Hi,
Both Tamj123 and Razz are correct; only some of these profiles may not show up since they are 'dead' profiles from previous installations.
The 'HTL-SERVER' tag is your server name. From the above, I can make out that it took you 5 installs to get it right :-)
Administrator.HTL-SERVER.nnnn are accounts created with the same name at each install. So to distinguich each account (instead of overwriting the old one, a new account with a numbered extension was created. This is because while doing a fresh install, you did not reformat the system partition (C drive by default).
The same happened during install - you propably changed the default windows directory. The default windows directory (for Win2K) is c:\winnt unless you change it to a different location.
Login as administrator (domain) and open a command window and type SET. Near the bottom of the screen (generally the last line) you'll see a line like this:
...
USERNAME=Administrator
USERPROFILE=C:\Documents and Settings\Administrator
windir=C:\WINDOWS
The last line tells you the active windows folder (in this case C:\WINDOWS. You could delete any folder named C:\WINNT or C:\WINDOWS001 etc. Just MAKE SURE that no programs refer to these folders anymore. You could also delete the Default User.xxx where xxx is not active.
Similarly, the second last line tells you where the active administrator profile is located. (REMEMBER, you will have one administrator account that was created before you ran Active Directory, DO NOT DELETE THAT ACCOUNT!!!) You can delete the other Administrator.HT....nnn folders that are not active.
My suggestion would be to do a clean install to get everything correct. Moreover, as you mention you need space on drive C, I would strongly recommend you to do so. This time allocate enough space for C.
:-)
Good Luck
