When designing a webpage, my computer used to freeze. When I checked the Task Manager, the CPU Usage reached to 100% wherein 98% is used by iexplorer.exe. I have been testing one of the webpage in Internet Explorer 6, 7 & 8 and each one of them made the CPU Usage reached to 100%. Using Firefox alone had no effect - meaning, it had its normal CPU Usage while testing the webpage.

I checked my CSS and tried to delete some of the codes until I finally saw this code which uses all of my CPU resources:

#content { height: expression(document.getElementById("content").offsetHeight); }

That is the code for IE6 to compensate its inability to interpret top:0; and bottom:0;

SCENARIO: A Vista server (Home Edition 32-bit), 3 XP clients and other 5 Vista clients joined together on a Workgroup. Twice a day, we have to restart the Vista server as the XP machine lost connection when trying to access a file from the Vista server and XP clients give the following errors:

• when opening My Network Places = Error: Workgroup is not accessible. You might not have permission to use this network resource. Network name is no longer available.
  
• when opening shared/mapped folder = Error: %Share% is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Access Denied.

First step to try:

- boot computer from Windows CD and choose repair (R)
- from command prompt run: chkdsk /r
- when checkdisk finishes, remove Windows CD and boot WindowsXP normally.

Second step to try:

- Follow procedures from Microsoft on how to recover from a corrupted registry that prevents Windows from starting  http://support.microsoft.com/default.aspx?scid=kb;en-us;Q307545

Third Step to Try:

- made sure ACPI, Plug & Play, USB all enabled in BIOS
- moved mouse from the ps/2 port to the first USB port
- booted using Safe Mode
- waited until it hung at Mup.sys
- removed the mouse cable from the USB port
- (3 seconds or so pass, the screen went black and safe mode appeared)
- restart the system
- boot normally into XP

We have HP Lasejet 4050n in our network, I re-installed the printer driver using its original which I guess a 10 year old driver, so no need for each workstation to connect to a Printer Server before printing. The goal is to print directly to HP Lasejet 4050 from the network.

After installing the driver to each computer, I found out that one of the PC couldn't print multiple page using Adobe Reader v9 (latest version at that time), but it can print using Adobe Acrobat 7, MS-Word & MS-Excel. I thought it is only because of the old driver. But I found out that changing the driver from PCL to PS solve the issue.

For any question, feel free to send me an email on forum(at)itropics.net and will try to answer your computer related queries.

Some hardware requires FTP, TFTP to upgrade the firmware like the Netcomm VoIP Gateway V431, V440, etc. When I was updating the firmware of my V440, I had no issue. But when I had to update my V431, the update doesn't want to move from 0% even though I checked that there is no firewall issue withmy PC and my router. So its best to make your PC as teh TFTP server, but of course you need the necessary firmware from the real FTP site and download it in your PC. We will be using C:\TFTP-Root as the location of our firmware files. Let's get started.

• Download Solawinds TFTP from this link http://www.solarwinds.com/register/registrationform.aspx?program=52&c=70150000000CcH2.You need to register to be able to proceed with the download. Add a comment

After repairing Windows XP or after replacing a motherboard, you might receive this error before logging in "This copy of windows must be activated with microsoft before you can log on."

• Download this patch which works for Windows XP Home and Prof.
• Reboot to Safe Mode.
• Open the downloaded file and double-click AntiWPA3.cmd
• Click Yes when it prompt.
• That should be it.
• Restart the computer and you should be able to login now.

You were login as a limited user and everytime you click Run LiveUpdate in Norton Internet Security 2009, it keeps saying that you need admin rights to run the update. But you don't want to give the user an admin rights.

The workaround is to

• open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\
• you will see InstalledApps & IntelligentUpdater from the left hand side
• right-click in each folder and select Permissions... then add the username of the one with limited account
• close Registry Editor
• login as the user with limited account, then try to click Run LiveUpdate and you should be able to update your Norton Internet Security.

I have Dell Inspiron and keeps receiving the Configuration Wizard everytime I open any office files and application (.doc, .xls., Outlook, etc.), then displays this error in Event Viewer.

Event ID: 1001 - Detection of product '{91120000-0014-0000-0000-0000000FF1CE}', feature 'WORDFiles' failed during request for component '{0638C49D-BB8B-4CD1-B191-051E8F325736}'

• I uninstalled MS Office Professional 2007, then reinstall it again using my CD. But I got the same error.
• I downloaded the MS Office Professional 2007 - Free Trial from http://us20.trymicrosoftoffice.com/product.aspx?sku=3203819&culture=en-US&banner=default Add a comment

After successful AVG installation on Dell laptops with Vista Home Premium:

avgfrw.exe - Application Error - The application failed to initialize properly (0xc0150004). Click OK to
terminate the application.

avgtray.exe - Application Error - The application failed to initialize properly (0xc0150004). Click OK to
terminate the application.

avgui.exe - Application Error - The application failed to initialize properly (0xc0150004). Click OK to
terminate the application.

The problem appears to be caused by a file being referenced in the registry that is not actually installed on the system.

1. Uninstall AVG if it is still installed, then restart the computer.
2. Use the registry editor (menu Start -> Run -> enter "regedit" and confirm OK) to locate and expand the following registry key:
'HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components\'

4. From the long list on the left, delete the following key:
'x86_microsoft.vc80.mfc_1fc8b3b9a1e18e3b_8.0.50727.762_none_0c178a139ee2a7ed'.

5. Restart the computer and reinstall AVG. Always use the latest AVG installer.

For the sake of XP installation continuity, we can use the default product key inside the XP CD.

You can find the product key by browsing:

<cd-rom drive letter>\i386\unattend.txt

At the bottom of the file, you will find the product key. One of the common product key is

CD87T-HFP4C-V7X7H-8VY68-W7D7M

After finishing the XP installation, you need to activate Windows and use the original product key of the computer.

