Powerful power supplies

I was building a new PC for a client. The thought came across, how powerful should it be? Here is some interesting info I have found.

A PSU will ONLY use from the source what is being?drawn by the system load.

A PSU that runs warm/hot draws?more power.

Therefore: It is?for more?economical to run a higher watt PSU than a lower watt an the system components will always run cooler when there is a PSU installed that is well overrated for the system.

The more efficient your PSU, the less noise it will make, the less power it will draw, and the less it will cost. PSUs are rated at five levels ? 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold and 80 Plus Platinum, with Platinum being most efficient. If you use your PC a lot you will want to go with at least a Gold rating.

Stop Cryptolocker

Stop Cryptolocker, or at least get warned if it starts encrypting files on your file server. The link below has instructions on how to setup File Server Resource Manager in Windows Server. By adding in certain file extensions you will be able to setup automatic emailing (and shutdown if you want) to detect when Cryptolocker starts encrypting files on your file server. There are also many other great tips on how to protect your server.

Outlook 2010 safe mode dodgy patch

Microsoft’s patch tuesday 8/12/15 brought update KB3114409.

The patch was meant to fix issues with Outlook 2010 however it breaks Outlook and forces it into running in Safe mode and also prevents the preview pane from working unless you manually turn it on.

The fix is to uninstall the patch. Go into Programs & Features, View installed updates and search for the kb number. Double click it to uninstall.

Microsoft have pulled the update.

Upgrading Cisco Switch Firmware Slow

I recently upgraded a Cisco 3560X switch. I upgraded from 12.2(53)SE2 to 15.0(2)SE8. I thought this would take 5 minutes max. After ten minutes I was worried. I connected a console cable and found the console reporting “Front-end Microcode IMG MGR: Programming device 0…rrrrrrwsssssssssssssssssssssspssssssssssssssssssssspsssssssss”

After googling I have discovered it is quite normal to take up to 40 minutes due to an upgrade to the MCU (Micro Processing Unit). This happens when updating to a higher version with newer microcode.

PHEW! It was a heart stopping 40 minutes.

 

Virtualbox resize problems

I had an issue with resizing a Virtualbox .vdi file.

Command used:

vboxmanage modify disk.vdi –resize 40960

Error displayed:

VBoxManage: error: Cannot register the hard disk ‘disk.vdi’ {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} because a hard disk ‘disk.vdi’ with UUID {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} already exists

Solution: 

vboxmanage modifyhd {abc03a41-794b-4a84-adaf-789436919417} --resize 40960    (e.g 40gb hd)

replace {abc etc with the correct UUID

 

See the link below for more detail and the solution.

Office 365 Experience w/ changing primary domain and sync.

Scenario: Needed to change the primary domain name of a user from one domain to another.
The user also wanted to continue using OneDrive for Business Sync Client (for Windows).

Experience: Changed the users primary domain name in the 365 portal. Re-setup Outlook profile and also the users iPhone.

Regarding OneDrive for Business, once the primary domain was changed the OneDrive for Business URL did not update straight away. This took roughly 4-6 hours to update. Once the URL updated, all of the data was automatically moved to the new URL path. I then had to stop syncing the old path and resync the new URL path in the sync tool. This of course meant downloading all of the data. I figured this would be quicker then trying to wipe out the data in the cloud and re-uploading all of the data.

20,000 sync file limit?: Later my client discovered he could not sync more then 20,000 files with the windows sync client. This is an actual limitation with the sync client. I have discovered Microsoft are working on releasing an updated version of the sync client later this year. The sync client will also support large files up to 10GB, and allow selective folder sync. There is likely a preview version out at the moment.

Update to El Capitan: Updated from Yosemite to El Capitan. The OneDrive for Business sync client (preview) does not work at all. Office 2016 is also randomly crashing.
