First reboot once your PC and if that does not work then:
when you login with your local admin account are you able to ping the DC? Also, check the IP settings to make sure they are correct. Are you using DHCP or are you static? If you are able to ping the DC adn IP settings are correct, is the computer name in Active directory? Also if the computer name is in active directory, is it disabled? If you check all these things and you are still having issues, drop the computer from the domain, rename it and create the new name in Active Directory and then add the computer back to the Domain. Somewhere along the line of following these steps, you should get the computer back inline. If other computers are able to connect to the domain then it is definitly an issue with this computer name or a setting on this computer.

Thanks

Reset Password Windows Server 2008, 2008R2


As the popular use of Windows Server 2008, large amount of trivial things come up with us each minute, the occasion that we reset password Windows Server 2008 becomes also common. Therefore, Windows Server 2008 password reset is the necessary technique for us now!


Windows Server 2008 is one of Microsoft Windows Server serials of operating systems. Besides Windows 7, Windows Server 2008 is the latest and more secured versions from Microsoft. Windows Server 2008 has newly added many new functional features included that system administrators of small and large companies will enjoy.


Most of us use Windows 2008 Server as a workstation. That means a group of computers and devices on a network that are controlled as a unit with common rules and procedures. And the host manages these computers through its admin account and password.


If you forgot windows server 2008 password of local admin, I think it is easy for you to recover the password. But what if you forgot windows domain password? Things will get trickier and all of the computers in the domain paralyze. These passwords also called AD password. Before solving your password problem, you need to know what Active Directory Domain Controller is.


What is Active Directory Domain Controller?
A domain controller is a server that is running a version of the Windows Server operating system and has Active Directory Domain Services installed.


When you install Windows Server on a computer, you can choose to configure a specific server role for that computer. When you want to create a new forest, a new domain, or an additional domain controller in an existing domain, you configure the server with the role of domain controller by installing Active Directory Domain Controller(AD DC).


There are differences between Domain and local. A Windows Server domain is a logical group of computers running versions of the Microsoft Windows operating system that share a central directory database. A user may be granted access to a number of computer resources with the use of a single username and password combination.


A Domain Controller allows password authentication throughout a network. What this means is that your password is checked on the central server no matter which machine you log in from. A Domain Controller can also control access to files and directories which can be setup so users have access to all their files no matter which machine they log in from. This also makes adding and removing users among other things much easier as all that is required is a change on the Domain Controller itself rather than every machine on a network.


If you need reset domain administrator password (also called AD password), it will be a tricky thing. However, Ainorsoft Windows Password Recovery can allow you to reset password Windows Server 2008 domain.


Steps for Windows Server 2008 password reset domain:
Step1. Google Windows Password Recovery Corporation, download and install in any available computer.
Step2. Create a bootable CD/DVD or USB flash drive. (A blank CD/DVD/USB Flash Drive is needed)
Step3. BIOS set. Boot computer from the created CD/DVD/USB Flash Drive and set BIOS setup.
Step4. Reset Windows server 2008 or 2008R2 password to Re123456.

How to Reset AD Password for Windows Server 2000, 2003 and 2008?


Have you ever forgotten Active Directory (AD) password? Do you know how to reset AD password? Is there any Windows password reset software to do AD password reset? If not, what to do to reset AD password? Before answering these questions and do AD password reset, you need to what is active directory, Windows domain and domain controller.
What is Active Directory?Active Directory is used by system administrators to store information about users, assign security policies, and deploy software. It was released first with Windows 2000 Server edition and refined further in Windows Server 2008 and Windows Server 2008 R2 and was renamed Active Directory Domain Services. AD components include such domains, domain controllers, trust relationships, forests, organizational units, etc. What is a domain controller?
According to Wiki, a domain controller is a server that responds to security authentication requests (logging in, checking permissions, etc.) within the Windows Server domain. The domain controllers in your network are the centerpiece of your Active Directory service. It stores user account information, authenticates users and enforces security policy for a Windows domain. When you install Windows Server on a computer, you can choose to configure a specific server role for that computer. When you want to create a new domain, or an additional domain controller in an existing domain, you configure the server with the role of domain controller by installing AD DS.
What is a Domain?A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
The domain concept not only allows a user to have access to resources that may be on different servers, but it also allows one domain to be given access to another domain in a trust relationship. In this arrangement, the user need only log in to the first domain to also have access to the second domain's resources as well.
So it is hard to say if there any windows password recovery software can reset AD password. Windows password recovery software like Windows Password Unlocker Enterprise can allow you to reset domain administrator password on Active directory for Windows server 2000/2003/2008.
Steps to reset domain administrator password
  • Step 1: Download and install Windows Password Unlocker Enterprise in any available computer.
  • Step 2: Run the software and insert a USB flash drive to computer.
  • Step 3: Select Domain Administrator and target USB drive, and then click the Burn button to start burning an ISO image file to the USB flash drive.
  • Step 4: Click ok when burning process is completed.
  • Step 5: Insert the burned USB flash drive to your locked computer and set the computer to boot from USB.
  • Step 6: Choose the way to reset AD password.
  • 2 options for you to reset domain password
  • 0b60bd0.jpg
  • Option 1: Reset the default domain administrator password to Pa123456
  • Option 2: Reset AD password by creating a specified domain administrator account.
  • Step 7: Click YES to continue and click Ok when the domain password has been successfully reset.
Now you can log on your domain with the user name of administrator and password of 'Pa123456' if you select option 1. If you select option 2, you can log on domain with the username of 'passkiller' and password of 'Pa123456'.

