    No Logon Servers

    Hi,

    I've been trying to fix this for a few weeks now but we occasionally get no logon servers on some of our computers.
    Not always the same computers and a rest normally fixes it.

    It started after our PDC crashed beyond repair and i had to build a new one and reclaim all roles etc on the secondary DC.

    I have reimaged the computers in question in the hope that it was something stored locally on the machines but this hasn't fixed the issue.

    I'm hoping someone here can point me in the right direction for tracking this issue down as it's starting to grate.

    Any help would be greatly appreciated!

    My first thought was DNS, it's always DNS.

    Check the old DC isn't still in there somewhere. check the _msdcs and pdc folders

    You could check the NTDS settings in Active Directory Sites and Services for signs of the old server.. see if the new DC is still trying to replicate with the dead one ?

    DNS is completely clear of the old server.

    I did find in Name servers 2 records for my new server dc1.FQDN AND dc1.(with no FQDN)
    I have remove the latter and lets see if that makes a difference.

    Other suggestions still welcome

    Are the computers connected via ethernet or wireless?

    We get the same occasionally. haven't got to the bottom of it. I also demoted a DC a few months back but there are no signs of it remaining in DNS.

    This:

    Delete Failed DCs from Active Directory

    Just posted this in the Window 7 Netbook thread and it was only relevant for our laptops and netbooks over wireless, but I thought I would still share. We have luckily never had this issue on a PC, yet.
    What we have found is that students (and staff) are impatient. They shutdown and close the laptop/netbook and hand them in before the device has finished shutting completely down.
    We have told the schools to make sure that the devices are fully off but they never do so if this happens now, we just get them to pull the battery out of the device and try again.
    Works everytime.
    Another suggestion would be logging in as local admin and running the "Join a Domain or Workgroup" wizard. This has helped fix some Trust Relationship issues we have had. Might be worth a try.

    Also have a look through ADSI Edit - you may have entries floating around in there which aren't showing in AD or DNS.

    Since they are wired: I've seen this issue happen a lot when replacing a computer, or upgrading from XP to 7 or whatever. Almost anytime a new computer is put in place of an old one.

    The problem I found was that DNS and Reverse DNS was still holding the old computers IP address, and the new computer is trying to use the same IP. The solution was to delete the old IP out of DNS and reverse, and set the new computer to DHCP vs. Static.

    Have you tried enabling the Group Policy setting "Always wait for network at computer startup and logon"?

    Computer Config > Admin Templates > System > Logon
