  • Long username and pre-windows 2000 logon

    I have a question about long usernames. Pre-Windows 2000 operative systems doesn't like usernames longer than 20 characters while Windows 2000+ accepts it.

    When I create a user in my Windows 2003 domain I get to name the account, I give it the username Username.Userlastname (which is 21 characters).

    Since the client OS is Windows XP and the Server OS is Windows Server 2003 I thought it would accept the long username, but it doesn't. The default way to logon seems to be prewindows 2000, with a drop down list to pick the domain. So to get the logon to work I have to enter the username [email protected], which makes the dropdown domain box grey and the logon attempt is accepted.

    Is there a way to make the client try to add the "@domain" to the end by default, so that my users can enter their long usernames without typing the domain at the end?

    I did use but there's a lot of crap out there and I couldn't quite find what I was looking for... any help or pointers, tips & tricks are welcome!

    Any advice I give is to the best of my knowledge, there is no guarantee what so ever that it will actually work in your particular scenario. I will not accept any responsibility for unexpected consequences, after all - you are taking advice from a complete stranger over the internet. =)

    I don't know of any way to automatically add the UPN suffix. But you can create another UPN suffix that's shorter if that's an issue.

    Sorry, it's not much help.

      Everything I'm reading says to avoid usernames with more than 20 characters. Not practical, I think, in your situation but that advice does crop up time and time again. Sorry I haven't got a better answer.
