Windows XP anonymous login

I'm trying to garner a feel for anonymous login implications with regards to Windows security. That said, consider the information per the link:

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/windows_security_differences.mspx?mfr=true

More specifically,

Windows allows anonymous users to perform certain activities, such as enumerating the names of domain accounts and network shares. This is convenient, for example, when an administrator wants to grant access to users in a trusted domain that does not maintain a reciprocal trust. By Default, the Everyone security identifier (SID) is removed from the token created for anonymous connections. Therefore, permissions granted to the Everyone group do not apply to anonymous users. If this option is set, anonymous users can only access those resources for which the anonymous user has been explicitly given permission.

Could I get a feel for what is meant by 'reciprocal trust'? Perused the web but I'm coming up short.

Thanks

Go to Windows Help, and type in GUEST account.

To turn the guest account on or off
A guest account provides access to the computer for any user who does not have a user account on the computer.

The steps to perform this task differ depending on whether your computer is a member of a network domain or is part of a workgroup (or is a stand-alone computer).

My computer is on a domain

You must be logged on as an administrator or a member of the Administrators group to activate or disable the guest account.

For information about activating or deactivating the guest account using Computer Management, click To disable or activate a user account.

My computer is not on a domain

You must have a computer administrator account on the computer to turn on and turn off the guest account on the computer.

Open User Accounts in Control Panel.
Click Guest.
Do one of the following:
To turn on the guest account, click Turn On the Guest Account.
The guest account will be activated. Now, a user without a user account on the computer can log on to the computer at the Welcome screen.

To turn off the guest account, click Turn off the guest account.
The guest account will be deactivated. Now, users without a user account on the computer will not be able to log on to the computer.

Notes

To open User Accounts, click Start, click Control Panel, and then double-click User Accounts.
Users who log on to the computer using the guest account do not have access to password-protected files, folders, and settings.

You lost me here. I'm not sure if I see the connection between 'reciprocal trust' (my original question) and GUEST account.

Reciprocal trust is when you enable writes and writes are enabled back for you.

An example of this would be adding a buddy to a messenger. He then sees a message saying you have added him and he can now add you.
