NetApp: Unable to update SP network information at this time
edited by on October 9th 2017, at 11:20

The RLM module may become unresponsive and you may see the following messages in the Syslog:

Syslog
The software driver for the Remote LAN Module (RLM) detected a problem: Unable to update SP network information at this time.

You can resolve the issue by rebooting the RLM from the CLI.

Log on using the CLI (SSH or console), then reboot the RLM.

CLI: rlm reboot

Wait for a while and verify the RLM is back online:

CLI: rlm status

The output of the command should report: Status: Online

I got this through the contact form. It's a jargon-free guide to computer and internet security. It provides a detailed explanation on how to properly secure your computer and internet experience, and best of all, it uses simple and understandable language, lowering the bar for everyone to secure themselves against malware, ransomware and other malicious attacks.

Security Essentials on Windows Server 2012
edited by on October 6th 2017, at 12:49

Although unsupported, it is possible to install Microsoft Security Essentials on a Windows Server 2012.

To do this, set the compatibility of the downloaded file to Windows 7, then start that file with the parameter /disableoslimit.

The installation goes without a problem, and as far as I can tell, there are no compatibility issues.

 
Determine whether View Connection Server is standalone or replica?
edited by on September 28th 2017, at 14:36

If for any reason you need to determine whether a specific instance of VMWare View Connection Server is installed as a standalone server or a replica server, you can do so by looking into the registry.

In HKEY_LOCAL_MACHINE\Software\VMware, Inc.\VMware VDM, the value ServerInstanceType will indicate which type the CS is:

1 = standalone/first CS
2 = replica CS

Note that this doesn't really matter, as the only difference between them is whether they set up a new ADAM instance or connect to an existing one. After the installation of VCS, they are identical.

 
Quest Rapid Recovery: replication on unstable connections
edited by on September 21st 2017, at 09:54
Quest Rapid Recovery provides the ability to replicate restore points to off-site location. More than often, connectivity to these locations has limited bandwidth and is sometimes even unstable. Unfortunately, Rapid Recovery doesn't do well with unstable connectivity: more than often, replication jobs abort because of high latency. Luckily, you can tweak the timeout parameters through the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Core\CoreSettings\ClientTimeoutSettings Increase the values of ReadWriteTimeout and ConnectionTimeout to 1 hour.

HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Core\Replication\ReplicationService Increase the values of VolumeImageSessionTimeout and RemoteReplicat  ...

RPC over HTTP deprecated in Office 365 on October 31 2017
edited by on September 15th 2017, at 14:25
On October 31 2017, RPC over HTTP will be deprecated in Office 365, as stated here. This means that older Outlook versions (those that use RPC over HTTP) will no longer be able to connect to Office 365. The reason for this is that RPC over HTTP will be replaced in favor of the much newer MAPI over HTTP.

This switchover has an impact on all (older) Outlook versions that do not have the required update (incorporating MAPI over HTTP) functionality installed. Only Outlook versions that get this update will be able to connect to Office 365, resulting in the following changes:

Outlook 2007: no longer supported (there is no update).

Outlook 2010: only supported with SP2 and KB 2878264 installed   ...
 
How to disable Firefox insecure form warning
edited by on September 15th 2017, at 11:52
Firefox 52 introduced an insecure form warning: whenever a password is requested on a web form through a non-SSL website (i.e. no "https"), Firefox displays a warning popup below the focused field:

While the gesture is appreciated (user awareness and all), it can become annoying. There is a way to turn the warning off through the advanced configuration of Firefox:

Start up Firefox and enter the following URL in the address bar: about:config

You'll get a This might void your warranty! page. Click the I accept the risk! button to continue.

You'll get a list of everything there is to configure in Firefox. In the search bar, paste the following value to quickly locate the correct p  ...
 
Changing grayed out options in a DHCP scope (e.g. subnet)
edited by on September 15th 2017, at 10:06
Sometimes it may become necessary to make changes to a DHCP scope on your Windows DHCP Server. Unfortunately, for existing scopes, not all scope options are editable, and it can become quite a hassle to recreate the scope, especially when there are a lot of reservations. Luckily, there's a workaround which allows you to edit the scope options, which is by using netsh.

It is not possible for netsh to directly edit scope options, but you can create a dump of the complete scope configuration (including all reservations), edit the resulting file, and import it back into the DHCP server. For this to work, you'll need admin (elevated) privileges on the DHCP server.

Exchange mailbox delegations through Powershell
edited by on September 12th 2017, at 10:31

One of the most common Exchange admin tasks is setting mailbox delegations. Personally, I usually do this through EAC but once you're familiar with the Powershell counterparts, it can be quicker to use that instead. I've created this post as a reference to do just that.

In the reference below, the user "Ellen Somebody" requires access to the mailbox of "John Doe".

Send on Behalf

Set-Mailbox john.doe -GrantSendOnBehalfTo ellen.somebody

Send As

Add-ADPermission john.doe -ExtendedRights Send-As -user ellen.somebody

Troubleshooting AD account lockouts with NETLOGON logging
edited by on September 12th 2017, at 09:47
Occasionally, you may encounter AD account lockouts and the reason for the lockout is not always apparent. Enabling NETLOGON logging on your domain controllers may help in this regard. The NETLOGON log file will provide a detailed logging of all NETLOGON events and helps you to trace the originating device on which the logon attempts (and subsequent lockout) occurs.

