
When you migrated your mail from an on-premise Exchange to Office 365, and you did not (yet) uninstall Exchange and/or clean up AD, Outlook will still try to configure itself to connect to the on-premise Exchange when adding a new account, even though Autodiscover has been configured correctly (autodiscover.domain.tld pointing to autodiscover.outlook.com).

The reason for this is in the way how Outlook performs its autodiscovery attempts. The first step in the discovery process is trying to configure the account using Service Connection Point (SCP), which is defined in AD (or in rare cases, in the registry of the computer). As the SCP is still configured in AD/registry, Outlook will use thos  ...
 
Uninstalling a specific Windows update through command line
edited by on June 27th 2016, at 09:42
If you're looking to uninstall a specific update, you'll find that it's quite tedicious to do this via the GUI. It shows an endless list of updates and it's very difficult to find the right one through its KB number. Fortunately, you can also uninstall updates from the command line, by specifying only its KB number, which is veeerry useful indeed.

Open an elevated command prompt and run the following command to uninstall an update by its KB number:

wusa /uninstall /kb:3035583

Replace the number with the number of the KB you wish to uninstall (the line above would uninstall the Windows 10 Upgrade prompt).

You can also add additional parameters:

wusa /uninstall /kb:3035583 /quiet /noresta  ...
 
Error "Destination path not empty" when upgrading an AppAssure/Dell Rapid Recovery Agent
edited by on June 21st 2016, at 15:47
For some reason, if an upgrade of an AppAssure/Dell Rapid Recovery Agent is not succesfully completed or cancelled, a subsequent upgrade may fail with the following error message:

Error
Destination path is not empty. Please choose another one.

If an upgrade was cancelled or has failed for some reason, the following upgrade attempt will try to perform a complete installation. Because not all files and/or folders have been removed, the installer will not continue and will display the error message.

To resolve the problem, manually remove the files and folders, but leave any registry keys intact to ensure a proper upgrade without losing any settings.

If it is running, stop the Agent or Core  ...
 
Renewing an Exchange SSL certificate through an internal Certificate Authority
edited by on June 21st 2016, at 15:31
Even when using Exchange SSL certificates that are signed by an internal CA, you will still occasionally have to renew them. Using EAC (https://your-exchange-server/ecp), this should be pretty straightforward, or is it?

After logging on to EAC, and navigating to "Servers" → "Certificates", select the expired certificate, then on the right pane, you can click "Renew" to generate a certificate signing request with all the proper SANs. This CSR can then be used with your internal CA to sign the request and generate a new certificate.

Unfortunately, you will most likely hit a snare: the CSR generated by the Exchange server does not contain any certificate tem  ...
 
Upgrading AppAssure to Dell Rapid Recovery
edited by on June 20th 2016, at 15:13
Dell has changed the name of its acquired AppAssure to Dell Data Protection Rapid Recovery. AppAssure (latest version is 5.4.3) is no longer being maintained, so upgrading to Rapid Recovery (latest version 6.0.2 at the time of writing) is a requirement for continued support. Fortunately, performing the upgrading is not really difficult, and can be done without too much downtime for your backup.

Additional information, including a compatibility and upgrade matrix can be found here:

How to Upgrade AppAssure 5.4 to Rapid Recovery 6.X (181997)

Dell Support Policy (compatibility matrix for Core and Agent versions)

At the time of writing, the compatibility matrix shows that Agent version 5.4.3  ...
 
Prevent .DS_Store file creation on network shares
edited by on June 9th 2016, at 16:31
Mac OSX creates .DS_Store files on network mapped folders to store metadata (such as position of icons, added comments on files and folders, etc.). On a local (Mac-formatted) disk, these are stored as filesystem metadata, but on network folders, this is not possible, so this data is stored in a file instead. While this file is hidden for Mac-users, Windows-users will immediately spot the file in each folder that's accessed by a Mac. The creation of these metadata files can be turned off for network shares on SMB/CIFS, AFP, NFS, and WebDAV servers.

Open a Terminal, and run the following command:

defaults write com.apple.desktopservices DSDontWriteNetworkStores true

This is a user setting s  ...

Decrypt Cisco IPSEC VPN group password from PCF file
edited by on June 7th 2016, at 15:47

If you lost your group password from the Cisco IPSEC VPN but still have the PCF file, you can use this website to decrypt the encrypted password, located in the file. This is useful if you need to manually configure your VPN client (e.g. on a Mac, you cannot import a PCF file with the native VPN client).

https://www.unix-ag.uni-kl.de/~massar/bin/cisco-decode

To get the encrypted password, open the PCF file with a text editor (such as Notepad), then look for the line starting with enc_GroupPwd=. Copy everything after the = (if you have wordwrap on, make sure you got the entire line), and paste it in the text box on the website, then click the Decode button.

