Thanks ManU, I have seen that post before (and also http://technet.microsoft.com/en-us/library/cc774289(WS.10).aspx) but as we used to be able to run the shell command beofre.

I need to say that I have never done uninstall/install Exchange before, so any KBs, informations are welcome :-S Thanks again

Hello, It is not a simple task to Uninstall and recreate the entire thing. I can recommend you some other things like Run IPconfig / flushdns and nbtstat-R Re-run the cmdlet Hope this will help Regards from www.windowsadmin.info

hello ManU PhiliP , I tried: Run IPconfig / flushdns and nbtstat-R Re-run the cmdlet But it did not solve the issue and neither restarting the lanmanserver service. ************************ Whenever I type the below shell command on my mailbox server:New-StorageGroup -Server SerEXch01 -LogFolderPath R:\RSG\Logs -Name RSG -SystemFolderPath R:\RSG\Datas -Recovery I got the below error message: Event Type: ErrorEvent Source: DCOMEvent Category: NoneEvent ID: 10006Date: 5/9/2007Time: 10:01:01 AMUser: N/AComputer: CFI-VISUALDescription:DCOM got error "Class not registered " from the computer 192.168.xxx.xxx when attempting to activate the server:{8BC3F05E-D86B-11D0-A075-00C04FB68820} Any Idea?? I haven't found anything to fix the issue on Internet

Here the solution: After a long investigation I found that link: http://www.homeserverland.com/wiki/w/whs/rpc-server-unavailable-error-0x800706ba.aspx Here the description: RPC Server Unavailable Error 0x800706ba The Windows Firewall (formerly known as Internet Connection Firewall) service and Distributed Component Object Model (DCOM) can cause access denied errors (such as an "RPC Server Unavailable" error - 0x800706ba) when trying to use the Grid Junction Custom Action scripts to shutdown remote clients using WMI scripts. The solution to fix the RPC Server Unavailable" error - 0x800706ba, log in as Administrator and click on Start – Run and type: Netsh firewall set service RemoteAdmin --> that command did not work at first because the firewall service was not started, so I restarted the SharedAccess service and ran again the command "Netsh firewall set service RemoteAdmin" It has solved my pb to create a new Storage group :-D Really hope it could help some of you!!
