    Serious Issue with unresponsive servers!

    We have a serious issue with 3 servers (2 DCs and 1 Exchange Server) where the server becomes totally unresponsive. Users can't log on and generally everything starts to fail. When we visit the server, the login box has disappeared and the only thing we can do is a hard reset, this issue has been going on for nearly 6 months now, it started with 1 server and has now affected 3!

    It happens at almost random intervals and SLT are starting to get seriously annoyed and we have no idea what the issue is. In addition to this, Ofsted is due soon, probably next month, so... I think that explains that!

    The 2 domain controllers are 4 year old IBM eServer MT-M 8670-L1X. Specs:
    Dual Intel Xeon 2.80GHz
    4Gb RAM (3.81Gb Windows)
    Windows Server 2003 R2 x86

    The Exchange Server - HP Proliant DL380 G5 (Will have to confirm this, but it's something similar!)
    Dual Intel Xeon E5320 1.86GHz
    6Gb RAM
    Windows Server 2003 R2 x64

    At first we thought the 2 DCs would need replacing, however, the mail server is brand new and giving the exact same issue.

    Does anyone have any ideas what could be the problem? We are desperate!

    It definitely sounds like some sort of corruption to me, affecting critical services DNS/DHCP possibly even AD itself. I would highly recommend you check the event logs for any clues. I would also (if possible) run Scandisk (especially on the system drive) to check for errors.

    How long has this problem been going on for? What Service Pack are you running on your servers? What AV software do you use? Have you scheduled an over night scan?

    (Updated the first post!)

    Service Packs: SP2 on all servers, latest updates through WSUS.
    Anti-Virus: Sophos (LGFL Agreement) Scans every morning at 5am.

    I can't make sense of anything really bad in Event Viewer. Can I export the logs somehow?

    The event logs should give clues as to whats going on, also check for out of place processes within taskman or possibly even use process explorer from sysinternals to take a look.

    You can export the logs, within even viewer select the log then right click and select save log file as.

    Sounds like something bad is being replicated around AD if the new mail server started doing it.

    I've had servers do the exact same, when they have run out of space on the system drive, but you normally get items in event logs for this,

    Could be a bad Active Directory? ~Beaten to the post by Bizzel

    I forgot to mention the Exchange server is on a totally different domain from the 2 DCs. (2 DCs is Curriculum and Mail Server is Admin - Both separate Forests)

    When the problem occurs does it affect all boxes at the same time?

    Have you tried running DCDIAG and NETDIAG on all of the boxes?

    Here's a KB about the login box disappearing.

    No Windows or Network Logon Dialog Box at Startup

    Not tried those, but no, it doesn't affect all 3 at the same time.

    Yes there is and I've asked the NM, he thinks there are 2 Global Catalogues.

    I've got the Event Viewer logs from 1 of the DCs if anyone is interested in having a look, but zipped it's 11Mb so might have to be a email or FTP job!

    I'd try running them and viewing the output then. I'd also run rootkit revealer and concider running a scan with different AV if you can or even trying temporarily disabling your current product.

    Thanks for your help guys. I'll give these things a try tomorrow, Right now I've gotta run home. Daughter has thrown up nearly 10 times today. Just hope she gets better before the evening. I was supposed to bring her in to school tomorrow for an event and everyone is so looking forward to seeing her! Moral dilemmas! Professional dilemmas! Argh!
