Windows 2008/Exchange 2007 Event 4001: A transient failure has occurred. The problem may resolve itself in awhile. The service will retry in 56 seconds.


Today I was installing Exchange 2007 SP1 on an HP Proliant DL380 G5 server running Windows 2008 x64. After the installation and reboot, I kept receiving the following error in the Event log:

Event ID: 4001 Source: MSExchange System Attendant Mailbox

A transient failure has occurred. The problem may resolve itself in awhile. The service will retry in 56 seconds. Diagnostic information: Could not find any available Domain Controller.

I did exhaustive research and finally came across this thread, which suggested updating the Intel NC110T NIC drivers and disabling the checksum offload options on the server’s network card. I was already running the most recent version (9.10 dated February 25 2008) of the HP driver for the Intel NIC, but did disable all the checksum offload options.

Following a reboot all of my Event 4001 error messages disappeared. The local administrators are going to open a support case with HP to try to determine some type of resolution that does not require disabling the NIC’s checksum offload options.

    I fixed this issue today myself… had to do with IPV6 being disabled, but it’s not disabled correctly.

    Go to the following key in the Windows 2008 Machine

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters

    Create if there is not one a DWORD (32 Bit) entry with the following payload

    Dword Name = DisabledComponents

    Payload = ffffffff

    (that is 8 f’s)

    It will register as 0xffffffff as a hexidecimal value.

    Reboot. This resolved my issues with the Mailstore not coming online after disabling IPV6 in the network adapter.

    This can be used in Vista and Windows7

    Although I was seeing this event in my viewer I was experiencing different issues that led me to correct this 4001 problem. My original issue was with Outlook 2010 connecting to Exchange 2007. I could not connect to the mailbox server for some reason. Anyway, I have a Dell T105 server and I updated the NIC drivers (per your suggestion of updating the nic driver on your HP) and viola..!!! I could start making connections to the Exchange box and set up my profile without a problem…funny how some things can affect other processes… :o)
