Did you try rerunning Setup?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

yes.. even i uninstalled everything and resinstalled but the same problem :(

THis is what i get when i open the management console: The following error occurred while searching for the on-premises Exchange server: [domain.com] Connecting to remote server failed with the following error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic. It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true -CurrentVersion 'Version 14.1 (Build 218.15)''.

Have you prepared the AD for the installation? Try to do it manually http://technet.microsoft.com/en-us/library/bb125224.aspxJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hi Jonas I tried the ad preparation but itt keeps on prompting me that the exchangge is not stable and i need to recover. When I perform m:recoverserver i get the below : [12/18/2010 21:02:40.0485] [1] Configuring an existing product. Product code: {4934D1EA-BE46-48B1-8847-F1AF20E892C1}.

Exchange 2003 run in native mode ?

You might try flattening the machine, removing the computer account and rebuilding the entire server from scratch.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

But he will steal hat to clear AD of all Exchange 2010 object. Problem is that he must run Forest and domain prepare manually on schema master , and don't forget legacy switch. HE can then delete all object of old Exchange 2010 server, and then go from there. And if machine is Virtual, set all drive fix size and memory should be multiply of 1024. And no AV software !

Hi, Please try above suggestions. If the issue persists, please check Event Viewer and post the error message in Application log for research.

Hmm, Try the below I am sure it will work Delete the Server Name from Adsiedit.msc Rename the Exchange Server Folder which would be in C drive (By Default) Run Setup.com /preparead Star the installation and it should be fine... If it fails with same error than you need to disable the IPv6 on the Exchange serverGulab | Skype: gulab.mallah
