Mapped Network drive - "The target account name is incorrect"

Posted on 2014-08-26

I have a strange issue, that i cant seem to find a fix for it.

i demoted one of the old server and setup a new server with a new name e.g server2 the old name of the old server was server1.

beacsue its a file server and users already have drive mapped under the old server name, i created a Alias CName and pointed server1 to server2. This works fine for all OS except when i try to map a drive on 2003 server e.g \\server1\drive it throws that error?

note- if i map it with a new name \\server2\drive on server 2003 it works! (so its the Alias CName that it dont like?)

im sure there is some sort of registry edit i need to edit on server 2003 wich should fix this issue?

please help?

    on the windows 2003 server try flushing your DNS cache.

    ipconfig /flushdns

    For this to work, I believe you need to:

    1. Demote the original server (if it was a domain controller)
    2. Change the original server to be in a workgroup (if old server is still online)
    3. Delete the original server from Active Directory (do this even if step 2 could not be completed)
    4. Ensure there are no additional DNS entries in the system for the old server1 other than the alias you created.

    My guess is that there is still a server named server1 in Active Directory.  This happened to us a few times when a tech forgets to delete the old server account.

    Try this

        Edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters and add a value OptionalNames of type Multi-String
        Add in a newline delimited list of names that should be registered under the NetBIOS browse entries
            Names should match NetBIOS conventions (i.e. not FQDN, just hostname)

    and restart the fileserver
