[more=readme]WHAT IS UPHCLEAN
================
UPHClean is a service that once and for all gets rid of problems with user
profile not unloading.
You are having profile unload problems if you experience slow logoff (with
Saving Settings for most of the time while logging off), roaming profiles
that do not reconcile, or the registry size limit is reached.
WHY DO PROFILES NOT UNLOAD?
===========================
Many system and service processes do work on behalf of users. When the work
is done the system or service process is responsible for releasing handles it
has to the user profile hive. If this is not done by the service as the user
logs off the profile cannot be unloaded.
This problem in code can be caused by improper coding either in Microsoft
software or 3rd party software (e.g. printer drivers, virus scanner service,
etc). With the information provided by the system there is no way to find
out what software needs to be corrected to allow profiles to unload.
This problem can be caused for a variety of reasons. While software developers
are typically very careful about releasing handles, developing software that
works on behalf of a logged on user is complicated. It is difficult for
software developer to have full control over how the registry is accessed.
Service developers might want to see KB article 199190 for more information.
While it is possible to identify the service (see KB article 221833), it is
sometimes difficult to track this down the specific problem code. Even when
you do identify the problem code there maybe times when the developer of this
code is not able to make the necessary changes. This is the reason for
UPHClean -- it takes care of the problem regardless of the reason why.
WHAT DOES THE USER SEE? WHAT HAPPENS TO THE PROFILE?
=====================================================
Windows NT4:
The system gives up immediately on failure to unload the profile
and the (roaming) profile is not reconciled.
Windows 2000:
The system attempts to unload the profile 60 times at 1 second intervals.
This retry logic rarely helps so in most cases after 60 seconds of the user
waiting at the Saving Settings message box the system gives up and roaming
profiles are not reconciled. The number of retries can be changed to allow the
user to log off faster (this can be done using the policy under Computer
Configuration, Administrative Template, System, User Profiles, Maximum retries
to unload and update user profile)
Windows XP and 2003:
The profile is reconciled using a copy of the contents of the registry. The
user is not made to wait as in Windows 2000. The problem left is that the
computer cannot recover the memory the profile uses until it can be unloaded.
Also in some cases (e.g. using anonymous logons) you may find that you cannot
log on if the profile cannot be unloaded.
WHY SHOULD I USE UPHCLEAN?
==========================
The concept of UPHClean is to deal with these the same way the operating
system deals with other resource issues: when a task is done resources
(memory, handles, etc) are automatically reclaimed. UPHClean accomplishes
this simply by monitoring for users to log off and verifying that unused
resources are reclaimed. If they are not it reclaims the resource and logs
its action. This approach is superior as it works for any known reason
that profiles do not unload and also will keep working to address new
unknown issues.
Another advantage to UPHClean is that no computer restart is required to
install it or remove it (except on Windows NT 4). You can install and
remove UPHClean to find out whether it helps with a profile unload problem or
not. You can do this without having to worry about what hotfix, service pack,
feature pack, etc has been installed. Set it and forget is the goal of
UPHClean.
By default UPHClean takes action to allow profiles to unload. You can
choose to have UPHClean only report what processes it finds preventing profiles
from unloading. To do this, install UPHClean and use the registry editor to
set:
HKLM\System\CurrentControlSet\Services\UPHClean\Parameters\REPORT_ONLY to 1.
You can also have UPHClean log the call stack that is responsible for the
profile hive handle. This is necessary to find out what software is
responsible for the hive handle in processes used for many purposes (e.g.
svchost.exe, dllhost.exe, winmgmt.exe). To enable call stack logging use the
registry editor to set:
HKLM\System\CurrentControlSet\Services\UPHClean\Parameters\CALLSTACK_LOG to 1.
Logging the call stack is computationally and memory intensive. You should use
this option to collect information and then turn it off. To get more accurate
call stack logging it may be necessary to get symbols installed on the
computer. You can read about getting symbols at:
http://www.microsoft.com/whdc/ddk/debugging/symbols.mspx HOW CAN I TELL IF I'M HAVING A PROFILE UNLOAD PROBLEM?
======================================================
Events are recorded in the event log in most cases. You can use Event Viewer
to look for the following events:
Windows NT 4:
The application event log has error events with source Userenv, event id
1000. The event text is:
The operating system was unable to load your profile. Please contact
your Network Administrator.
This is the only symptom you find in the event log of a Windows NT 4 computer
indicating this problem is present. The only way to be sure is to use UPHClean
to find out if you have this problem or have some other problem.
Windows 2000:
The application event log has error events with source Userenv, event id
1000. When you call up the event you get the one of following events:
Windows cannot unload your registry file. If you have a roaming profile,
your settings are not replicated. Contact your administrator.
DETAIL - Access is denied.
- or -
Windows cannot unload your registry class file. If you have a roaming
profile, your settings are not replicated. Contact your administrator.
DETAIL Access is denied.
- or -
Windows cannot log you on because the profile cannot be loaded. Contact
your network administrator.
This last error is relevant if you find one of the other ones earlier
in the application log.
Windows XP and 2003:
You will see of the following error events in the application log:
Userenv/1517:
Windows saved user X registry while an application or service was still
using the registry during log off. The memory used by the user's registry
has not been freed. The registry will be unloaded when it is no longer in use.
This is often caused by services running as a user account, try configuring the
services to run in either the LocalService or NetworkService account.
Userenv/1524:
Windows cannot unload your classes registry file - it is still in use by other
applications or services. The file will be unloaded when it is no longer in use.
Userenv/1500:
Windows cannot log you on because your profile cannot be loaded. Check that you
are connected to the network, or that your network is functioning correctly. If
this problem persists, contact your network administrator.
This last error (1500) is relevant if you find one of the other ones earlier in
the application log.
INSTALLATION
============
To automatically install it (you need uphclean-setup.msi):
- Double click the setup.msi
To manually install it (you need a copy of uphclean.exe):
- Create a directory under Program Files for the service
(e.g. c:\program files\uphclean)
- Copy the program (uphclean.exe) to the directory
(e.g. c:\program files\uphclean\uphclean.exe)
- Open a command prompt on the computer
- Change directory where you copied the program
(e.g cd \program files\uphclean)
- Run the program with the -install switch to install the service and start it
(e.g. uphclean -install)
The service is set to automatically start when the computer boots so you will
not need to start it manually. Below I've listed the events that you will find
in the application log when it takes positive steps to unload profile hives.
INSTALLATION PROBLEMS
=====================
If you get an error using the MSI installation package and the package is on a
network share attempt the installation from a local drive. Another alternative
is to use the manual installation instructions.
If you have problems with the installation check to see if the following DLLs
are in your c:\winnt\system32 directory:
msvcp60.dll
msvcrt.dll
These files are commonly on computers because of other installed software.
If you are missing these files you can visit:
http://support.microsoft.com/default.aspx?scid=259403 to download vcredist.exe which includes these files.
On Windows NT4 you will need to restart the computer. On restart UPHClean will
start automatically.
UPGRADING
=========
If you used the manual installation method to install UPHClean you must follow
the manual removal instructions before attempting to use the MSI package to
install. You can find out if you used the MSI package by looking for an entry
for User Profile Hive Cleanup Service in Add/Remove Programs under Control Panel.
If you used the MSI package to install then you can proceed with the new package
without removal.
REMOVAL
=======
If you used automatic installation:
- Open Control Panel
- Open Add/Remove Programs
- Click on User Profile Hive Service and select Remove
If you manually installed:
- Run the program with the -remove switch to stop the service and remove it
(e.g. uphclean -remove)
- Remove the UPHClean directory under c:\program files
PROBLEMS USING UPHCLEAN
=======================
Because UPHClean assists in unloading the users registry hive some services
may behave incorrectly. Administrators are encouraged to test and watch for
unexpected behavior. If unwanted behavior is identified contact the
developers of software that UPHClean identified as preventing profile from
unloading.
UPHClean assists the operating system to unload user profile hive by
remapping the handles to the user profile hive to the default user hive.
For example if a process has a handle to
HKEY_USERS\S-1-5-21-X-Y-Z\Software\Microsoft after remapping it would have a
handle to HKEY_USERS\.DEFAULT\Software\Microsoft. This allows the profile
hive to unload. This may not work if the application expects data
that would only be available under the specific user profile hive it was
accessing since the data will not be copied.
If you find that removing UPHClean stops a particular problem from occurring
then you may be interested in restricting UPHClean from processing certain
handles. UPHClean ignores handles that are held opened to profile hives for
the users specified on the user exclusion list or by processes specified on the
process exclusion list. These lists are specified using the following
registry values:
HKLM\System\CurrentControlSet\Services\UPHClean\Parameters\PROCESS_EXCLUSION_LIST
HKLM\System\CurrentControlSet\Services\UPHClean\Parameters\USER_EXCLUSION_LIST
Note that since these values are specified as REG_MULTI_SZ strings you should
use regedt32 on Windows NT and Windows 2000 to edit them.
The process exclusion list is a list of process names that UPHClean should
ignore when determining which handles to user profile hives to act on. Each
process name is specified on its own line when input in registry editor. The
process name should be specified the same way as it shows in Task Manager.
Usually this is the file name of the program (e.g. notepad.exe).
A few process show multiple times in Task Manager. It is possible to specify
that a certain DLL be loaded in the process to allow a selection of a specific
process. This is useful with the svchost process to identify a specific
instance. For example to specify the svchost process that the Remote Procedure
Call (RPC) service is running in on Windows 2000, Windows XP and Windows Server
2003 you would specify svchost.exe/rpcss.dll in the process exclusion list.
The user exclusion list is a list of user security identifier (SID) or user
that UPHClean should ignore when determining which handle to user profile hives
to act on. Each user SID or name is specified on its own line when input in
registry editor. If specifying a user name you must enter the user domain name
followed by a backslash followed by the user name. For example
RCARONDOM\RCARON to specify the user RCARON from domain RCARONDOM. SIDs should
be specified in the usual string format (e.g.
S-1-5-21-2127521184-1604012920-1887927527-68486). This is the same string you
see under HKEY_USERS in registry editor.
Note that the user exclusion list always includes the following SIDs: S-1-5-18,
S-1-5-19, S-1-5-20. Unloading these profiles can cause problems so UPHClean
will not attempt to process handles to these profiles.
Which processes UPHClean performs handle remapping can specified using the
following registry value:
HKLM\System\CurrentControlSet\Services\UPHClean\Parameters\REMAP_HANDLE_PROCESS_LIST
The list by default contains '*' which specifies that handle remapping should
be performed for all non-excluded processes. This list can be changed to only
include specified processes in the same manner as the process exclusion list.
Processes specified on this list can be preceeded by a '-' character to specify
that they should be excluded from handle remapping. Any handle for a process
that is not excluded but has handle remapping turned off will be closed.

5) Here the service is telling you that the user profile hive could not be
unloaded and that it will try again later. I expect that this will occur
if the 1211 event occurred. As I don't expect 1211 to occur I'd expect that
event id 1111 will not occur either.

6) If you are using the reporting only mode (see above on how to set) you will
get event id 1501 whenever UPHClean detects a user logging off and the profile

get event id 1511 whenever UPHClean detects a hive loaded for an extended
period of time if the user is not logged on (whether there are handles
to it or not). This is important because it is possible that terminal
server could run out of kernel mode resource (paged pool memory) when that
happens. This could lead to users being prevented from logging on.
