Accounts Missing After Migration with DSMN (189441)


The information in this article applies to:

  • Microsoft Services for NetWare 4.0
  • Microsoft Windows NT Server 4.0
This article was previously published under Q189441

SYMPTOMS

You install Directory Services Manager for NetWare (DSMN) on a Windows NT primary domain controller (PDC) to manage the account database on NetWare servers centrally from the Windows NT domain.

After you have finished migration, you notice that some groups and users are not replicated properly. For example, you delete members of a group on a NetWare server using SYSCON and start a full replication, but the users do not appear in the member list.

Also, when you run the DSMDUMP utility, you will see that several groups are missing from the Jet Database. This utility ships with DSMN but is not installed by default.

You will receive the following error in the application event log: 
   Event ID 8005
   MSSYNC

   The Sync Agent Service change log thread failed to find the last change
   log entry it processed. Some user and group modifications might be lost.

CAUSE

Although DSMN detects that it has missed some changes to the Security Accounts Database (SAM), it currently only logs this event.

RESOLUTION

To prevent the problem, set ChangeLogSize to the maximum value.
There are workarounds available after the problem already exists.

  • Re-create the affected groups. To do this:

    1. Remove all NetWare Servers from DSMN so the NetWare object IDs are retained later.
    2. Select the group in User Manager for Domains and press F8 to create a copy of the original group.
    3. Enter a name for the new temporary group.
    4. Delete the original group.
    5. Select the temporary group and press F8 again.
    6. Enter the name of the original group and press ENTER.
    7. Repeat the above steps for any groups missing in the output of DSMDUMP.
    8. Add the NetWare servers in Synchronization Manager; do not migrate user accounts.
  • Reinstalling DSMN


This may be easier for you if you only have a few NetWare Servers. The main problem here is that you lose the NetWare password settings if you don't have FPNW running on the server. To prevent password changes in the Windows NT domain while DSMN is not running it might be a good idea to set Netlogon to Manual startup and to stop it before removing DSMN. After you reinstalled DSMN, add the NetWare server without migrating the accounts.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
