I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Dependent's are
Windows Event Log
and Server

If i have to pick 1 suspect - it is RPC
Make sure it is started as a network service.

Also ensure microsoft exchange hub transport is started as a Network service.

Rest all are local system account.

Sunnyc7- All of the above are as you want them to be.
Still no joy.
The registry may have been modified incorrectly, or some how got corrupted.
There may be a service in the registry under the following registry key:

In the right pane, right-click "DependOnService", and make sure that there are no umwanted resources listed there.
if you find that there are some unwanted services listed in the above mentioned Key then take a backup of the registry and then remove it from the registry and try to start the MSexchangeSA service
