I have a user with a typo'd name. For the sake of explanation, I'll say the username is lusername, first name Lindsay. Active Directory had the user initially named Lindsey Username, and I need it to be Lindsay Username. As you can tell this doesn't affect the actual login name of lusername.
If I go into Active Directory Users and Computers and search for lus, her name comes up.
I open the properties, and I can change the first name and display name fields, but I can't change the initial name at the top of the "general" tab.
Is there a way to "fix" this without resorting to recreating the user?
Right click the user, select Rename.
First it will allow you to change the name of the user, then it will pop up a dialog box allowing you to change the Full Name, First Name, Last Name and Display Name fields.
