Hi Norbert,
Normally (at least in the environments I work in) when logging on to a Windows system you use DOMAIN\User-ID. Then when you perform the installation of Tamino, which will install the System Management Hub (SMH), the windows login ID (DOMAIN\User-ID) is set as the user with Administration rights for the SMH and Tamino.
Make sure (confirm) that you are using the same user-id to login the SMH as you used to logon the Windows system when you performed the installation, i.e., DOMAIN\User-ID. Hope this helps.
Rob
