What happens when Windows 8 or 8.1 shows the following arcane message whenever you try to connect to your wireless network: This connection has limited or no. ยท Greetings, We have several Windows 2012 R2 Remote Desktop Services Servers set up in our environment. I have an issue with only one of the RDS servers. Security Accounts Manager. Title: Security Accounts Manager | Author: clark@hushmail. Last updated: 3rd April 2. This article is based primarily on a local default setup of NT5. Professional or 2. K (Windows 2. 00. XP Professional and Server Editions. Much will apply across the NT range, but not all has been verified. Note that this is a partial update from the orginal version, there will be more additions, I just thought it was time to consolidate some stuff. This article has been written concisely and progressively, it is advisable not to skim read. Some stuff is advanced, use a test machine where possible. Special thanks to: (alphabetically ordered)esrever_otua: For pointing out something which I had missed about group memberships. For coding XORCheck.

Vladimir Katalov: For the PWSEx product key and working on the LM Hash Decoder V1/V2 projects. For inspiring a hash database space optimzation technique. Due to length and my decision not to divide this article into separate pages I have split the article into 4 main chapters. Users and Groups. Security Settings. Registry Structure. Passwords. Within these chapters are sections divided by a dotted horizontal line. To the left of this line is an image like so: These are anchors. If you right- click on them you can copy the shortcut/link address or left- click (IE only) and add it directly to your bookmarks. These bookmarks may change so I have used random hex as the link - make sure you name the link appropriatley. Users can be added via a MMC with the "Local Users and Groups" Snap- in being present (Windows includes two such MMCs; compmgmt. Add..] button in "Users and Passwords" - found in Control Panel. Active Directory is configured via the Active Directory Users and Computers Snap- in or dsa. Also via CMD: C: \> net user %username% /add. Another way that is usually forgotten is the Network Identification Wizard that shows up once when installing the 2. K operating system. On running it checks the current users, normally just Guest and Administrator and it also checks the Registered. Owner value located here: \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current. Version\ that was just entered earlier in the setup. If an account has not been created for the user listed, an administrative level one can be created here. Note you cannot overwrite passwords of existing accounts. To re- trigger this dialog, boot from Petter Nordahl- Hagen's boot disk: Load the SOFTWARE hive. Cd to \Microsoft\Windows NT\Current. Version\Ed Registered. Owner value; if an account is already created by that name or if a different one is required. Cd to \Winlogon\Nv 4 Run. Net. Access. Wizard. Ed Run. Net. Access. Wizard = 0x. 1On reboot keep the selection on Windows always assumes the following user has logged onto this computer: user name from dropdown list should be the Registered. Owner, enter a password, next, finish. The user will be automatically logged on. Remember to uncheck: Users must enter a user name and password to use this computer. In the Users and Password in Control Panel. Also remember that since this method uses the secure autologon feature any existing autologon credentials will be overwritten, this will probably not be a problem however. This method also works in XP, however the process is alittle more complex. If there are three or more Administrator/(power)users accounts collectivily present, users cannot be added via the re- triggered dialog, this is likely to be the case, hence you have to make it believe otherwise. If there are two or less, skip the SAM editing sections. Boot from Petter Nordahl- Hagen's boot disk: Load the SAM and SYSTEM hives. Cd to \SYSTEM\Setup\Ed Setup. Type = 0x. 2Ed Cmd.

Add a user (upto five can be added here, all at administratove level) and logon with that user name using a blank password. Run regedit. exe and write back the 0. C values. Amend the 0. C key, make a note of the new user number that has overwritten the orginal (F4,0. SID. Reboot to complete. Another unorthodox method is to run the net command as a service. Boot from Petter Nordahl- Hagen's boot disk and load the SYSTEM hive. Current. Control. Set. 00. 1\Services\ create a two keys for the two commands. The editor seems to have a slight bug in that keys cannot be created that are prefixed with an existing service name, eg: error on creating a key named foobar if a key named foo exists. Remember that the services will be processed in alphabetical order. Cd in the first alpha newly created key. Nv 4 Error. Control. Ed Error. Control = 0x. Nv 2 Image. Path. Ed Image.

Repeat the steps above, but with: Ed Image. Path = %systemroot%\system. Reboot and login, remove the keys. K creates a couple of system error event log so this may need removing. One method that is often mentioned, that does not seem to work (anymore(?)) is changing the default screensaver to a program that allows usermanagement like cmd. The settings are located here: regedit. HKEY_USERS\. DEFAULT\Control Panel\Desktop\explorer. DEFAULTSCRNSAVE. EXE=logon. This is the screensave that will be used if nobody logs on locally for awhile. Screen. Save. Active=1 - Active=1 Inactive=0. Screen. Save. Time. Out=6. 00 - Number of idle seconds before screensaver activation (5mins)Screen. Saver. Is. Secure=0 - This is the "On resume, password protect" option. Curious this option though, some kind of memory limit if set to 0. Important to note if more memory is used. However even if you update logon. SYSTEM user, which is who you will be while the "Winlogon generic control dialog" lurks in the background, does not have permission to add or modify any users - System error 5 has occured < br> Access is denied. If a user logs on, SYSTEM does have access, so some kind of security assumed before logon. It maybe possible using a custom program, certainly with access to regedit. The SID number is used in file, registry, service and users permissions. The machine SID is determined in hexidecimal form from here: regedit. HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\V (last 1.

SECURITYSometimes the SID number is referenced in decimal form: 2. E,4. 3,AC,4. 0,C0,8. D,0. 7,E5,3. B,2. B1) Divide the bytes into 3 sections: 2. E,4. 3,AC,4. 0 , C0,8. D , 0. 7,E5,3. B,2.
