I have gone through several computers while at this job, and have transferred stuff from one machine to the next each time. Our MIS department allowed _me_ to log in when setting up initially most times, after which they took over and did their thing (although it's almost all automated now; we're at the cutting edge of the late 1980s). Sometimes I logged in as 'LongPhil', and sometimes as 'longphil'; depending on how _I_ logged in, the local profile was created with _that_ _name_ _and_ _case_. Forever afterwards, most, if not all, references to my account made by the system used the same case that I used. If your MIS guys don't allow U to log in to a new machine the first time, maybe they're using all uppercase characters when they log in using your account. The profile would then be 'DSMILEY', not 'dsmiley'.

username should be lower-case for $USER

The suggestion of just renaming your user account is actually the easiest one if you have administrative rights in your domain. But I do have a few other suggestions in case you don't. Since Windows is not a case-sensitive operating system and since the $USER environment variable is dynamically populated when you logon, try logging on with your user name as 'dsmiley' instead of 'DSMILEY' and see if that changes the environment variable. If it doesn't, you may be able to fix it by deleting your user profile and then logging on with your user name in lower case. As I said, Windows is not case-sensitive as far as user names go. You can log on as 'DSMILEY', 'dsmiley', or 'DsMiLEy' and it will work. But I don't know if it will change your $USER environment variable because I don't know exactly how Windows populates it. -Jason -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

If the user ID is created with lower-cased letters, it will be stored and reported in lower-cased letters. At least that is how the Windows 2003 Active Directory where I work expresses its user IDs. For example, our regular IDs are a number. Some special IDs have letters added to the beginning of the number. I am looking at user IDs right now through the AD User and Computers mmc snap-in and I can see that most of them are in all caps, but some are not. No matter how I look at the account name for this particular ID, it is in lower-cased letters. The reported 'dn' of objects with lower-cased letters have lower-cased letters in them, so AD will use that to report the values. I also know that when you initially log on to a system and it creates a new user profile for you, the folder it creates will have upper / lower -cased letters based on how you logged on and not on how AD says your ID should be capitalized.
