Exchange 2010 and Netbios domains with dotted notations

  • Article

We've had a small number of cases come in where customers are unable to manage their Exchange 2010 environments via the Exchange Management Console. Attempts to do so result in the following error:

"Initialization failed
The following error occurred when getting user information for 'domain.com\alias':
The operations couldn't be performed because object 'domain.com\alias' couldn't be found on 'somedomaincontroller.domain.com'. It was running the command 'Get-LogonUser'."

This issue can occur when the Netbios name for your domain contains a dotted notation. Generally, Netbios domains traditionally are one word values (in the sense of what we consider as "Internet" domains, such as DOMAIN. Netbios domain names, however, supported a character set which included the period, '.' and so there are a number of organization out there who may have had their Netbios domain name set up as DOMAIN.COM, or COMPANY.DOMAIN, or any such combination that included a period or "dotted" notation.

You will need to contact us for an Interim Update that can be applied to resolve this issue. It should also be fixed in Exchange Server 2010 RU4 but at this time, we haven't gotten RU3 out the door so it will be a few months.

I've also seen this resolve issues with ActiveSync to back end E2K3 servers given the same "dotted" Netbios domain. Given that there are a number of potential components in Exchange that this could impact, if you have a dotted Netbios domain and are having some very odd problems with Exchange 2010, please give us a call (or apply RU4 if it's available when you read this).

 Note: You MUST open a support incident with Microsoft Exchange Server Support. To make this as easy as possible, please refer to KB 981033 and provide the Exchange Rollup version you are currently running to get the correct fix.

EDIT: Exchange Server 2010 RU4 is now out, see https://msexchangeteam.com/archive/2010/06/17/455191.aspx. It contains the fix to resolve this issue.

    We now have Interim Updates available for RU1, RU2, and RU3 but you will need to call into open a support incident with Microsoft Exchange Support.  Refer to KB 981033 which hasn't been published publicly yet. RU4 is still slated to have this fix included.

    Hi I had this issue in my test lab of Exchange Server 2010 initialization failed because the user was not find it was running Get-logonuser. This usually happens in Hyper-V or another Virtualization software, when the same Image that was created is used without Sysprep, EMC will not start if the Machine SID conflicts with Virtual Machine or Host. To sysprep try to go to c:windowssystem32sysprep, and make sure you check GENRALIZE. This helped me while i spend a week doing research on this issue. Hope it will help you.
