691 Error

The 691 error in Windows XP is a dial-up connection error. It appears when you try to establish a dial-up connection for your network so you can access the Internet. It is caused by your dial-up connection either being unsecured or unable to run correctly, and will prevent your computer from connecting to the Internet with the error as detailed below:

This is what the 691 error normally looks like:

“Error 691: The computer you are dialing in to cannot establish a Dial-Up Networking connection. Check your password, and then try again.”

and also:

“Error 691: Access was denied because the username and/or password was invalid on the domain.”

What Causes The 691 Error?

These types of error messages are caused when the following conditions are true:

• The Include Windows logon domain check box is selected in the Options tab of the dial-up connection’s Properties dialog box.

Step 2 – Clean Out The Registry With A Registry Cleaner

– Download this registry cleaner

The ‘registry’ is a central database which has been designed to help your computer run as smoothly as possible, as it stores a huge number of files & settings for Windows. This database is continually being used by all the applications on your computer to help your system run like it did when it was new.

The problem is that this database is often being used so much by your computer that it’s continually being saved in the wrong way. This not only causes the database to become damaged & corrupt, but it will also cause the likes of the 691 error, if Windows cannot read the files it requires to run. To fix this, you should look to use a ‘registry cleaner’ program, which should hopefully fix the error on your PC.
