AIM Fix: “The AIM Service cannot be reached…”
This post was published 6 years 1 month 1 day ago which may make its actuality or expire date not be valid anymore. This site is not responsible for any misunderstanding.So what exactly is the annoying error that the AOL Instant Messaging Client gives us, in which is so gallantly titled: “The AIM Service cannot be reached…”. No duh?! How do I fix it!? Please note: This is an an older piece of writing of mine, and is a little out-dated, but very useful information.
The Sign-In Dialog Box

Put your Username in the ScreenName textbox and if you would like to type in your password in the Password dialog box. Next click the wrench-like icon, entitled Setup, to get to your screenname preferences.
Main Preferences Dialog

The Main Preferences Dialog Box is for settings for the current screenname. This is why we set your screenname before we went ahead into the Setup button. The Main Preferences Dialog Box is to change certain global settings to your screenname that you chose when clicking the Setup button. The main setting we want to change is the Sign In/Off settings. So click on the item in the left pane.
Next what we want to do is click on the Connection button in the lower right-hand area of the content pane. This will bring up the Connection Preferences for our AIM Client.
AIM Connection Preferences Dialog

This where we want to be: The AIM Connection Preferences Dialog Box. This allows up to re-configure the AIM Internet Connection settings that AIM uses to connect to their server. The Host and/or Port may have what is in the above graphic, or it might not. None-the-less, we need to re-configure the AIM settings.
So, the next thing we need to do is click the Auto-Configure… button so that we can re-configure the AIM Internet Connection settings. When you click on Auto-Configure… the following dialog box shows up:

You are going to want to click OK to confirm that you want AIM to reconfigure your internet connection for AIM only. Quickly you will see a few boxes flash before your eyes, and then you will come to this screen:

Congrats! This means you have successfully completed the AIM Internet Connection Re-Configuration settings!
AIM Sign-On Screen

Now, just follow your way out of the dialogs by pressing ok to the rest of the dialog boxes, until you come to the Sign-On Dialog Box. Now, you enter your screenname (this should already be in the textbox and insert your password for AIM. All you have left to do is click the Sign-On button and it should now work. Viola!