 
Using one RDS WebAccess and Gateway for multiple RDS farms
edited by on June 6th 2016, at 16:24
While not recommended, it is possible to use one RDS gateway for multiple RDS farms, each with their own broker. In this case, the RDG must use the same FQDN in all deployments, and you should only make changes to its configuration from only one of the deployments.

In 2012, it is not possible to use one RDS WebAccess to service multiple brokers. It can only be used on a single deployment. Attempting to add the WebAccess server to another deployment will overwrite the configuration of the first deployment.

A better approach would be to create a single deployment with an RDS WebAccess, RDG and broker (single or HA), and add your "different deployments" as collections to the broker.  ...

Note: this original post was from May 2007 but someone pointed out to me that the link no longer worked, in an attempt to sell me some web hosting... So... Thanks, but I'm sticking with my current hosting company.

Internet Explorer 8 for Windows XP and 2003 download links
edited by on May 23rd 2016, at 15:27
Internet Explorer 8 is the last version for Windows XP and 2003, but with them no longer being supported, the download links have been removed as well, making it difficult to download and install it. Although XP and 2003 are quite outdated, certain scenarios still require the use of XP and/or 2003.

A default install of XP/2003 contains Internet Explorer 6, so not being able to download IE8 would result in those systems running an even more outdated and unsecure browser. While IE8 isn't that much better, I consider it a tiny bit more secure, hence this article...

For the moment, the standalone installation files still exist on the Microsoft servers, but they are no longer linked to from the  ...
 
Add a second IP address on the LAN interface (no VLAN) on Sonicwall
edited by on May 18th 2016, at 16:09
You can add a secondary IP address on any interface (e.g.) without using VLAN tagging. This is useful if you have more than one subnet on your LAN, have no VLANs but want both subnets to be routable, without using an additional physical interface.

Create a static ARP entry for the gateway address of the additional subnet on the interface. Select the interface on which the subnet will be on. Enable Publish ARP. This will also automatically fill in the MAC address of the selected interface.

Create an address object for the additional subnet.

Add a static route for the additional subnet:Source: ANY

Destination: the address object you created in the previous step.

Service: ANY

Gateway: 0.0  ...
 
Lock and Sleep keyboard shortcuts for Mac
edited by on May 15th 2016, at 12:31
Control + Shift + Eject*Locks your Mac so you will have to unlock it with your password. Note that this will also sleep the display but the Mac will continue to run.
Command + Option + Eject*Puts the entire Mac asleep. This is the same as clicking on the Apple-icon at the left-top and choose "Sleep".

* Newer Macs: Eject = Power

To properly "lock" your Mac when using either of the shortcuts, you will have to enable Require password after sleep or screen saver begins (System Preferences → Security & Privacy). When not set to immediately, the configured delay will be used when using the shortcuts.

 
Set a wallpaper on Mac OSX with Terminal
edited by on May 10th 2016, at 09:52

You can use Terminal in combination with AppleScript to set/change the wallpaper on your Mac. While not immediately obvious when you would need this, it might come in handy for automation purposes.

Open a Terminal and run the following command:

osascript -e 'tell application "Finder" to set desktop wallpaper to POSIX file "/path/to/file.jpg"'

Replace /path/to/file.jpg with the full path of the file you want to use. All common formats (JPG, PNG, etc.) are supported.

 
Aerohive: upload captive portal files fail (scp error)
edited by on April 28th 2016, at 15:11
When pushing out the configuration from the HiveManager to Aerohive APs, and you have one or more captive portal in use, the update may fail with an error about unable to upload the captive portal files. The detailed error message reveals a problem with SCP (such as not enough free space to store files).

The problem is that the "web-directory", a local folder in the AP is taking up too much space on the flash memory. You can completely clear the folder through the CLI, then have the update put the captive portal files back.

Log on directly to the access point with SSH, using the device admin user and the CAPWAP password you specified in the HiveManager.

Accessing encrypted DMG in Windows
edited by on April 26th 2016, at 16:56
If you have an encrypted DMG on Mac and you need to access the contents on a Windows machine, you can use HFSExplorer!

Similar to Microsoft's Bitlocker, you can also encrypt entire drives/partitions with a high-grade security algorithm. And just like Bitlocker can encrypt virtual harddisks (VHD), Mac can encrypt volumes stored in a DMG. Out of the box, the two technologies are not at all compatible. But there are some third-party tools out there which allow you to access encrypted DMGs from Windows.

HFSExplorer is an open-source utility on Windows which can open any type of DMG and also supports opening encrypted DMGs. To install the software, you will need to have 32-bit Java installed (d  ...
