Hi,

Can anyone help me in increasing the length on username in windows server 2008 R2 ?

I can create more than 20 letters, but when I try to access the shared files on the server, it asks me for the login details. I enter the username I've created, but it is not accepting, but one I deleted some and make it 20 letters, it get access without even changing the username on the server !

Hope that you've got the point..

Regards,

It sounds like you are talking about the "pre-Windows login" name of the user, also called the sAMAccountName attribute of the user in Active Directory. This has been limited to 20 characters since Windows 2000, and the limit has remained for backward compatibility.

If you created the user in ADUC with more than 20 characters, you were assigning a value to the "Name" of the user, which is the Common Name (the value of the cn attribute). This value can be up to 64 characters. As you key this value into the new user interface in ADUC, the first 20 characters are entered in the field labeled "pre-Windows 2000 logon name", which is the name the user can logon with.

Edit: I should add that the 20 character limit is enforced by the system, the Directory Service itself, and not the schema. This cannot be ch

Thank you so much Richard for you reply.

Yes, exactly I'm talking about the "pre-Windows login" So we to shorten the name of the long staff !? Is that okay with windows server ?! since I don't have Windows 2000 in my environment. Can't I remove that !?

Once again thanks ..
