Outlook slow switching between folders
Problem:
A delay between switching folders in inbox, which is als present when switching back to inbox from other places such as Calander and Contacts. This can be fixed by disabling hardware accelleration.
Solution:
There may be a control for this in file/options/advanced under “Graphics” or “Display”. If not, you’ll have to edit the registry.
Step 1 – open your registry. Press the windows key and type “Regedit” then press enter or click the Regedit icon, windows 7 users you can type Regedit in your start bar.
Step 2 – Browse to: COMPUTER HKEY_CURRENT_USER Software Microsoft Office 15.0 Common Graphics. If you don not have a “Graphics” right click on “Common” and choose “New” then “Key” and create “Graphics” (no quotes)
Step 3 – Once on the Graphics “folder” right click it and choose new DWORD (32-bit) Value
Step 4 – Give the new DWORD a Value name: DisableHardwareAcceleration and give it a Value of 1 – Click OK to save it.
NO USB mouse or keyboard
Problem:
You start up and can’t log in or do anything. Many times customers will think thier PC has frozen, but in actuallity it’s just not loading the USB mouse and keyboard drivers on boot (finds new devices but fails the driver install). You can tell this if you see ascreen saver come on or new messages still popping up in the corner.
Solution:
If it’s not finding the driver, quick solution is to point the search to the WindowsInf folder (browse my computer for drivers). This should at least get you functionality.
Setup searches a predefined path on the drive, looking in .inf files to find the best match for the Plug and Play ID of the device. This path is defined in the following registry location and is set to %SystemRoot%Inf by default:
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionDevicePath: REG_EXPAND_SZ:%SystemRoot%Inf
Adding an entry with the actuall path may solve the problem her. Don’t delete the current path thoguh, add a ; and then type the path
; C:windowsinf
Modify the registry to deactivate Windows
Problem:
The windows activation windows keeps poping up even though windows says it’s been activated. This is frequently caused by someone using an activation crack, or by the wpa.dbl and wpa.bak files courrupting. Sometimes also happens after a repair installation of windows.
Before we can legitimatly (re)activate windows we first must de-activate it.
Solution:
In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
Expand SOFTWARE, and then expand Microsoft.
Expand Windows NT, and then expand CurrentVersion.
Under CurrentVersion, click WPAEvents.
In the right pane (topic area) of Registry Editor, right-click OOBETimer, and then click Modify.
Click to put the pointer in the Value data box. Then, modify any character that appears in the Value data box.
Click OK.
MTU Test
Problem:
How to check optimal WAN MTU settings.
Solution:
The primary reason is that in most if not all cases if you send packets at 1500 they will need to be fragmented resulting in degradation of performance. I would not reccomend changing the MTU settings without first checking the optimal settings for your environment, do not just take the word of your ISP, they are making a generalized statement that covers the masses, it is not a total optomization.
Checking is easy to do. First make sure that your MTU setting is in fact 1500 or the test is compromised and will result in a number that is too low.
The command is to see the largest packet is “ping -f -l XXXX www.XXX.com” -f -l forces the ping packet size to be what you specify, any size to lage returns a reply that the packet needed to be fragmented.
-l is a lowwercase L
XXXX is mtu speeds start at 1500 and decrease in multiples of 10 (1500, 1490, 1480 etc…) until you get a ping result, then increase in multiples of 1 until you again get the reply that the packets needed to be fragmented. The highest numbet that did not have to be fragmented is your highest optimal number. I would actually suggest decreasing it by 2. So if 1464 is the highest you could send without fragmentation set the MTU to 1462.
and XXX is a website of your choosing.
Laserjet p4015 constantly ramps up but dosen’t print
Problem:
When a print job is sent to the printer, the printer will display processing job on the control panel, and will continually ramp up and down attempting to print the job. After several minutes the printer will return to ready without posting any error messages. Occasionally, after several minutes the print job will print
Solution:
This usually isn’t a roller problem as the printer WILL pick up the paper, it just takes a few minuets, but it never hurts to check. Next check the firmware. If it’s older than 04.060.7, then it is causing a fault in the fuser. This is a documented problem and the fuser needs to be replaced. In addition, the firmware needs to be upgraded to version 04.060.7 or higher to prevent this error from recurring. You can download an executable firmware upgrade utility from :
Don’t forget to update the firmware to the latest version, if you haven’t already done it, to prevent the new fuser failing with the same fault.
