Logon failure: the user has not been granted the requested logon type at this computer

1. Access this computer from the network

This user right determines which users and groups are allowed to connect to the computer over the network. Terminal Services are not affected by this user right.

Default on workstations and servers:
Administrators
Backup Operators
Users
Everyone


2. Deny access to this computer from the network

This security setting determines which users are prevented from accessing a computer over the network. This policy setting supersedes the Access this computer from the network policy setting if a user account is subject to both policies.


3. Network access: Sharing and security model for local accounts

This security setting determines how network logons using local accounts are authenticated. If this setting is set to Classic, network logons that use local account credentials authenticate by using those credentials. The Classic model allows fine control over access to resources. By using the Classic model, you can grant different types of access to different users for the same resource.
If this setting is set to Guest only, network logons that use local accounts are automatically mapped to the Guest account. By using the Guest model, you can have all users treated equally. All users authenticate as Guest, and they all receive the same level of access to a given resource, which can be either Read-only or Modify.

Default on domain computers: Classic.
Default on stand-alone computers: Guest only

Important

With the Guest only model, any user who can access your computer over the network (including anonymous Internet users) can access your shared resources. You must use the Windows Firewall or other similar device to protect your computer from unauthorized access. Similarly, with the Classic model, local accounts must be password protected; otherwise, those user accounts can be used by anyone to access shared system resources.

Note:

This setting does not affect interactive logons that are performed remotely by using such services as Telnet or Terminal Services
This policy will have no impact on computers running Windows 2000.
When the computer is not joined to a domain, this setting also modifies the Sharing and Security tabs in the Windows Explorer to correspond to the sharing and security model that is being used.

I normally add a standard Admin Install user that has been given permission to add Computers to the Domain to the Workstations and make sure that Remote Access is enabled.
Log on with an account that has Domain Administrator priveleges on the PC that you want to add the account to.

Right click on My Computer and select Manage.
Navigate to Local users and Groups and open Groups.
Double left click on Administrator and select Add.
Type in the User Account name and select Check Names.
The name should appear.
Click OK. Click Apply and OK again.

You should now be able to access that Workstation with that account.

I still can not access sharing folder

by vanbinh.nguyen In reply to Check these settings

My friends, I had checked all setting that you determined. But i still can not change the situation. If i remove everyone group from "Access this computer from the networ" --> run GPUPDATE -> add Everyone group to "Access this computer from the networ" again -> run GPUPDATE . I can access sharing folder one time. I can not access again after disconnected.
It probably by virus. But we avoid to install antivirus softwares because of other programs(production programs).
Please help me if you know anything?(my computer is not joined domain, just LAN)

Try this

Follow the steps below with the System started and restarted in Safe Mode with Networking. Running in Safe Mode loads a minimal set of drivers for the Operating System. You can use these options to start Windows so that you can modify the registry or load or remove drivers. If you can access the Internet use it to download and install the files.

If you can't access the internet to update MBAM try the instructions below to clear a path to the internet to be able to run MBAM. You can also download the updates for MBAM and run them from the USB.

From another System download and install Spybot, update it and copy the the installed folders to a USB Stick. Copy MBAM and the Update as well.

With the new strains of Virus that have been created you may find it necessary to rename the executable files so that they will work. Rename mbam-setup.exe and then navigate to the install folder and rename mbam.exe. Do not change the files extension from .exe. Do the same with Spybot.

Removing malware from System Restore points:

When your infected with any trojans, spyware, malware, they could have been saved in System Restore and can re-infect you. It's best to remove them.

XP
Press the WinKey + r type sysdm.cpl and press Enter.
Select the System Restore tab and check "Turn off System Restore".


Vista
Press the WinKey + r type sysdm.cpl and press Enter
Select the System Protection tab. Untick the box next to Local Disk C: and any other drives and click on Turn System Restore off.


After scanning the system and removing the offending malware, re-enable System Restore by repeating the steps, this time removing the check from "Turn off System Restore".
When all is clear you may need to tidy up the Registry. Link is at the bottom.


Once you have restarted the Infected System in Safe Mode, navigate to the USB stick and run Spybot.

Download Spybot - Search & Destroy and install it. Update it. http://www.safer-networking.org/en/download/index.html

When you first start Spybot, click on the Mode menu and select Advanced mode. Under the Tools options (bottom left) select View Report. On the screen in the right hand pane, select View report to create a new report. Save the report as it may come in handy later. Spybot will also keep log files in this location in Vista:

C:\ProgramData\Spybot - Search & Destroy\Logs

Spybot will also keep saved log files in this location in XP:

C:\Documents and Settings\All Users\Application Data\Spybot - Search & Destroy\Logs


Download Malwarebytes Anti-Malware, install it and update it.

<a href="http://download.bleepingcomputer.com/malwarebytes/mbam-setup.exe" target="_blank"><u>Malwarebytes</u></a>

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Quick Scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.

If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
<a href="http://malwarebytes.gt500.org/" target="_blank"><u>mbam-rules</u></a>

I would keep scanning with it until it is clean by closing out and rebooting and running it again.

Those applications should be able to get you up and running. Here are some extra tasks if it is not working for you.

Tip! If you want to write protect the USB drive/stick while you are working on an infected System.
In the recent release of Windows XP Service Pack 2 (SP2), a new feature was added by Microsoft to allow the write protection of USB block storage devices. This entails a simple Registry modification that requires no hardware devices to write protect thumb drives.

If the USB drive has no small switch for write protection you can turn it on through the Registry via Command Line.

REG ADD HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /v WriteProtect /t REG_DWORD /d 1 /f

and one to turn it off but a System restart is required. Place a Batch file on the USB to turn it off.

reg delete HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /f


If TaskManager has been disabled this will enable TaskManager to allow access to the Registry.

Command line removal or create Batch files.

Click Start Run and type cmd and then press Enter.

Execute the following commands in the command line in order to activate the registry editor and Task Manager:

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /f

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /f

You could also check these registry entries and change the values from 1 to 0 if they are disabled.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center "FirewallOverride" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center "AntiVirusOverride" = "1"


If you are still having problems try this.

Download Combofix and rename the executable Combofix.exe to cfix.exe before running it.

http://www.combofix.org/

By now you should know what the name if the infection is, if you think that it may have infected the MBR try this.

Fixmbr - Repair Master Boot Record and remove Viral activity: XP Win2003

Site
http://www.ambience.sk/fdisk-master-boot-record-windows-linux-lilo-fixmbr.php

Download
http://www.ambience.sk/experiments/MbrFix.exe


Download MbrFix to c

Press Winkey + r and type in cmd and press Enter.

now type cd\ and press Enter.

now type MbrFix /drive 0 savembr Backup_MBR_0.bin and press Enter.


now type MbrFix /drive 0 fixmbr /yes and press Enter.

now type exit and press Enter.

Restart the System for it to take effect.


Registry Cleanup:

Download and install CCleaner to tidy up your Registry. Backup the Registry as you go along, rescan again and again saving as you go until there are no errors left.

Cleaner: Windows

When you first open Ccleaner you will have an option to Analyze or Run Cleaner, after checking the left Pane and making your choices. Delete all Temp Files. If you scroll down you will see a greyed out box that has Advanced next to it. Left click on it and keep pressing OK to all of the responses. I normally Untick Windows Log Files and Memory Dumps as they may come in handy.

You don't have to install all of the add ons or shortcuts just the one to the Desktop.
