How to troubleshoot user logon issues?

April 3, 2012 Leave a comment

User logon problems are sometimes hard to troubleshoot. Have you checked the Application log on the machine in question? There might be (most likely) some errors in there from source Userenv (ID’s 1053, 1054).
Turning on Userenv debug logging will also help in troubleshooting user logon problems. You can do this by adding a Registry key:

- Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
- Value: UserEnvDebugLevel
- Value Type: REG_DWORD
- Value Data: 10002 (Hex)

The log will be located in: %systemroot%\debug\usermode\userenv.log.

In the log you will exactly see what happens during logon at what time. If you see a large difference between times you’ll know what part of the logon process is causing the long delay.

A surrogate that focuses on Life Major Web traffic is called a “web proxy”. The most general use of a web surrogate is to perform as a web cache. Most delegate programs specify a means to forbid access to URLs specified in a blacklist, thus providing text filtering. This is over again adapted to in a corporate, pedagogical, or library circumstances, and anywhere else where content filtering is desired. Some trap proxies reformat web pages for a specific deliberateness or audience, such as to go to chamber phones and PDAs.Web Server is an medial server between patient petition and server resource
Content-filtering net surrogate
A content-filtering web substitute server provides administrative direction over the please that may be relayed sometimes non-standard due to the proxy. It is commonly employed in both commercial and non-commercial organizations  to secure that Internet form conforms to tolerable make use of policy. In some cases users can circumvent the delegate, since there are services designed to representative message from a filtered website through a non filtered locality to sanction it through the user’s proxy.

Some proverbial methods acclimated to inasmuch as essence filtering list: URL or DNS blacklists, URL regex filtering, MIME filtering, or peacefulness keyword filtering. Some products comprise been known to employ content dissection techniques to look in the direction of traits commonly old by standard types of content providers.

A content filtering substitute leave often bolstering user authentication, to supervision web access. It also usually produces logs, either to recite full information in all directions the URLs accessed past unequivocal users, or to prefect bandwidth usage statistics. It may also communicate to daemon-based and/or ICAP-based antivirus software to care for insurance against virus and other malware by scanning arriving purport in real hour in advance it enters the network.

Registry Keys Intended for Power Management

May 22, 2010 2 Comments

In this section, we’ll discuss the registry keys that are used for power management. You may edit any of them using one of the registry editors.

Note Changing registry entries responsible for power management won’t have an immediate effect. Windows only reads settings from the registry when you log on, when you click OK in Control Panel, or when a Powerprof.dll function is called on to read the registry.

The registry keys used for power management are listed below.

  • HKCU\AppEvents\EventLabels\LowBatteryAlarm – descriptive name of a low battery-power-alarm event
  • HKCU\AppEvents\EventLabels\CriticalBatteryAlarm – descriptive name of a critical battery-power-alarm event
  • HKCU\AppEvents\Schemes\Apps\PowerCfg\LowBatteryAlarm\.Current, HKCU\AppEvents\Schemes\Apps\PowerCfg\LowBatteryAlarm\.Default, HKCU\AppEvents\Schemes\Apps\PowerCfg\CriticalBatteryAlarm\.Current, HKCU\AppEvents\Schemes\Apps\PowerCfg\CriticalBatteryAlarm\.Default – filenames of the WAV files that will play as a low and critical power-alarm events
  • HKCU\Control Panel\PowerCfg\CurrentPowerPolicy – index of current user and machine power policy
  • HKCU\Control Panel\PowerCfg\GlobalPowerPolicy\Policies – the user global power policy (binary encoded data)
  • HKCU\Control Panel\PowerCfg\PowerPolicies\n\Name – name of power scheme n, where n = 0, 1, 2, etc.
  • HKCU\Control Panel\PowerCfg\PowerPolicies\n\Description – descriptive string for power scheme n, where n = 0, 1, 2, etc.
  • HKCU\Control Panel\PowerCfg\PowerPolicies\n\Policies – user power policy n, where n = 0, 1, 2, etc. (binary encoded data)
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\LastID – index of the last power policy in the lists of user and machine power policies (for example, if there are six user power policies and six machine power policies in the registry, the value of this key is 5)
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\DiskSpinDownMax – the maximum disk spin-down time that Control Panel will allow the user to set
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\DiskSpinDownMin – the minimum disk spin-down time that Control Panel will allow the user to set
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\GlobalPowerPolicy\Policies – the machine global power policy (binary encoded data)
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\n\Policies – machine power policy n, where n = 0, 1, 2, etc. (binary encoded data)

Power Schemes Configuration in Registry

May 22, 2010 Leave a comment


Power management configuration in Windows 2000, Windows XP, and Windows Server 2003 is based on the concept of power schemes. A power scheme is a group of preset power options that are passed to the Power Policy Manager component of the operating system to control the machine’s power-management behavior.

