An officemate approach me because of the message appearing when he try to login to his workstation. "Windows cannot connect to the domain, either because domain the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear, contact your network administrator for assistance.". For this error message, i've done the following steps:
- 1. Login to the Windows XP workstation as a local administrator. If you cannot logon as local administrator, try to disconnect the network cable and login to the computer by using a domain administrator user that was used to logon on the PC before. This will be made possible because of the cached logon credentials feature that remembers the last 10 successful logons.
- 2. Go to Control Panel, then click on System icon, then go to Computer Name tab. You can also do this by right-clicking My Computer, and then Properties.
- 3. Remove the computer from the domain by clicking on “Change”. You should see that Domain button is now selected. Remember your domain name in the text box. Select the “Workgroup” radio button to remove the computer from the domain, and put any workgroup name in the text box (e.g. workgroup).
- 4. Click OK to exit and reboot the computer.
- 5. After the computer restarts, go back to Control Panel > System > Computer Name tab, and click Change.
- 6. Rejoin the domain by chocking the Domain button. Enter the domain name noted in step 4.
- 7. You might be prompter to enter the credentials of one of the Domain Admin users. This can be bypassed if one of the Domain Admins manually creates a computer account in Active Directory Users and Computers for the workstation you're about to join.
- 8. Click OK to exit.
- 9. Reboot the PC.
