How to Check the Hard Drive on a Mac

Computer hard drives don't normally fail without warning, unless you do something really dumb like I did one day. My daughter and I were on the LIRR going to NYC. She was eight years old at the time. Audra handed me her Macbook to carry....., as usual. As we arrived at Penn Station, I got up, my hands overflowing with everything else I was carrying, and I

Duplicate Contacts Calendars with MobileMe iPhone

I signed up for Mac MobileMe after it was first released and I am hooked. I love being able to sync  photos, contacts, and calendars in the cloud. Everything is automatically 'pushed' to your devices to keep your constantly changing information in sync. Add a new contact and there it is, already in sync on all of your Mac devices and in Outlook on your PC. I love not

Application Freeze on a Mac

You are pushed for time and are trying to get some work done, when your cursor turns into the spinning beach ball that you despise! You sit and wait precious seconds for the beach ball to go away. You move your cursor away from the application. The beach ball disappears, only to reappear when you move it back. Your computer is frozen. How can you

ZoomIT - SysInternals Zoom and Annotations Utility

Here I am again talking up the SysInternals utilities. ZoomIt is my newest obsession and I am on a roll. ZoomIt was written by Mark Russinovich, author of the SysInternals tools. Mark is now with Microsoft as a Technical Fellow. And, among his many accomplishments, he has just written a book called Zero Day, which I just finished reading and thoroughly enjoyed.

Trying to cleanup malware from your computer? Advanced Malware Cleaning, located on the Windows Sysinternals website, is a must watch video from Windows expert Mark Russinovich. Mark was the co-founder of Sysinternals before it was acquired by Microsoft in 2006.

Mark gives an overview of how SysInternals tools work, such as Process Explorer, along with using the AutoRuns utility,  SigCheck, and TCPView Utility to discover where malware is hiding on your computer and how to clean it. Mark talks about Rootkits and his own RootkitRevealer tool, an advanced rootkit detection utility.

Mark discusses the future of malware and how malware is becoming harder and harder to detect.

Iphone4 Crash

Tweet

Did you open an app on your iphone4 and the iphone suddenly crash or shut down? 

When you open an app on the iphone, it leaves the application open so you don't have to reopen it the next time you want to use it. This is a benefit of multitasking, one of the features of iOS4. 

If too many apps are open, your iphone could suddenly shut down. You might also notice your battery draining faster than it used to. The more apps open on your iphone, the faster the battery drains.

Windows Hang and Crash Dump Analysis Webcast Review

Recently, I spent an exciting Saturday watching and documenting a Sysinternal's webcast by Windows expert, Mark Russinovich, entitled, Windows Hang and Crash Dump Analysis. Mark takes you step by step into the internals of Windows to help you better understand how system crashes happen, what caused the crash, and how to fix it.


These are my notes I took during the Webcast. On a separate afternoon, while writing this blog, I tested WinDbg. Included in this documentation, are additional notes about what I did to create a crash dump, using the program Mark wrote called NotMyFault, and how I tested WinDbg. I am hoping the hours I spent watching and documenting the webcast will be useful one day to me and to my blog readers. The entire process has been a learning experience and very gratifying. 

And now, the Webcast....

Computer Lost Internet Connection

Most home computers connect to the Internet through a Dynamic Host Configuration Protocol (DHCP) server. This means the IP address is automatically assigned by the server (most likely your router).  IP addresses are automatically assigned (leased) for a time determined by your ISP.  The time varies, depending on the ISP.  When your lease expires you lose your internet connection.

Network Problems because your Wireless Switch is turned off

Image via Wikipedia

Many mobile laptops have a wireless switch on the front or side of the computer to enable or disable the wireless radio.  This functionality is usually added to allow laptop usage on an airplane or in other areas with radio sensitive environments.  You can switch off the wireless radio to enable usage of the laptop.  It could be an actual hardware switch or a led light by the keyboard triggered by a combination of keystrokes such as Fn, Ctrl, Alt in combination with function keys ranging from F1 to F12.  If you have a switch, make sure it is turned on in order to receive a wireless connection.

If you don't know how to turn on or off your laptop's wireless radio, consult the laptop manufacturer, or check the link below for a list of various laptop models and their corresponding wireless radio switches.

Problems with your DVD-ROM CD-ROM drives

You are having problems accessing your DVD-ROM and CD-ROM drives. The problem happened after you opened an email attachment. You need to make sure your drivers are the correct versions. However, you do not know how to do that. What should you do that will allow you to determine whether correct versions of the drivers are installed?

Run the DRIVERQUERY command-line tool.

• Open a command prompt window.
• Type driverquery /? (to get a list of the driverquery options)
• Type driverquery | more (to see a pageview display of drivers). note: the | sign on the keyboard is the broken line above the \

Driverquery is a quick way to generate a of list of installed drivers on your system.  However, in my opinion, a better way is to use DriverView, a free utility from NirSoft. DriverView works under all versions of Windows except for 98 and ME.

Wireless enabled and no internet connection

The following is a repost of an unusual problem encountered a few years ago while troubleshooting a friend's Windows Vista laptop:

I installed a free anti-virus software.  After the installation, I encountered one problem after another.  Windows Firewall connection turned off and became disabled.  I was unable to connect to the Internet even though my wireless connection was showing as enabled.  Internet Explorer was showing a "Page cannot be displayed" error.

I googled "wireless connection showing enabled and no Internet", as I had never before encountered that problem. A blog entitled, Repair and reset Windows Vista TCPIP Winsock Catalog Corruption popped up and described the situation. It was easy and solved the problem in five short steps.  Be sure to click on the link for an explanation as to what caused the Winsock corruption.  This fix could save you a lot of potential headache. Here is the Microsoft Knowledge Base article for  How to determine and to recover from Winsock2 corruption in Windows Server 2003, in Windows XP, and in Windows Vista.

Find IP address of Network Printer

Image via Wikipedia

If the printer has an Ethernet port, then it probably has a menu button to configure settings and you will have an option to display the IP address of the printer.

If there is a computer set up to use the printer:

1. Go to Start
2. Go to Control Panel (In Vista, type Printer in the search box on the Start menu)
3. Go to Printers and Faxes
4. Right click the printer
5. Click Properties
6. Click the Ports tab to display the IP address

You can ping your network from a computer connected to the network and look up an arp table:

1. Click Start
2. Click cmd
3. Type ipconfig to find your network address.  Most of the time it will be 192.168.1.1 (the default gateway) on a home network.
4. Ping your network using the broadcast address.  If your network address is 192.168.1.1, the broadcast address is 192.168.1.255 and you would ping 192.168.1.255.  If your network address is 192.168.2.1, the broadcast address is 192.168.2.255 and you would ping 192.168.2.255.
5. Then type arp -a to see the devices connected to the network.  One of the listed devices is the printer.