All the email in opera dissapeared and i can retrieve it


the issue might be a server connection error ..just use another browser like Mozilla or internet explorer for to log into your mail service ..and if you didn't deleted them ..they will be there.. Usually the mail domains ..keep the mails even in the trash folder for about a month ..so even if you deleted them by mistake you will be able to find them on the domain's web page ..
OR ..you just need to sign in again ..cause another person remained signed in ..or something like that ..
Just time the domain .in the search engine ..for ex..windows live ...or yahoo mail ..or what ever teh domain is..and the log in page will be displayed..Use your identification and password again and log into ..to read the mail ..
If you use a mail program ..like Thunderbird ..or outlook ...probably it is a communication with the server problem ..specially if it uses an smtp ..imap ..and not pop server to download teh mails and keep in computer ..

No internet connection


f your modem isn't getting an answer from your ISP
  • 1 Make sure that the cable is correctly connected to both a phone line and your modem and that, if you're using an external modem, it's connected to the PC.
  • 2 Dial the access number for your Internet service provider (ISP) with a regular telephone and listen for a data tone. If you don't get one, then you have the wrong number or your ISP is down.
  • 3 If your modem is internal, skip this step. Unplug the power cord from your modem and shut down your computer. Plug the modem back in and restart your computer.
  • 4 If you have another modem cable that you can use to connect the computer to the modem, swap it with your current cable to rule out a bad cable.
  • If your connection is refused by your ISP
  • 1 Make sure your username and password are still correct. These are usually entered through a connection program that your ISP provided. You will probably have to retype your password, as you won't be able to read it on-screen.
  • 2 Locate the TCP/IP settings for your computer. In Windows, these are found in the Network and Dial-up Connection control panels. In Mac OS 9.2 and earlier, they're in the TCP/IP control panel. In Mac OS X, they're in the Network section of System Preferences.
  • 3 Check that the host name and domain name information are correctly entered in the TCP/IP settings. This information should have been supplied by your ISP.
  • If your connection is accepted but you can't load Web pages or send e-mail
  • 1 Call your ISP's support number to find out if you have been affected by a service outage.
  • 2 Unplug the power from your modem (whether it's telephone, DSL or cable) for at least 10 seconds, shut down your computer, plug the modem back in and restart your computer.
  • If your connection seems too slow
  • 1 Set your Windows computer to MS-DOS mode: Click on Start, Programs, MS-DOS Prompt.
  • 2 Type "ping" followed by an Internet domain name--for example, www.google.com or www.yahoo.com. Macintosh users with OS X can use Apple's Network Utility program to "ping." Earlier versions of Mac OS don't have it built in, but freeware programs are available on the Web.
  • 3 You should get a report saying how many milliseconds it took for your "ping" to reach the destination. A computer communicating with the Internet via a 56-KBps modem connection might typically have a 0.3-second (300-ms) or longer ping. Anything longer than 5 seconds (5,000 ms) indicates a problem with your connection that might be the fault of your ISP.

    Oops! This page appears broken. DNS Error - Server cannot be found.


    The servers are located in the network by using it's ip address.
    Using names for the domains is easier for humans.
    A Domain Name Server (DNS) keeps track of the server ip address related with the domain name.
    When an error occurs finding the corresponding ip address for the domain name, youll get the message "Oops! This page appears broken. DNS Error - Server cannot be found.".

    HI While installing Vedio driver is trowing RPC server unava


    Hello sans_sankar,

    If it says RPC server is unavailable, that has to do with your internet connection.

    Check if both ends of your ethernet or USB cable are properly plugged in their ports on your modem or router to your computer.

    You can also turn the modem or router off for a minute then turn it back on again.

    Your video installation should be complete, otherwise, it might be incompatible with your computer.

    Hope that helps.


    Yours truly,
