Windows XP Pro BSOD Event ID 7000 "Parallel Port Driver Service failed ..." [Solution]

Do you keep getting blue screen of death (BSOD) or sudden system power off with a restart? I had this recently when playing OMSI Bus Simulator but this can happen in other circumstances as well from the research I did on this. Either way this should help you fix this issue.

If you do check 'System' within your Event Viewer (Control Panel - Administrative Tools - Event Viewer). Look out for:

Event ID 7000, Source "Service control Manager", Description "The Parallel port driver service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

SOLUTION

Step 1) Boot into your motherboards BIOS and disable the parallel port (see your motherboards manual on how to do this).

If you don't know what make and model your motherboard is then use PC Wizard to find this out so you can download the manual from your motherboards manufactures web site (Google the manufacture if you don't know their web site address).

Step 2) Within Windows XP Professional open Device Manager (Start - Run, type in "devmgmt.msc" without the quotes and click ok).

Within Device Manager click on the 'View' menu and select 'Show hidden devices'. Scroll through device manager until you find 'Non-plug and Play Drivers - Parallel port driver', Right click and select 'Disable', click 'Yes' when presented with the stop functioning warning and restart when asked.

How to ping a specific port / How to test a connection between two computers on a WAN

With Windows XP it was possible to use the DirectX Diagnostic Tool, specifically Test DirectPlay to test a connection between two computers. It was mainly used as a gaming tool to establish which computer was blocking a connection.

However the best way to test specific ports is to use the telnet feature as you cannot "ping" a specific port. What telnet does is open a TCP connection on the port that you specify (if you don't specify one it defaults to 25). To do this is simple.

Firstly though if you are on Windows Vista / Windows 7 you need to enable the telnet feature (Windows XP users can skip this step). To do this; Click on Control Panel, click Programs, and then click Turn Windows features on or off. Scroll down to Telnet Client and tick the box. It will take several minutes to install.

Now open command prompt  (Win XP click on Run in start menu and type in "cmd" and press enter / Win Vista and; 7 users simply type "cmd" into your start menu's search box and press enter). Now use the telnet command in the same way as the ping command.

For example computer 1 has an IP of 127.5.45.55, and computer 2 (ip of 225.36.52.2) is trying to connect to port 6667 in order to play Generals but they cannot connect. Computer 1 would type into command prompt "telnet 225.36.52.2 6667". Computer 2 would type in "telnet 127.5.45.55 6667". As you can see it is extremely similar to the ping command. The results will be relayed back to the user.
