W2k Pro not saving Registry changes?!

[dannydanny]

Hi,

We are all using W2k Pro SP3, and are in an AD domain.
Recently I migrated all our computers from an NT4 domain into the AD one.

Before migration, usre only had to type their password when loggin on as the username field was filled already with the previous logon username.
After migration, upon logging into their computers, some users have to type their username and password all the time, whereas other only have to type the password, with the username already filled in from the last logon.

All my users just want to type the password, so I made a registry change to the Local Machine hive using regedt32. There is key software\Microsoft\Windows\CurrentVersion\policies\system\dontdisplaylastusername.

I set this key to 0, then re-boot. Upon logging in again, the user name does appear as wanted, so the user only has to type the password, but the next day, the username field is blank and I have to go into the registry to change the key again.

What could make the registry "reset" itself? Is it a group policy? But half of our other users don`t have this problem......

Any ideas much appreciated,
Danny

I forgot to add that I`m making the registry changes under the local Admin account.

We have the same setup but in our case it is a group policy that overwrites the local policy. So when users here try to make the same change it won't stay after they reboot their system. For security reasons we don't want to make it easy for anyone to logon as someone else.