Each power scheme consists of a global power-policy structure and a power-policy structure.

  • Global power-policy structures contain preset power options that are global across all power schemes.
  • Non-global power-policy structures contain power options that are unique to a particular power scheme.

These power-policy structures are further divided into machine structures and user structures.

  • Values in machine structures are stored in the HKEY_LOCAL_MACHINE registry key, and none of these values are exposed in the user interface. For example, you can’t set any of these values using the Power Options applet in the Control Panel.
  • Values in user structures are stored in the HKEY_CURRENT_USER registry key and some of these values are displayed in the user interface. Some of these parameters can be set using the Power Options applet in Control Panel.

The data structures defining power management policy are listed below:

  • GLOBAL_POWER_POLICY – used to manage global power policies. This structure contains the data common to all power schemes. This structure is a container for a GLOBAL_USER_POWER_POLICY structure and a GLOBAL_MACHINE_POWER_POLICY structure, which contains elements that are read from and written to the registry.
  • GLOBAL_MACHINE_POWER_POLICY – this structure is a part of the GLOBAL_POWER_POLICY structure. It contains the data common to all power schemes and users. The elements in this structure are read from and written to the HKLM key in the registry.
  • GLOBAL_USER_POWER_POLICY – this structure is a part of the GLOBAL_POWER_POLICY structure. It contains the data common to all power schemes for the user. The elements in this structure are read from and written to the HKCU key in the registry.
  • POWER_POLICY – used to manage non-global power policies. This structure contains the data unique for all power schemes. This structure is a container for the USER_POWER_POLICY and MACHINE_POWER_POLICY structures that contain the elements to be read from and written to the registry. There is one POWER_POLICY structure for each power scheme on a machine.
  • MACHINE_POWER_POLICY – this structure is a part of the POWER_POLICY structure. It contains the data unique to each power scheme, but common to all users. The elements in this structure are read from and written to the HKLM key in the registry.
  • USER_POWER_POLICY – this structure is a part of the POWER_POLICY structure. It contains the data unique to each user and power scheme. The elements in this structure are read from and written to the HKCU key in the registry.

My Folder Settings in XP

October 13, 2009 1 Comment

Why Doesn’t Windows Remember My Folder View Settings?
If you’ve changed the view settings for a folder, but Windows “forgets” the settings when you open the folder again, or if Windows doesn’t seem to remember the size or position of your folder window when you reopen it, this could be caused by the default limitation on storing view settings data in the registry; by default Windows only remembers settings for a total of 200 local folders and 200 network folders.
To work around this problem, create a BagMRU Size DWORD value in both of the following registry keys, and then set the value data for both values to the number of folders that you want Windows to remember the settings for. For example, for Windows to remember the settings for 5000 local folders and 5000 network folders, set both values to 5000.
Here is how:
Follow these steps, and then quit Registry Editor:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type BagMRU Size, and then press ENTER.
5. On the Edit menu, click Modify.
6. Type 5000, and then click OK.
AND:
1. Locate and then click the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam
2. On the Edit menu, point to New, and then click DWORD Value.
3. Type BagMRU Size, and then press ENTER.
4. On the Edit menu, click Modify.
5. Type 5000, and then click OK.
Note:
When you use roaming user profiles, registry information is copied to a server when you log off and copied to your local computer when you log on. Therefore, you may have performance issues if you increase the BagMRU Size values for roaming user profiles.

Thumbnail Cache [Win Xp Tweak]

October 13, 2009 1 Comment

Thumbnail Cache

***************

[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced]

“DisableThumbnailCache”=dword:00000001

Windows XP has a neat feature for graphic and video files that creates a “thumbnail” of the image or first frame of the video and makes it into an oversized icon for the file. There are two ways that Explorer can do this, it can create them fresh each time you access the folder or it can load them from a thumbnail cache. The thumbnail caches on systems with a large number of image and video files can become staggeringly large. To disable the Thumbnail Cache, browse to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced and find the DWORD “DisableThumbnailCache”. You may need to create this key. A setting of 1 is recommended for systems where the number of graphic and video files is large, and a setting of 0 is recommended for systems not concerned about hard drive space, as loading the files from the cache is significantly quicker than creating them from scratch each time a folder is accessed.

Powertweak Application [Win XP]

Powertweak application

**********************

xxx.powertweak.com

Powertweak is an application, which acts much like a driver for our chipsets. It optimizes the communication between the chipset and the CPU, and unlocks several “hidden” features of the chipset that can increase the speed of the system. Specifically, it tweaks the internal registers of the chipset and processor that the BIOS does not for better communication performance between subsystems. Supported CPUs and chipsets can see a significant increase in I/O bandwidth, increasing the speed of the entire system. Currently the application supports most popular CPUs and chipsets, although you will need to check the website for your specific processor/chipset combo – the programmer is working on integrating even more chipsets and CPUs into the software.
