Broken images on Outlook Web Access logon screen after Exchange Rollup installed

We don't normally use OWA but every so often a situation calls for it. Since our last Exchange 2007 Rollup Update, the OWA logon theme on our CAS host has been borked with broken images. It turns out that there's a known and long standing issue and a script which can be run manually to fix it. Best four seconds I spent today :)

HP LaserJet printers duplex when they aren't supposed to

Came across an issue today where, after a firmware update, a HP LaserJet P4015 decided to send paper from the Letterhead tray through the duplexer. I knew I had seen it before but couldn't recall how it was resolved, but eventually I stumbled across discussions of the same issue. Most refer to the use of an "All_ALM_types_OFF.prn" file which when sent through the printer resolved the issue. It turned out I had a copy of said file lurking in my "I must organise this one of these days" folder. Here's how the PRN file looks in Notepad++, since Notepad and web forums don't render the escape codes correctly:

However, this can also be dealt with from the printer's web console.

If you want to read about what Alternative Letterhead Mode does when it's on, try this HP page. If you want to know why, years after this issue was first flagged, HP are still shipping firmware which can trip this setting on various models then I have no wisdom for you :)

Find the Bluetooth MAC address on a Blackberry 7 device

This is a short one but apparently in the variety of awful Bluetooth support that car manufacturers provide, at least one requires the MAC address to be entered for successful connection. This is reasonably easy to find for wifi but you have to dig a bit for Bluetooth. Blackberry's convention appears to be that they are the same except for the last hex digit.

  • Click the Options icon.
  • Click Networks and Connections.
  • Click Bluetooth Connections.

The screen should now say:

            Bluetooth ON
            Discoverable NO
            Paired Devices

At this point, click the Menu button (to the left of the touchpad) and select Options. You will see:

            Device Name
            Allow Outgoing Calls
            Contacts Transfer
            LED Connection Indicator
            Encryption
            Connect On Power Up
            Device Address << this is what you’re looking for.

Hope this helps someone out there. I find helping people with car/BT issues frustrating as you can neither see the device or the car UI and are dependent on what you are being told is happening.
