Re-cycling an SBS 2008 SSL Certificate on a WatchGuard Firewall

I recently rolled out the SSL VPN feature on my WatchGuard M200 Firebox. This will replace the SBS 2008 PPTP VPN for Mobile Users. PPTP is no longer regarded as secure. The SSL VPN itself works fine, but the SSL Certificate is "self generated" by the Firebox, so users receive a security warning when they …

Office 365: Your Automatic Reply Settings Cannot Be Displayed

We recently decommissioned our aging Exchange 2007 Server and switched to using Office 365 for Email. One quirk of the new system was that some users were having difficulty accessing their Out Of Office (Automatic Reply) Settings when using Outlook 2010 or 2013. Your automatic reply settings cannot be displayed because the server is currently …

Watchguard Firebox M200: Unblocking WeTransfer

If you are blocking "Personal Network Storage and Backup" at your Watchguard Firewall, users won't be able to access wetransfer.com. In their own support documentation here, WeTransfer suggested creating the following firewall exceptions: *.wetransfer.com *.we.tl *.amazonaws.com *.wetransfer.net However, this still doesn't prevent the Firebox from dropping the traffic.

Essentially, this is to allow multiple versions of SQL Server to happily co-existing on the same server. The table below lists the default file locations …

XAMPP: Using MySQLDump to Backup MySQL on Windows Server 2003 and Windows 7

I couldn’t find anything specific for Backing up the MySQL Databases within XAMPP. There certainly isn’t a pre-configured routine available. In addition, MySQL Workbench (unlike its predecessor MySQL Administrator) does not provide any automated backup facility. So, I decided to explore the use of “MySQLDump”, a command line routine that can be inserted into a …

Fitting USB3 into a DELL PowerEdge R510 Server

USB3 is not supported natively within Windows Server 2008 (or Windows 7), and therefore Dell has always seemed reluctant to fit USB3 hardware into its Servers. To make matters worse, most USB3 cards require some sort of SATA Power from the main board, and Dell does not provide these connectors inside the chassis either. So, …
