VSS Event ID-13 MOSS 2007- The Old Domain Account is referenced

After we made changes to the “moss user”  domain user account (created a new account as the previous account gets locked out every 30 min) found these VSS Error Event ID-13 in the application event log:

Event Type: Error
Event Source: VSS
Event Category: None
Event ID: 13

Time: 8:49:57 PM
User: N/A
Computer: MOSSSERVER
Description:
The user name domain\mossuser specified in registry (SYSTEM\CurrentControlSet\Services\VSS\VssAccessControl) does not map to a real user name. The entry is ignored.

To Resolve:

Ensure that the VssAccessControl key specifies a valid account
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To ensure that a valid account is specified for the VssAccessControl registry key and delete accounts that are not valid:

Caution: Incorrectly editing the registry might severely damage your system. Before making changes to the registry, you should back up any valued data.

1.Click Start.
2.In the Start Search box, type Regedit, and then press ENTER.
3.Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\VssAccessControl.
4.To delete an account that is not valid, right-click the name, and then click Delete.
5.To add a new valid account, right-click VssAccessControl, click New, and then click DWORD (32-bit) Value.
6.Give the registry entry the same name as the user account.
7.Right-click the registry entry name, and then click Modify.
8.Type 1, and then click OK.
Note: You must set this value to 1. If you set it to 0, the Volume Shadow Copy Service is prevented from using the specific user account.

Verify
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the Volume Shadow Copy Service is started:

1.Click Start, point to Administrative Tools, and then click Services.
