The server process could not be started because the configured identit

[AndrewG1976]

I'm finding from time to time my COM+ application dies, if I try to restart it manually I get the error:

Catalog Error
An error occurred while processing the last operation.
Error code 0x8000401a - The server process could not be started because the configured identity is incorrect. Check the username and password..

The event log may contain additional troubleshooting information.

The user that's starting the service is a local user with admin rights.

To resolve the problem all I need to do is to re-enter the password in the "Identity" section of the Properties for the COM+ application.

It seems like somehow the password is being deleted or changed which leads to the application not being able to restart.

This happens after some time when everything has been running OK.

The error in the System Event Log is

DCOM got error "Logon failure: the user has not been granted the requested logon type at this computer. " and was unable to logon <SERVER>\<USER> in order to run the server:
{61B67962-8457-4477-8B7D-E01A1DCDAC72}

The Security Event Log states:

Logon Failure:
 	Reason:	The user has not been granted the requested
 		logon type at this machine
 	User Name:	<USER>
 	Domain:		<SERVER>
 	Logon Type:	4
 	Logon Process:	DCOMSCM 
 	Authentication Package:	Negotiate
 	Workstation Name:	<SERVER>

Any ideas what could be wrong?