To enable NETLOGON logging, run the following command (from an elevated command prompt):

nltest /dbflag:0x2080ffff

The parameter is a integer value of flags, and 0x2080ffff is the highest level, showing detailed timestamps, the domain controller clients authenticate against, client site, account password expiration, and much m  ...
 
Get Hyper-V to work in a VMWare virtual machine
edited by on August 23rd 2017, at 14:11

Hyper-V does not allow to be installed on a machine that's already virtual (such as on another Hyper-V or VMWare). For VMWare, you can circumvent this by adding custom configuration parameters to the VM's configuration.

Add these to the VM's configuration, either through the vSphere (web)client, or by directly editing the VMX-file:

hvh.enable = TRUE
hypervisor.cpuid.v0 = FALSE

If you're editing the VMX-file, you need to enclose the values (behind the =) in double quotes (").

 
Package repositories for old/obsolete Ubuntu releases
edited by on August 22nd 2017, at 15:09

Older, obsolete releases of Ubuntu are no longer available on localized mirrors. Instead, you must use the old-releases repositories. This is done by replacing the repository entries in /etc/apt/sources.list:

  • country.archive.ubuntu.com → old-releases.ubuntu.com
  • security.ubuntu.com → old-releases.ubuntu.com

For example:

us.archive.ubuntu.com/ubuntu/dists/natty/main/source/Sources

would become

old-releases.ubuntu.com/ubuntu/dists/natty/main/source/Sources

 
Drive in Windows still displays old size after extending the partition
edited by on August 22nd 2017, at 13:49
After successfully extending a partition on a VM, Disk Management shows the correct partition size but Explorer still shows the old size, even after a reboot.

The reason for this is that while the partition has been extended to the new size, the filesystem itself has not. Normally, Disk Management should first extend the partition, then the filesystem, but for some reason, the second part did not happen.

To resolve, perform an extension of the volume using diskpart.

Open an elevated command prompt and start diskpart (type diskpart and press Enter).

List all volumes to find out which volume number corresponds with the drive you need to resize: DISKPART> list volume

Shorewall not automatically starting on Debian 9 (and some versions on Ubuntu 16.04)
edited by on August 18th 2017, at 14:27
There's an issue with the Shorewall package in Debian 9 Stretch, causing Shorewall not to automatically start even when the required configuration files are in-place and/or modified. As stated here, the problem also exists on Ubuntu with some versions of the package (see article).

The problem lies with the package not enabling the startup script in systemd during installation. The solution is to manually enable this by running the following command (as sudo):

systemctl enable shorewall.service

This will enable Shorewall to automatically start during a reboot. Note that you will still have to set the correct parameters in /etc/default/shorewall (and possibly /etc/shorewall/shorewall.conf t  ...
 
Running T-SQL scripts with sqlcmd
edited by on August 9th 2017, at 12:20

You can easily run Transact-SQL (T-SQL) script files (with extension .sql) via the commandline utility sqlcmd:

sqlcmd -S Server\Instance -i C:\path\to\SomeScript.sql

By default, the output is written to the command prompt. You can also save the output to a file:

sqlcmd -S Server\Instance -i C:\path\to\SomeScript.sql -o C:\path\to\TheOutput.txt

Note that when using this, no output is written in the command prompt window.

Factory reset Samsung A3 (when locked out)
edited by on August 1st 2017, at 09:31
You can quickly reset a Samsung A3 smartphone by booting into recovery mode (e.g. when you're locked out):

Turn off the phone by holding down the power button (right side) and then select to power off.

Hold down Volume up, Home and Power buttons to power the device on. Keep Volume up and Home down until you see the Samsung logo. After a while you will get the recovery menu.

Use the volume buttons to navigate in the menu (up for up, down for down). Select wipe data/factory reset, then press the Power button to confirm. Use the same keys to select yes if an additional prompt appears.

The reset takes a very short time after which the recovery menu will be displayed again. Either select rebo  ...
 
Adding file extensions to the list of safe extensions in Safari (on Mac)
edited by on July 28th 2017, at 10:31
Safari has an option to automatically open files that are considered "safe". Usually these are document types (e.g. PDF) but sometimes it may become necessary to add other file extensions that are not considered "safe" by default. This can be achieved easily by adding/editing a plist configuration file to your profile (i.e. user-based setting).

The preferences file is located at ~/Library/Preferences/com.apple.DownloadAssessment.plist, and determines whether a specific file extension is considered safe or not.

If the file does not yet exist, create it with the contents below:

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.ap  ...
 
Error 'VIEW SERVER STATE permission was denied' when connecting to SQL 2014 using SSMS 2012
edited by on July 26th 2017, at 12:30
When attempting to connect to a SQL Server 2014 or SQL Server 2016 using SQL Server Management Studio 2012, you may encounter the following error:
