Terminal Server and connected Terminal Services clients pause when a
Terminal Services client logs on or logs off
http://support.microsoft.com/default.aspx?scid=kb;en-us;324446
This article was previously published under Q324446
SYMPTOMS
When a Terminal Services client logs on or logs off (either in a session or
on the console of the Terminal server), the Windows 2000-based Terminal
server together with the connected Terminal Services client computers may
stop responding or may pause for several seconds. Users may also experience
one or more of the follow symptoms:
When a user types in a document, characters do not appear on the screen
until this pause has ended.
Keyboard input and mouse input are queued, but they are not processed until
this pause has ended.
Live performance monitoring (Perfmon) graphs have missing data points during
this pause.
All running programs appear to stop responding, or"hang," during this pause.
When Spooler is under a load from a large number of users, a high CPU usage
is displayed for it.
CAUSE
This problem may occur if there is a contention among server resources. The
contention causes a delay in processing that appears as a pause or as
unresponsiveness.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products
that are listed in the"Applies to" section.
MORE INFORMATION
To install the hotfix that is described in this article, the Terminal server
must be running Windows 2000 Service Pack 3 (SP3) or later. This fix is also
scheduled to be included in Windows 2000 Service Pack 5 (SP5). After you
install the hotfix and restart the computer, you must turn on the Power
Protect write cache option for each hard disk that has write caching enabled
and that has its write cache protected against accidental loss of power. To
configure the Power Protect option, use the Dskcache.exe tool.
For additional information about how to obtain the Dskcache.exe tool and how
to use it to configure the Power Protect write cache option, click the
following article number to view the article in the Microsoft Knowledge
Base:
811392 Obtain the Dskcache.exe tool to configure the"Power Protected" write
cache option
When you run Dskcache.exe without any parameters, the current write cache
settings for all hard disks are displayed. For each hard disk that is
currently installed on your computer, the following information is
displayed:
Disk device :
\\?\\ <SCSI DEVICE ID>
Current Settings :
Write Cache is [ enabled | disabled ]
Power Protect is [ enabled | disabled ]
To turn on the Power Protect option on a hard disk, use the p command-line
switch.
For example, to turn on the Power Protect option on drive C, type the
following line at the command prompt, and then press ENTER:
dskcache +p c:
The following information is displayed for drive C:
Disk device :
\\?\\ <SCSI DEVICE ID >
Current Settings :
Write Cache is enabled
Power Protect is disabled
New Settings :
Write Cache is enabled
Power Protect is enabled
Note You can turn on the Power Protect write cache option only for disks
that are currently present on your computer. By default, the Power Protect
option is turned off. As a result, this option is turned off for any hard
disks that are added to the computer after you apply this setting. When you
add additional hard disks, you must turn on the Power Protect option for
those disks if you want the setting to apply to those disks.
You must also configure the following registry subkeys on the Terminal
server and on all file servers:
In the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Lanmanserver\Parameters
subkey, configure the following entries:
Name: MaxWorkItems
Data Type: REG_DWORD
Value data: 12000 (decimal)
Name: MaxMpxCt
Data Type: REG_DWORD
Value data: 2048 (decimal)
Name: MaxRawWorkItems
Data Type: REG_DWORD
Value data: 512 (decimal)
Name: MaxFreeConnections
Data Type: REG_DWORD
Value data: 100 (decimal)
Name: MinFreeConnections
Data Type: REG_DWORD
Value data: 32 (decimal)
In the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Lanmanworkstation\Param
eters subkey, configure the following entry:
Name: MaxCmds
Data Type: REG_DWORD
Value data: 2048 (decimal)
By default, your registry does not have a Configuration Manager subkey. To
create the key, locate and then right-click the following subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager
Point to New, and then click Key. Type Configuration Manager, and then press
ENTER.
In the new HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session
Manager\Configuration Manager subkey, configure the following entry:
Name: RegistryLazyFlushInterval
Data Type: REG_DWORD
Value data: 60 (decimal)
