Hi, Kindly look into this article: http://support.microsoft.com/kb/940845 or you can try this: My solution was to edit the registry 1) add a delay (bootpause) to SA with the following registry entrery [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA \Parameters] "BootPause"=dword:000000b4 2) make IS depend on SA via the following registry modification [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS] add "MSExchangeSA" to the list of values in "DependOnService" as always, backup your registry first Ripu Daman Mina | MCSE 2003 & MCSA Messaging

Hi I did manage to get it started after stopping the msexchange monitoring service. It stayed started for about two weeks. It is now failing to start with the same error. Article http://support.microsoft.com/kb/940845 does not seem to apply to me as I cant even start the service manually.

There are a couple of reasons why you get this error message. Lets gather some more information please Ø Check DNS setting and ensure that it configured correctly. Ø Check the network binding order and ensure that it is configured correctly. Disabled network cards that is not needed Ø Run an ExBPA against the Exchange Server Ø Run dcdiag http://technet.microsoft.com/en-us/library/cc773199(WS.10).aspx Ø Run NetDiag http://www.microsoft.com/downloads/details.aspx?FamilyID=1EA70814-7E6C-46E5-8C8C-3C439A732E9F&displaylang=en&displaylang=en If you can share any any errors, it would be very helpful Check out my blog @ http://cb5.com/blog Chris cbfive.com
