Troubleshooting Workgroup Connections

A common network configuration is a workgroup consisting of a few computers.  Each computer is connected to a router or hub, through an Ethernet cable or wirelessly, in order to share files or printers in a small office or home.  Problems connecting in this type of network can occur for many reasons.

Part of the troubleshooting process is to verify the computer name and the workgroup name.  The user could have changed the name of the workgroup or name of the computer in the Systems Properties dialog box, ran Network Connections Wizard, or Network Setup Wizard.

One way of checking the computer name, user nameworkstation domain, and other info is by using the command-line utility net config workstation.

Go to Start
Click Run
Type cmd to access the DOS command prompt
Type net config workstation
Press Enter

How I solved code 32 for Optiarc DVD RW AD-7580S

Crystal Clear device dvd unmountImage via Wikipedia

Yesterday morning my Lenovo laptop was unable to recognize a DVD in my Optiarc DVD RW AD7580S.  I hadn't used the DVD player for quite awhile and wondered when the problem actually began.

I proceeded to go into Device Manager to check the DVD/CD-ROM drives.  There was a yellow exclamation point over the DVD icon for the Optiarc DVD RW AD7580S ATA Device.  Since an exclamation point means there is some type of problem, I checked the Properties for the DVD player. An error code of 32 was generated in the Status text box on the General tab in the Device Manager Properties dialog box.

I linked to technet.microsoft.com to find out what Code 32 means.  Code 32: A driver (service) for this device has been disabled. An alternate driver may be providing this functionality.

Need an IP Address

You are having network connectivity issues.
  1. You have ruled out problems with physical connections such as your cables and network adapters.
  2. Your Windows Troubleshooter in the Windows Help and Support Center pointed to a TCP/IP address problem.  
Use the Ping command. TCP/IP  is a network protocol used in the Windows environment. TCP/IP automatically installs itself when it detects a network adapter. The Ping command allows you to check for connectivity between devices on your network.

You should Ping the loopback address first. The loopback address is 127.0.0.1. IP addresses that have 127 in the first octet are called loopback addresses. If this check fails, the TCP/IP configuration for your computer is incorrect. To ping the loopback address:

Losing your internet connection?

You are in the middle of something and you lose your internet connection. What a pain! 

You don't feel like calling the ISP and getting up to check your cable connections or resetting your cable modem. If your computer connects through a DHCP server, which chances are it does if you have a router, it means your IP address is automatically assigned by the server and can sometimes need to be renewed. 

You can do this by restarting your computer or if you want to save time there is an easier method. Try this: 
Go to START/RUN. Type CMD. 
Type ipconfig /release 
Press enter 
Type ipconfig /renew 
 Press enter.

Voila! Your internet connection is renewed.

Windows Vista Startup Repair Tool

System Restore // 18-8-2008
Image by twinkleboi via Flickr

Use the Startup Repair tool if your computer won't start up. Windows Vista has a Startup Repair tool that automatically fixes common problems. The Startup Repair tool scans your computer and attempts to fix it so your computer can start correctly. 

When your system detects a startup failure, it automatically fails over to the Startup Repair tool. The Startup Repair tool performs diagnostics to determine the cause of the failure, and then attempts to recover.

The Startup Repair tool can automatically repair incompatible drivers, missing and corrupted startup configuration settings, and corrupted metadata.  Afterwards, a log is provided to you about the steps that were taken in the repair, and diagnostic information to make further troubleshooting easier.

If the Startup Repair is unable to repair the startup errors, the system is rolled back to the last known working state.

If you want to start the Startup Repair manually, make sure the disc is enabled as a boot device in the BIOS with a higher priority than the other drives.  Insert the Windows Vista installation disc. Restart and follow these steps:

Hibernation power option

You need to configure your desktop computer to maximize the time between recharging your computer that is used infrequently during the day. What mode should you use?


Hibernation is a feature of laptops that allow them to enter into a low power state. This low power state will ensure that the laptop battery is not consumed when it is sitting idle. Hibernation can be configured through the Power Options applet in the Control Panel.

    Standby mode and Screen Savers

    You tried to configure your XP laptop to go into Standby after 15 minutes, but it is not working. What is wrong?

    Is a screen saver configured? If so, is it a Direct3D screen saver? Direct3D screen savers sometimes prevent a computer from entering standby mode. This is because a computer goes into standby only when the CPU has been idle for the time that is configured in Power Options. When a 3D screen saver runs, the CPU begins processing. This is a known issue in MS Windows XP and a hot fix is available.

    Autoruns -Another awesome freee utility from SysInternals!

    The sequence of components activated during th...Image via Wikipedia


    This week I received an email from my brother complaining about his Windows XP computer's slow start up time. He said the normal startup time was about 40 minutes! Ray said, "the computer runs fine once it starts, the problem is totally within the boot up process".

    Well, big sister to the rescue. Or, more like it, Sysinternals Autoruns to the rescue. My brother is in South Carolina, and since I am in Long Island, I used GoToAssist to do a remote dial-up session to his computer. After the session started, I quickly went to Live SysInternals to download Autoruns, written by the great Mark Russinovich and Bryce Cogswell, co-founders of Sysinternals, before it was acquired by Microsoft in 1996.

    With Autoruns, you can check to see what is actually running at startup on your Windows computer, and I mean everything that's running at startup. Autoruns shows you much more than the included Msconfig Windows utility. You will be surprised by the number of third party items loaded into your system at startup. The longer you have had the computer, the more 'stuff' will be configured into registries and directories and loading automatically when you boot up.

