MSMQ send works great under XP, fails silently on Server 2003

I have created an application that uses MSMQ on XP.   It is time to being deploying and testing the app.   I have found that when I copy the files to  Windows 2003 Server that nothing ever "shows up" in the queue.  

This is a transactional, private queue reference via the string: @".\private$\myQueueName"

The entire code is surrounded by try-catch blocks, but no error is ever thrown.

I have set the permissions to be as permissive as possible to try to get something to show up in the queue.   (Everybody has full control.)

I am using transactions and the transaction's commit statement executes without any problems.

The queue is created from code, but I have also tried creating it by hand to see if it makes any difference.

I encountered a post on eggheadcafe referencing this exact problem: msmq works under xp, fails under 2003.  Unfortunately, no solution was ever posted.  (http://www.eggheadcafe.com/forumarchives/msmqprogramming/Jun2005/post23331195.asp

        MessageQueue messageQueue;

        else

            messageQueue = MessageQueue.Create(AppConst.QUEUE_PATH, true);

                        

        MessageQueueTransaction mqTrans = new MessageQueueTransaction();

        

        
 

        mqTrans.Begin();

        try

        {

            messageQueue.Send(new Message(strXml,new XmlMessageFormatter()));

            mqTrans.Commit();

            {

                TextWriter tw = File.AppendText(AppConst.QUEUE_TRANSACTION_LOG);

                tw.WriteLine();

                tw.Close();

            }

        }

            {

                TextWriter tw = File.AppendText(AppConst.QUEUE_ERR_LOG_FILE);

                tw.WriteLine(ex.Message+ex.StackTrace+ex.StackTrace+ex.ToString());

                tw.Close();

            }

            mqTrans.Abort();

        }

        finally

        {

            messageQueue.Close();

            payloads.Clear();//Once you send to queue the Collection of payloads gets emptied

        }

Just discovered that the server that this is running on is Windows 2003 Server SP1.   Could this be the entire problem?

This error had to do with the fact that the virtual server that this app runs on ran out of memory and became corrupted.
