andreicek , Your problem sounds unfamiliar to me but by experience, do the following checkup, Make sure you have all drivers installed, Make sure your anti-virus is updated Make sure that the installation was done successfully, The above might sound minor but i am trying to eliminate all possiblities. Next, go to >Start >Run and type mmc, then >Enter. In the mmc consoloe go to >File and select Add/Remove snap-in from the menulist. In the "Available snap-ins" section scroll down and select >Server Manager, then click on Add> button so that it appears on the right side. Click Ok to exit and return to the initialised console containing the selected snap-in. You should be able to access all the functionality of the server manager from the mmc or the Microsoft Management Console! If this works, make sure that you save the console before closing it. It might also mean that you will have to be using it until you fix the >server manager from Admin tools on the start menu. If this doesnt help. According to my experience with Microsoft, checklist system requirements before re-installing again. And by the way, you could re-install the Admin Pack.msi to fix the issue. Let me know how it goes.