    Select the Options menu and click on Include Empty Locations, this will cause Autoruns to show all the locations it inspects. Under the Options menu, you also have the ability to hide Microsoft entries, a good thing to do so you won't deselect one of the needed system files by accident from your startup.  You should always combine the option to hide Microsoft entries with the option to Verify Image Signatures, to prevent hiding malicious programs.  Uncheck the unwanted third party items. If you are unsure about a particular item, Google it to see what it is.

    I went through the Autoruns and unchecked many, many boxes. After closing Autoruns, I proceeded to restart the computer. This disconnected my GoToAssist session, so I waited for Ray to tell me how fast the boot up was. Ray was ecstatic. He has never seen such a quick boot up on a Windows computer.

    I also have Autoruns loaded on my Windows Vista computer. My boot up is almost instantaneous, actually faster than my Macbook. And, I never thought I'd see that day. Thank you Mark Russinovich!  Windows is getting better and better!

    An easy way to increase Vista performance using ReadyBoost

    1 GB of SDRAM mounted in a personal computer. ...Image via Wikipedia
    Whenever we think about increasing our computer's performance, the first thing we think of is increasing RAM (memory). For the novice computer user, opening up the case and installing memory is out of the realm of consideration. An easy way to increase the memory is to use the ReadyBoost feature of Windows Vista.
    When you try to do things on your computer that don't have enough RAM, the system uses the paging file. The paging file is a small area on the hard disk that is used and is called virtual memory
    When information is swapped back and forth between physical and virtual memory, it is called paging. The more memory the system has, the less the system has to access the hard disk to retrieve data, and the faster the performance. However, more RAM is not always a good option. Your system might not have the capability to hold more RAM, not to mention the fact, that RAM is not cheap.

    Windows Meeting Space in Windows Vista

    Windows Vista Windows Meeting SpaceImage by CokeeOrg via Flickr
    Windows Meeting Space is a peer-to-peer collaboration program that allows you to share documents, programs, or your desktop with others.

    You can share your desktop or a program with other meeting participants.  You and the other meeting participants can share and co-edit documents.  One saved change is replicated immediately to every other meeting participant.  Any file or application can be broadcast or streamed, not just Microsoft applications. The administrator has the ability to limit the file types that can be shared.  The built-in logging feature can audit activity and write to the event log during a session.  You can pass notes among the participants.  You can connect to a network projector for a presentation.

    Windows Meeting Space automatically creates an ad hoc network, if it can't find an existing network. You can start a new meeting or join a meeting someone else has set up.  You can invite others on the network to join.  You have password protection and the session initiator decides who can join the session.

    Windows will automatically configure Windows Firewall the first time you start Windows Meeting Space.  You will be prompted to setup and enable People Near Me.

    BGinfo - One COOL Desktop background from Sysinternals!

    Technical Fellow Mark Russinovich talks about ...
    Image by Microsoft PDC via Flickr


    Imagine this scenario.  You have called tech support and the technician is asking you what version of Windows is on your desktop computer.  While troubleshooting, the technician asks how much memory is installed and how much hard drive space is available. 
    Imagine this scenario.  The IT department is installing new wireless network cards in all employee laptops.  You are a technician and you have been assigned the task of verifying the laptops that need new network adapters. 
    In either case, precious minutes are wasted scrolling though several diagnostic screens in control panel to get to the information, or you waste time asking the user questions they probably have no answer for.
    BGinfo is a really cool, free, Sysinternals utility written by Bryce Cogswell. BGinfo queries the Windows system and displays information on your desktop, such as ip address, computer name, memory, volumes and free space, Mac address, etc.  BGinfo writes a bitmap on your desktop and exits.  No system resources are consumed and it does not interfere with other programs.  You can put it in your start up folder so it displays current data every time you boot.   BGinfo is customizable and even lets you select the background color and wallpaper. Voila! You have the system info right at your fingertips. 
    Mark Russinovich, of Sysinternals, has written an article about BGinfo in windowsitpro magazine.  Go check Windows Sysinternals out, and while you are at it, check out some of the other free utilities these gods have written and check out some of Mark's Webcasts.  See my page autoruns-another-awesome-freee-utility.html referencing another one of my very FAVorite system utilities written by Mark Russinovich.

    Problems connecting to a host

    TCP/IP stack operating on two hosts connected ...Image via Wikipedia
    Users are reporting problems connecting to a host.  The firewall on the host is configured to block incoming ICMP packets.  The host is on the same IP subnet as your computer. 
    What tool can be used to test whether the host is connected to the network?
    You can use arping.  The arping command sends Address Resolution Protocol (ARP) packets to test connectivity.  But, since ARP is not a routable protocol, the computers must be located on the same subnet.
    What is arping?

    Unable to print to a network printer

    Cutaway drawing, illustration of an inkjet printerImage via Wikipedia
    Three users share a Windows XP desktop computer. An inkjet is connected locally to the desktop computer. The desktop computer also connects to several laser printers over the network.
    One of the users complains he cannot print to the local inkjet printer. Both of the other users are able to print to it.

    What should the user do?


    Answer: Install the printer while the user is logged in. When a printer is installed on a Windows XP computer that is in a workgroup or domain, the printer may need to be installed separately for each user.


    Install a printer on a home network
