HP PSC 2410 Photosmart keeps clicking when turned on, won't print

An HP PSC 2410 photosmart all-in-one printer (thats the printer fax scanner copier model) won't print anything. When its first turned on you can hear a constant clicking sound. If you look closely at the scan head its lit up and moving slightly, almost like its jammed.

The problem was caused by dirty glass and the scan sensor not responding correctly. Dismantling the top of the scanner to clean it is straightforward - once you know the magical HP sequence to dismantle the top and take the 5 screws out.

You'll need a Torx T-10 screwdriver and to take a look at the photos in this HP document

Basically, unclip the scanner cover, undo the 3 screws, prise the control panel cover off from the front edge. Gently push the catch into the hole below the Black copy button. Slide the panel towards the front. You'll find 2 more screws under there that will release the glass. Clean the underside and re-assemble.

Unexpected shutdown after restart of SBS 2011 on Hyper-V with Remote Desktop

Got a client with Small Business Server (SBS) 2011 running on Hyper-V Server Core 2008 R2. I always remote in to load updates by using Remote Desktop (or Terminal Services client or Remote Desktop Services or Client or whatever its called this year)

I noticed this particular server always gives an Unexpected Shutdown after I click Restart once the updates are loaded. Also if I manually choose to Restart.

Couldn't see what was causing it until I came across this thread where a load of people with Blackberry Enterprise Server were having the same problem (this is a Dell Poweredge by coincidence too).

Scroll most of the way down for the post from JakesRNC. Its a quick and dirty fix but does the job. Putting 'net stop "Blackberry Controller" in the shutdown script for the server with Group Policy.

On the server,
Start > Run > gpedit.msc
Computer Config > Windows Settings > Scripts > Shutdown
Add a script with
   name = net
   parameters = stop "Blackberry Controller"

Symantec Mail Security ate all my disk space

An SBS 2008 server running on Hyper-V Core just ran out of disk space on the system volume. When I checked I found a 10GB Symantec Mail Security for Microsoft Exchange (SMSMSE or is that Information Foundation for blah blah) log file hiding in C:\Program Files (x86)\Symantec\SMSMSE\6.5\Server\logs.

I deleted it, but within a couple of minutes the free disk space had gone again. A scan of folder sizes using my old trusty dirsize.exe (and a second opinion from FolderSize) didn't show the culprit. The space had just disappeared. After rebooting the server and stopping the Mail Security services another log file appeared in the same directory.

Installed the latest version of SMSMSE (6.5.6.268) but it was still a problem. Turned out to be corrupt virus definitions and corrupt spam rules (Brightmail)

Shut down all three SMSMSE services,
delete the VirusDefs0000000x folders from C:\Program Files (x86)\Common Files\Symantec Shared\definitions\AntiVirus
and delete the following from C:\Program Files (x86)\Symantec\SMSMSE\6.5\Server
- bm_ruleset folders
- .sequence.0 and .sequence.2
- hashes
- blrm

Then run Liveupdate with certified definitions from SMSMSE Admin Status page
