The data under "Documents and Settings" is the users profile. And
no, you can't have a user without a profile.
If you have not defined any profile for the user, they get a local
profile. This means that the profile is created the first time a
user logs on to the TS as a copy of the Default User profile. When
the user logs off from the TS, the profile is saved and stays on
the TS. Next logon, the profile is already there, so I don't think
that this could cause your server to slow down.
Disadvantages of local profiles are: users will have different
settings on different Terminal Servers + the C: drive of the TS can
easily fill up with the user profile data.
If you have defined a roaming profile for the users (on a network
share), then the centrally stored roaming profile is copied to the
TS when the user logs on (to "Documents and Settings"). When the
user logs off, changes made to the locally cached profile are saved
back to the centrally stored roaming profile. The advantage of this
is obvious when you have more than one Terminal Server: changes in
users settings will follow them from one TS to the next.
Copying of the profile could potentially slow down the logon and
logoff process, but you should always combine a roaming profile
with excluding some data from roaming with the profile (temporary
files, temporary Internet Explorer files, and so on). This is
actually the default. You should also delete the locally cached
copy of the roaming profile from the server when users log off, to
avoid filling up your C: drive.
Tell us a little bit more about the problem that you have with your
server:
* When exactly is it slow or even locking up?
* Does this only happen during logon and logoff, or also in the
middle of a session?
* When this happens, does it happen to all connected users
simultaneously, or only to some?
* When this happens, can you still logon to the console of the
server?
* Does the server recover itself after some time, or do you have to
reboot to get it responsive again?
* Is there anything in the EventLog on the server when this
happens?
* Have you checked in Task Manager if a process is using 100% of
the CPU when this happens?
