I have done the following so far1. tried to replace ACSE.TPLfrom 2003 compact dis into mtadata but no luck2. manually created max log size registry for MTA but as soon as you restart the MTA resouce it automatically got deleted from registry

Hi Prakash,Please check below URL, I am not sure whether we can test this on cluster env:Have you done any changes in cluster recently ??? is yes then please revert back.http://support.microsoft.com/kb/840469Anil

Looks like MTA is lacking out of resources. the best thing would be here to failover to other node and check if you can bring MTA online. Donot copy and replace file until you have not done full testing with failover MTA is not required in pure EX2003 environment as it was used by legacy exchange servers.

Tried to move on other cluster nodes and its not coming online.

Hi There,I would start with ExBPA first of all to see if there are any problems that ExBPA can figure out for me. Then I would try with http://support.microsoft.com/default.aspx/kb/917139. Milind Naphade | MCTS:M | http://www.msexchangegeek.com

Milind, thanks I ran EXBPA and its not shoiwng any critical error for exchange, its only showing warning and those are also relates to hardware.. and Also tried given link the registry got automatically deleted once i restart the MTA cluster resouces.

Okay. Thanks to let us know again. Can you check followings?Make sure the antivirus exclusions are set correctly. Check to see if the MTADATA folder has correct permissions on it.See if the MTA service has correct logon credentials. Should be a Local Service normally.Can you also increase the diagnostic logging on MTA service on affected Virtual Server? Paste the new logs here.Also, check to see if the IIS metabase is okay.Milind Naphade | MCTS:M | http://www.msexchangegeek.com

Guys,I found the culprit, ACSE.TPL was missed from MTADATA 1. Confirm the MTADATA\RUN path from registry. HKEY-system-current control set-services-MSEXCHANGEMTA-parameters-MTA RUN directory2. Go to RUN directory and checkACSE.TPL that its there or missing.3. If it is not there there replaced this file from any other server, Make sure creation date should be 02/02/1998, Thoughbelow MS article says replaced *.TPL file from exchange compact disc but its only worked for me when i replaced ACSE with 02/02/1998.http://support.microsoft.com/kb/1543854. Restart the MTA resource.

Hi,Thanks for your sharing and glad to hear the issue is resolved by self.Allen
