Group names, user names and domains

[gururajan20815]

Hello,

I have a need to change all the user names and group names that have
spaces or upper case letters in our small domain. I need to change them
so that there only lower case letters and no spaces in any group name
or user name.

Am I correct in the idea that the SIDs are what are used for security
across the domain and changing the names will only have negligible
impact? It would only inconvenience those users that are using the
current user names? The group name changes would not affect anyone at
all???

Are there any "bugaboos" and "gotchas" that would require us to be
careful?

Would it be safe to do this on a production Primary Domain Controller?
Is it safe to do while the PDC is in operation?

Thanks,

Guru

for your users that will be changed from upper case to lower there
should be no issue since the username inputs are not case sensitive.
If the user account will be renamed (i.e. byoung renamed to bob.young)
I have seen issues with home folder rights and roaming profiles. As
for the groups I would only worry about any logon scripts that are
mapping based on the group name.

Good luck

Additionally I would say that it safe to pilot on some test accounts
within your production domain
