Windows 2000 domain with non-default, or Windows 2003 and Windows Server 2008 domain with default, security permissions

Installation of WebSphere MQ behaves differently on these operating systems depending on whether a local user or domain user performs the installation.

If a local user installs WebSphere® MQ, the Prepare WebSphere MQ Wizard detects that the local user created for the IBM® WebSphere MQ Windows service can retrieve the group membership information of the installing user. The Prepare WebSphere MQ Wizard asks the user questions about the network configuration to determine whether there are other user accounts defined on domain controllers running on Windows 2000 or later. If so, the IBM WebSphere MQ Windows service needs to run under a domain user account with particular settings and authorities. The Prepare WebSphere MQ Wizard prompts the user for the account details of this user. Its online help provides details of the domain user account required that can be sent to the domain administrator.

If a domain user installs WebSphere MQ, the Prepare WebSphere MQ Wizard detects that the local user created for the IBM WebSphere MQ Windows service cannot retrieve the group membership information of the installing user. In this case, the Prepare WebSphere MQ Wizard always prompts the user for the account details of the domain user account for the IBM WebSphere MQ Windows service to use.

When the IBM WebSphere MQ Windows service needs to use a domain user account, WebSphere MQ cannot operate correctly until this has been configured using the Prepare WebSphere MQ Wizard. The Prepare WebSphere MQ Wizard does not allow the user to continue with other tasks, until the Windows service has been configured with a suitable account.

If a Windows 2000 domain has been configured with non-default security permissions, the usual solution to enable WebSphere MQ to work correctly is to configure it with a suitable domain user account, as described above.
