R – MOSS 2007 site in a farm type initializer exception

exceptionmosssharepointsharepoint-2007

We have some solution that we built against a MOSS farm one of which includes a timer job. This job has been working just fine for months. Recently the administrator enlisted another server into the farm, and our timer job automatically started running on this new machine. As soon as this switch happened our timer job started yielding the error below (found this in the SP logs).

At first I thought it was a rights issue, but the timer service on the machine where it worked before and the new one are running under the same domain account. It seems to be failing while looping the site list in a site collection, on just one of the sites/webs (code snippet below). I know that this domain account has access to this because it works on the other box under same account. Does anyone have any ideas on why this cryptic error is occurring? Or if any special procedure needs to be done on this new machine to ensure it has proper ACL's for all databases in the MOSS farm?

Code:

public static void Main(string[] args)
{
    SPSecurity.RunWithElevatedPrivileges(delegate() { setInputParameters(); }); 
}

private static void setInputParameters()
{
    SPFarm farm = SPFarm.Local;
    SPWebService service = farm.Services.GetValue<SPWebService>("");
    foreach (SPWebApplication webApp in service.WebApplications) 
    { 
        foreach (SPSite siteCollection in webApp.Sites) 
        {   
            using(siteCollection)
            {
                siteCollection.CatchAccessDeniedException = false; 

                try 
                {
/* Here is the line that it fails on */
                     foreach (SPWeb web in siteCollection.AllWebs) 

Exception:

The Execute method of job definition LMSDataImport (ID 4b37b285-ef8a-407c-8652-391639449790) threw an exception.

Check the DLLs for SharePoint, do all exists and all are the same version? Try putting a catch for the TypeInitializationException, and see what is wrong inside that exception.