I have Miscrosoft Office Standard 2007 where I installed to 3 Vista machines. The 2 machines were OK but the other machine keeps receiving a Configuration Wizard everytime he opens a doc & excel file. And I looked at the Event Viewer, I saw the warning "A provider, OffProv12, has been registered in the Windows Management Instrumentation namespace Root\MSAPPS12 to use the LocalSystem account. This account is privileged and the provider may cause a security violation if it does not correctly impersonate user requests."

I am not sure exactly what fixed the issue, I did not re-install Office 2007, what I did were the following:

1. Change the WMI -> Msapps12 & CIMV2 security by adding the local user account to have full access.
   To access your WMI, type wmimgmt.msc from Start Search. Once open right-click to WMI Control (Local) then select Properties.
   Right-click to CIMV2 & MSAPPS12 then click Security tab. Add the local user account (not the administrator) and designate it with full control.

You might recieve this error "Not enough server storage is available to process the command" while trying to access a shared folder from Vista (server) using your XP (client) computer especially after installing an anti-virus software (Norton Internet Security).

To fix it, you have to increase the IRPStackSize in the registry of the computer you've been trying to access, which in this case is the Vista PC.

In your Vista PC, open regedit from the command prompt, then dp the following:

1. Navigate to the following key:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
2. In the right pane, double-click the IRPStackSize value.
   
   NOTE: If the IRPStackSize value does not already exist, use the following procedure to create it:
   1. In the Parameters folder of the registry, right-click the right pane.
   2. Point to New, and then click DWord Value.
   3. Type IRPStackSize.
      
      IMPORTANT: Type "IRPStackSize" exactly as it is displayed because the value name is case-sensitive.
3. Change the Base to decimal.
4. In the Value Data box, type a value that is larger than the value that is listed.
   
   If you created the IRPStackSize value using the procedure described in step 2, the default value is 15. The computer automatically uses the default value of 0x0000000f (15), which we often find to be insufficient. It is recommended that you increase the value by 3, so try a decimal value of 18. The range is from 11 (0xb hexadecimal) through 50 (0x32 hexadecimal).
5. Close the Registry Editor.
6. Restart the computer.

You may try just to restart the Server service from "services.msc" rather not restarting the server, it may or may not work. It is recommended to restart the server after doing the above procedure.

There are times that accessing a shared folder or mapping a drive from Vista (as the server) using your XP (as the client) machine gave you this error "The specified server cannot perform the requested operation." Your only hope is restarting the server to allow access to the shared folder again.

To help you troubleshooting the issue, you may need to install LLTD (Link Layer Topology Discovery - KB922120) in your XP machine. Please check my other article for some helpful troubleshooting tips about Vista-XP sharing issues.

Download the WindowsXP-KB922120-v5-x86-ENU.exe, running it will give you an error not allowing you to install it, but there is a way around it...

1. Rename the WindowsXP-KB922120-v5-x86-ENU.exe to a simpler name e.g. 922120 and place it on e.g. C:\
2. Click Start button navigate to run prompt and type in cmd and press enter or click ok (a black window will open)
3. Type the following in the command prompt (cursor blinking)

The password which you have set in StoreGrid Web Console will be maintained in the StoreGrid internal database in an encrypted format. So it is not possible to decrypt the password by unforseen visitor.

If you feel the password which you are using currently is not that much secure, then we recommend changing it to an alternate (harder) password for your StoreGrid logon account. You can change the existing logon password for the StoreGrid webconsole by going through the menu "Administration -> Advanced Options -> User Management (tab)"  page in the StoreGrid webconsole. There you can configure the new password for your logon account under the tab 'Change Password'.

Please refer to the following URL to know more about 'Users Management'; http://www.vembu.com/storegrid/sp-help/PageHelp/user-administration.html

Open ports in your Amazon EC2 instance, port scans of Amazon EC2 instances are generally ineffective because, by default, all inbound ports on Amazon EC2 instances are closed, and are only opened by the customer.  The customer's strict management of security groups can further mitigate the threat of port scans. If the customer configures the security group to allow traffic from any source to a specific port, then that specific port will be vulnerable to a port scan.  AWS further encourages customers to apply additional per-instance filters with host-based firewalls such as IPtables or the Windows Firewall and IPsec. This can restrict both inbound and outbound traffic on each instance.

For further information on AWS Security, please refer http://awsmedia.s3.amazonaws.com/pdf/AWS_Security_Whitepaper.pdf

In StoreGrid Cloud AMIs, the Backup Server will receive the backup data from the clients and store the data in EBS volumes (as a temporary cache location) and upload the data to Amazon S3. Please note that, the EBS volume which we use as a temporary storage is also a persistent to store your backed up data.

Even, if the EC2 instance is stopped, the EBS volume will not be affected and the data will be intact with the EBS volume.

If your EC2 instance is stopped, you can create a new EC2 instance and attach the existing EBS volume to your EC2 instance . All your StoreGrid configurations and temporary cache data will be intact with the new EC2 instance. For redundant backups of the EBS you can also configure periodic snapshots for the EBS volumes by using StoreGrid. For that, you need to enable Snapshots in the SGConf.xml file present in the '<Mounted_Location>/SGCloudConf' location and specify the snapshot configuration in SGConf.xml file.

Please refer the following URL to get more details about configuring StoreGrid EC2 instance: http://www.vembu.com/storegrid/amazon-ec2-s3-cloud-online-backup.php

Does configuring Amazon S3 a pain for you? There is an easy way to backup in cloud using Jungle Disk for only US$2 per month. If you have Rackspace (also known as Mosso) account, don't worry as JungleDisk supports it as well.
