 the sign-in method you're trying to use isn't allowed for more info, contact your network administrator

Solution (by : Altaf8Jun2010Dubai Airports):

start \run\gpedit.msc

goto computer configuration>windows settings>security settings>local policies>User rights management> Allow log on locally

here you will not be allowed to add any new users (may be only admins can do) but i added the troubling users into one of the group already available and that solved the problem.

Symptom: When trying to logon a computer using non administrator ID, you may receive this message: "You cannot log on because the logon method you are using is not allowed on this computer. Please see you network administrator for more details."
Case 1: Group Policy' "Allow log on locally" was not setup to allow users or domain users. To setup allow users or domain users to logon the computer or domain, you need to add the users or domain users to the "Allow log on locally". Please follow these steps to add the users.

1. Run gpedit.msc.
2. Expand Windows Settings\Security Settings\Local Policies
3. Click on User Rights Assignment
4. Ensure that "Allow log on locally" includes Administrators, Backup
Operators, Domain Users or Users.

Case 2: Group Policy' "Deny log on locally"  was setup to deny users or domain users. To setup allow users or domain users to logon the computer or domain locally, "Deny log on locally" should be empty or no users or domain users in the list. Please follow these steps to remove the users or domain users from the "Deny log on locally".

1. Run gpedit.msc.
2. Expand Windows Settings\Security Settings\Local Policies
3. Click on User Rights Assignment
4. Ensure that "Deny log on locally" is empty.

Case 3: The local group policy allow user to logon. However, domain group policy which overrides local policy doesn't allow users to logon locally. The resolution is modify the domain policy to allow users to logon locally.

Case 4:  The domain policy allows domain users to logon locally, but the local policy doesn't and the domain policy doesn't apply to the computer. The fix is running gpupdate to force to update the domain policy.
Case 5: Norton Firewall blocks the communication between the client and domain controller. The solution is disabling Norton firewall or re-configuring it to allow to access the domain controller.

   2. Type DefaultPassword as the value name, and then press ENTER.
   3. Double-click the newly created key, and then type your password in the Value Data box.
   Note: If the DefaultPassword registry entry does not exist, Windows XP automatically changes the value of the AutoAdminLogonregistry key from 1 (true) to 0 (false) to turn off the AutoAdminLogon feature after the computer is restarted.

因为个人用的电脑，每次都要输入用户名和密码是件麻烦事，所有有了下面的文章，大家可以参考下，第一种方法是xp,win2003都支持
继承了windows的一些的设置方法
第一种方法：也是比较简单常用的方法
运行里输入control userpasswords2 后确定，按照提示即可
这里介绍一下如何让Windows Vista启动时自动以某一用户名和密码登录系统的方法(此方法实际上也适用于Windows XP)。
1、win+r弹出运行。
2、输入“control userpasswords2”（防止输入错误，请直接复制），然后点击“确定”。提示：不需要输入引号，同时注意在control的后面有一个空格。
3、出现用户帐户控制提示时，点击“继续”。
4、在打开的用户帐户设置中，取消“要使用本机，用户必须输入用户名和密码”（图中已标注位置）设置前的勾，然后点击“确定”。
5、输入想要系统每次启动时自动登录进入的用户名和密码，然后“确定”。
6、重新启动，这样Vista即会以你指定的用户名登录了。
第二种方法：通过修改注册表
运行regedit打开注册表以后，展开[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon ]分支，然后在右侧窗口双击“DefaultUserName”，接着输入你的登录用户名。如果没有预设的用户名称，可以在注册表编辑器的菜单栏点选“编 辑→新建→字符串值(s)→DefaultUserName”来添加这个项目，注意要区分大小写字母。
同样在该分支下，在注册表编辑器的右侧窗口中双击“DefaultPassword”，然后在空白栏内输入你的密码。假如未发现“DefaultPassword”一项，可按上面的步骤来新建该字符串值。
接下来在右侧窗口中双击“AutoAdminLogon”，将数值设置为“1”。假如未发现“AutoAdminLogon”，可按上面的步骤来新建。
其它的方法也可以通过一些软件来实现，大家肯定感觉方法，第一种方法是最好用的。

如何让win XP实现自动登陆

http://www.aa25.cn/Tech/95.shtml

Windows XP是一个比较安全的操作系统，每次启动时都要求选择账户并输入密码，对于公用电脑，这样当然更安全，但是如果这台电脑是一个人用，也没有什么重要资料，每次都要选择帐户并输入密码实在太麻烦了，怎么样才能让 Windows XP 不用输入密码自动登录呢？

单击“开始/运行”，输入“rundll32 netplwiz.dll,UsersRunDll”，按回车键后弹出“用户帐户”窗口，看清楚，这可跟“控制面板”中打开的“用户账户”面板窗口不同哦！然后取消选定“要使用本机，用户必须输入用户名和密码”选项，单击确定，在弹出的对话框中输入你想让电脑每次自动登录的账户和密码即可。

事实上，在windows 2000中也可以这样实现自动登录，不过它可以通过“控制面板”打开“用户账户”窗口，而在Windows XP中不行罢了。
