Advanced/Computer Tech Level Support Below...
Note: Using the steps provided below can result in unfavorable results if performed carelessly, please do not attempt these until all other avenues are throughly investigated.

Note: Only use this next guide if you have exhausted the previous four actions:
Reset "hosts" file

The "hosts" file may be blocking the applications to access Internet:

Find your hosts file. The hosts file is normally found in the following locations:
Windows: C:\WINDOWS\SYSTEM32\DRIVERS\ETC.

1. Select the hosts file. Then click the Edit menu, and choose Copy.
2. Then, click the Edit menu again, and choose Paste. There should now be a duplicate of the hosts file named "Copy of hosts".
3. Drag the original hosts file to your desktop.
4. Drag the "hosts - Copy" file to your desktop. If Windows needs your permission to continue, click Continue.
5. Right-click the "hosts - Copy" file that is on the desktop, and choose Open. You may be prompted to choose the program you want to use to open this file. Double-click Notepad.
6. When Notepad opens, click the Edit menu, and choose Select All. Then click the Edit menu again, and choose Delete.
7. Click File menu, and choose Save. Close Notepad.
8. Drag the "hosts -Copy" file from your desktop back into the C:\Windows\system32\drivers\etc folder. If Windows needs your permission to continue, click Continue.
9. Right-click the "hosts - Copy" file you just moved, and choose Rename. Type "hosts" (without quotation marks) and press Enter.
10. Restart your computer and try connecting to the applications.


Note: Only use this next guide if you have exhausted the previous five actions:
Perform a clean boot

• Step 1
• a. Log on to the computer by using an account that has administrator rights.
• b. Click Start, type "msconfig.exe" in the Start Search box, and then press ENTER to start the System Configuration utility.
  If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
  
• c. On the General tab, click to select the option Selective startup, and then click to clear the option Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
  
• d. On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
  
  Note: Following this step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.
• e. Click OK, and then click Restart.

After the computer restarts...
1) Load d20Pro, enter as Judge, click on "Advanced" to ensure the port you are using is 10101, then click the green check mark to start your d20Pro server.
2) Goto http://www.canyouseeme.org
3) See if port 10101 is accessible from the internet

IF you get "Error: I could not see your service on ... on port (10101). Reason: Connection timed out." this means one of your Microsoft startup services is causing the issue. To fix this issue you must backup all data you want to keep, completely reformat your hard drive, reinstall windows and any programs you use, and restore your backup files.

IF you get "Success: I can see your service on ... on port (10101)" this means one of your non-Microsoft startup services is causing the issue. Lets find out which one...

• Step 2: Enable half of the services
• a. Follow steps 1a and 1b to start the System Configuration utility.
• b. Click the Services tab, and then click to select the Hide all Microsoft services check box.
• c. Click to select half of the check boxes in the Service list.
• d. Click OK, and then click Restart.

• Step 3: Determine whether the problem returns
• If the problem still occurs, repeat step 1 and step 2. In step 2, click to clear half of the check boxes that you originally selected in the Service list.
• If the problem does not occur, repeat step 1 and step 2. In step 2, select only half of the remaining check boxes that are cleared in the Service list. Repeat these steps until you have selected all the check boxes.
• If only one service is selected in the Service list, and you still experience the problem, the selected service causes the problem. Go to step 6. If no service causes this problem, go to step 4.

• Step 4: Enable half of the Startup items
• a. Perform a clean boot by repeating step 1.
• b. Click the Startup tab, and then click to select half of the check boxes in the Startup Item list.
• c. Click OK, and then click Restart.
• d. Repeat the d20Pro Judge steps and see if port 10101 is visible on http://www.canyouseeme.org .

• Step 5: Determine whether the problem returns
• If the problem still occurs, repeat step 1 and step 4. In step 4, click to clear half of the check boxes that you originally selected in the Startup Item list.
• If the problem does not occur, repeat step 1 and step 4. In step 4, select only half of the remaining check boxes that are cleared in the Startup Item list. Repeat these steps until you have selected all the check boxes.
• If only one startup item is selected in the Startup Item list, and you still experience the problem, the startup item that is selected in the list is the service that is causing the problem. Go to step 6.
• If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat step 1 and step 2 without selecting the Hide all Microsoft services check box in either step.

• Step 6: Resolve the problem
• After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved. Or, run the System Configuration utility, and then click to clear the check box for the problem item.

• Step 7: Reset the computer to start as usual
  After you have finished troubleshooting, follow these steps to reset the computer to start as usual:
• a. Click Start, type msconfig.exe in the Start Search box, and then press ENTER.
  If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
• b. On the General tab, click the Normal Startup option, and then click OK.
• c. When you are prompted to restart the computer, click Restart.

14 Jan 2011 : Update - Added Java to list of allowed programs, this was omitted earlier since I thought Java was always allowed. In addition, changed order of last computer-tech level order of operation since hosts file reset is much easier to complete than performing a clean boot.
