Not able to joinVista Bussiness Machines to 2000 Domain.I keep on getting access denied errors - even when using main administrator account. Problem seems to be intermittent.

Hi, Please confirm if only Windows Vista client workstations encounter this issue. I suggest checking the following points for troubleshooting: 1. Make sure that SP4 has been installed on all the Windows 2000 Domain Controllers. 2. Verify the Authenticated Users has the permission Add workstations to domain. 3. I wonder if the main administrator account is the domain Administrator. If not, please join the domain with domain Administrator and check the result. 4. Try pre-create the users computer account in Active Directory Users and Computers.1) From the Active Directory Users and Computers snap-in, right-click the container where the account resides.2) Click New, and then click Computer.3) In the Computer name box, type the name of the Windows 2000-based computer that you want to add to the domain. Make sure the computer's name is also entered in the Computer name (pre-Windows 2000) box (this should occur automatically). 4) Click Change. Select the user or group that will be joining this computer to the domain, and then click OK.5) If you want Windows NT 4.0 and previous operating systems to use this computer name object, click to select the Allow pre-Windows 2000 computers to use this account check box, and then click OK. If the issue persists, please export the Netsetup.log for further research.

Thank you - option 2 did it for me - I had unknown account entries in the AD - deleted them and re-added administrator and myself. Have a nice day
