Won't recognise some hyphenated user names

[laserblazer]

I've just set up new user names in AD and had three that cannot logon, all with hyphenated names but others with hyphens are accepted. I've got around it by shortening their names but wonder why it should be. I don't think it's a length thing.

I had the same problem before and was fixed by shortening the names (user/computer).

I usually worked with the one next to 0 and not on the num pad.

Are they using the keypad "-" symbol rather than the one next to the zero? I know it sounds odd but I seem to recall having a similar problem in the past which was due to this.

Just tried a couple and it seems the keypad - is not accepted. Thanks

The keypad one is a minus not a hyphen so it obviously knows the difference!
Thanks for the useful info

I don't allow hyphenated surnames on our network anymore, it was mainly due to the fact we had a student with a hyphenated surname, both of which were "foreign" (I'm not going to name them). Imagine Johnnie Van Der Valke - Von Hindenburgh, and then count the letters involved .. his username was over 20 characters (it also caused issues with SIMS).

I was also amused by the girl who had a double barrelled forename AND a double barrelled surname. I usually drop everything after the hyphen, it makes life a lot easier. I still remember one student who tried to spell Xavier with a Z, it's his own name, how can he not spell it.. How stupid can these people get , and try to make stuff easy for them.

I work with Artsaudi and we dropped ALL forms of hyphenation ( - ' ) and spaces. It was particularly confusing with Arabic names that in one family have a hyphen for one child's last name, but not for the sibling!! By eliminating it all together, it is easier on both the user and network admin.
