Entweder:

oder
1. Open the home server console via Remote Desktop
2. Click skip when you get the error
3. Close the console window
4. Open the log directory c:\Documents and Settings\All Users\Application Data\Microsoft\Windows Home Server\logs and look for the most current log named HomeServerConsole.*****.log
5. Open the log file and look for any unfinished DLL errors. In my case the log file showed:
[1]090520.102356.6875: UI: Error: Unfinished DLL: HomeServerConsoleTab.Storage.dll. User chose to block.
[1]090520.102401.2343: UI: Error: Unfinished DLL: HomeServerConsoleTab.HPSU.dll. User chose to block.
6. Go to the WHS application directory: c:\Program Files\Windows Home Server and rename all DLLs referenced in the log file as being unfinished.
7. Open the home server console again. You the error message will not be displayed, but your tabs will still be missing.
8. Close the console
9. Go back to the application directory and rename the DLLs from step 6 above back to their original names.
10. Re-open the console. You should have the tabs back again.
