Couple of follow up questions:

1. What version of exchange environment is provisioning task running against?
2. Is provisioning task using VSA like remaining tasks in environment?
3. Does the provisioning task reports contain any error? The're stored in <EV Installation Folder>\Reports on EV server that is holding provisioning task.
4. If you try to take a DTrace of Provisioning task while trying to run the provisioning and share the logs with us, that should help.

Thanks !

Follow up answers:

1. Exchange 2007 is running in the environment.
2. Yes it is using the VSA.
3. The provisioning task reports simply stop. The last file that was logged shows no errors, after that there are no others logged for provisioning.
4. Can't run a DTrace from EV itself, getting a "required component is missing from the Administration Console installation" error trying to open the console.

Have run a command line DTrace which returned the following:

=====

Alan,

Dtrace which you pasted is empty, so i would recommend you to take another dtrace and also let us know the event description.

I am not sure at this point if below technote is applicable in your case (as MIN said, the DTrace log is empty & you're using 9.0.4) but worth a look:

http://www.symantec.com/business/support/index?page=content&id=TECH78282

I am unable to try and run the task from the console as now I am unable to access it, so all I have been able to do is to run DTrace from the command line. I

s there any way that I can try run the task from the command line?

Tony,

I'm not quite getting the same errors logged, however I am getting a "parameter 'exePath' is invalid" error which I would presume will be a related issue to that article?

That is why I said it was similar.  In looking at the trace you posted I didn't see InstallPath under \Install from the registry.

It is quick and easy for you to check.

Also, another thing you could try is re-running Setup.exe for EV 9.0.4 to re-register everything. 

Looks to me like the client has been installed on the server, and that's mucked everything up on the server from.

I'd suggest a backup, and reinstall of the EV binaries.
