Audio not functioning




I have recently come across a large number of computers with a similar issue: No Sound from the speakers if a laptop or any of the jacks if desktop or laptopheadphones I have found a solution to this problem which has worked every time in my case. The instructions are as follows:

  1. Open an elevated command prompt by right clicking on the start menu entry and selecting "run as administrator".
  2. Type "net localgroup Administrators /add networkservice" and press enter
  3. Type "net localgroup Administrators /add localservice" and press enter
  4. Type "exit" and press enter to close the command prompt
  5. Now Restart the computer and you should have audio again.



How to perform an advanced restart in Windows 8

If you haven't noticed by now that windows 8 is considerably different than all previous Microsoft Operating Systems as such I have found that the f8 menu for advanced boot options has been eliminated and in order to achieve some of the functionality of the advanced boot options menu, you can boot to the login screen and click the power icon at the bottom right then hold shift and click restart, this will then present you with advanced restart options. These options include booting to the restore partition or selecting an alternate boot device.


VPN with RVS4000



I have been asked recently to provide VPN access for a small business, and decided to use the Cisco RVS4000 VPN Router as the device handling the vpn/client. The initial setup is similar to most routers i.e. enter your isp information (it is required to operate under a static ip using the router to handle authentication), configure your lan options (i would at this point recommend using an ip scheme other that the default 192.168.x.x as this can cause issues later). Once this is complete you can connect the rvs4000 to your modem and the local computers should now have network / internet access.

Now moving on to the VPN configuration on the router, at this point you will click on the VPN tab of the router interface and choose vpn client accounts. Once here you will have the option of creating up to 5 VPN user id's and passwords, you may also configure the option to let the user change his/her password (I recommend not). Type the user name and password you would like and select add/save. Now with the user account created, under certificate management click export for client, you will be prompted to save xxxx.pem do so to the desktop.



Now you have added your users and you can begin configuring the client software. Install the quickvpn client software and copy xxxx.pem to the installation directory i.e. c:\program files\cisco small business\quickvpn client\. This will allow the client to connect to the vpn. Launch quickvpn, give the profile a unique name, fill in the remaining fields and click connect. After a few moments you should be prompted showing you are now connected to the VPN.

Here is where things get sticky.

Now if you want that user to have access to folders on a workgroup share (not domain) you will have to go to the computer where the shares are configured and access the control panel \windows firewall \ advanced settings \ inbound rules, you will want to add 2 rules for ports tcp 433 and udp 500, then in the list you will see File and Printer Sharing (Echo Request - ICMPv4-In) double click on this and change the scope to any ip address. Click apply and your users will now be able to ping and browse network shares.

I hope this helped some of you out. Thanks for reading.


Prevent searching network places / network neighborhood

An issue I have come across recently was one in which a client did not want employees searching the contents of shared directories, however still wanted the ability to access the shares via the run command or address bar. In order to achieve this the only method I found was to disable the network neighborhood and remove the existing shortcuts in the directory "C:\documents and settings\%user%\nethood". In order to disable the network neighborhood discovery you must edit the following registry key.


Once in the above key you will add a DWORD titled "NoNetHood" and give it a value of "1".

This will prevent the Network Neighborhood from rediscovering the shares on the network and once you have deleted any entries in the folder mentioned earlier your search assistant will not search the network shares.

A common issue between Microsoft Windows and Norton Security products is that during updates to Norton products or the removal of Norton products is that the registry entries for the disk drives becomes corrupt. To resolve this issue you must open the registry by pressing the windows key on your keyboard and the letter R key together then type regedit into the run field and click "ok"

Once into the registry navigate to the following key:


Now in the right hand pane select the following:

Once you have deleted the above entries reboot the computer and your disc drive should be working.


Repairing BSOD error C0000135 The program cannot start because %hs is missing

This error is commonly found after removing a virus and can be very frustrating. In order to fix this issue you must first follow the instructions found in the post "Edit the registry of a windows 7 computer that won't boot" and you will select the "System" Hive. Once in the loaded hive you navigate to the following:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\SubSystems
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Session Manager\SubSystems

The value for the key windows will be this:

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=consrv:ConServerDllInitialization,2 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

and should be changed to this:

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

The value of consrv was created by the virus, and once you removed the virus infected .DLL the system was not able to load causing the C0000135 %hs blue screen of death.


Outlook .pst errors

If you are having problems launching outlook or if you receive an error regarding errors in your .pst (personal file folder) you can try to run ScanPST.exe and fix problems.

The program itself can be found in one of the following locations

  • local disk:\Program Files\Microsoft Office\OFFICE12
  • local disk:\Program Files\Common Files\System\Mapi\1033\
  • local disk:\Program Files\Common Files\System\Mapi\1033\NT
  • local disk:\Program Files\Common Files\System\MSMAPI\1033
  • local disk:\Program Files(x86)\Microsoft Office\Office12
  • local disk:\Program Files(x86)\Common Files\System\Mapi\1033\
  • local disk:\Program Files(x86)\Common Files\System\MSMAPI\1033

Once opened you can browse to your .pst file which is generally located in the following folder

  • local disk:\Documents and Settings\%user%\local settings\application data\microsoft\outlook            for XP
  • local disk:\Users\%user%\appdata\local\microsoft\outlook         for Vista/7

You then click repair and ScanPST.exe will begin a series of checks on your file. Once that is complete ScanPST.exe will ask if you want to create a backup of your file before you proceed with any repairs, give this a relavent file name and choose repair.


Categroy 5e pin-out Diagram











These are the standard pin outs for creating a category 5e (cat 5e) ethernet cable for use with wired 10/100/1000 networks.

*Unless you need to create a "cross-over" cable you would use the same standard A or B for both ends. Using A on one end and B on the other end is for creating a "cross-over" cable.

If you are having a problem with an error stating "not enough server storage is available to process the command." you may have a value in the registry for irpstacksize that is too low here are the instructions on how to resolve this:

  1. Click Start and select Run
  2. Type regedit
  3. Expand the HKLM key to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
  4. Select the DWORD Value IRPStackSize and choose edit
  5. Input a Decimal Value between 15 and 48 (48 being more)

A Description of IRPStackSize from Microsoft:

The IRPStackSize parameter specifies the number of stack locations in I/O request packets (IRPs) that are used by Windows 2000 Server, by Windows Server 2003, and by Windows XP. You may have to increase this number for certain transports, for media access control (MAC) drivers, or for file system drivers. Each stack uses 36 bytes of memory for each receive buffer.





How to reset your windows 7 product key and re-activate

I have recently come across a situation in which a computer would not allow me to use the traditional methods of activating windows 7. Here is a method which worked for me.

1. Open an elevated command prompt. (click the start menu, click all programs, click accessories, right click command prompt and choose run as administrator.)

2. Now in the command prompt type: slmgr.vbs -ipk (your product key). *note do not include the parenthesis but do include the dashes in your key.

3. You will see a prompt stating your product key has been successfully changed.

4. In the command prompt type: slmgr.vbs -ato which will initialize the windows activation.

5. Once the activation is complete you will see a prompt notifying you whether this process was successful or encountered a problem.

If successful your product should now be activated and the little prompt at the bottom right will go away after a reboot.
