    When I go to connect a workstation to the network I right click on My
    Computer on the workstation and then click 'computer name'. I then click the
    'change' button. I add the domain name in the domain field and enter the
    admin UN and PW, the response is an error that says "The following error
    occured when trying to connect to a1asigns.local
    The format of the network name is invalid"

    Please help. It feels like I'm in hell today :(

  4. Hi Troy,

    Which error did you get? Post the ipconfig/all from the server and one from
    a client.

  6. Are you certain that when you did your Install that you did not have a Space
    anywhare in the Domain Name! At what point in connectcomputer did you get
    the error, When you logged in or after you selected Computer name and users?

  7. Hi Troy,

    If you only have 1 nic in the server, NetBIOS over TCP/IP should be enabled.
    DHCP is not configured right. It should have 006 and 044 pointing to the
    server IP, 003 to the gateway IP, 015 to the local AD domain name and 046
    should have 0x8 as value. Put the workstations to obtain an IP and DNS
    automatic from the SBS DHCP server.

    Hi Frank,

    There is no space in the domain name or the server name. All my workstations
    are named WS1,2,3...

    When I use connectcomputer I get stopped right after I 'enter a username
    that has permission to join the domain'. Then The error I get is 'The list of
    users and computers could not be found on the server. Make sure that the
    Small Business Server network adapters are configured correctly'

    I have the server running DNS and DHCP and switched over the workstations to
    get automaticaly.

    Still nothing. I get the same error as I did before.

    I did that and the error below occured:

    When I try to run connectcomputer in IE I get the error:

    'The list of users and computers could not be found on the server. Make sure
    that the SBS network adapters are configured correctly'

  10. First I would say that you would find it a lot easier to set up with two
    NICs in server but with one NIC follow Marina's advice. At this point I
    would remove all the computers from Server Management and add them back in
    and try again.

  11. Is there a hosts file on the workstations
    (C:\windows\system32\drivers\etc\hosts) that has an entry for the
    servername?

    If so, remove it that entry in the hosts file.
