WSUS Sql timeout for GetUpdates() method invocation

Hello,

I have a simple VB program that fetches the update collection from WSUS (Windows Server Update Services) via the Microsoft.UpdateServices.Administration's AdminProxy.GetUpdateServer.GetUpdates() method (see the code snippet below).

About half the time, this program fails with the following timeout error (see below for the full stack trace):
     Error text: Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

I am running on "Windows Server 2003 Standard Edition Service Pack 2" with 1GB of memory.

I am running the following version of WSUS:
Microsoft Windows Update Services Version 2.0.0.2620 / Windows Server Update Services Service Pack 1

Here is the complete stack trace:
Getting list of updates
An error occured:
Error text: Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

The .vb code is listed above.  There is no way to increase the timeout via the Microsoft.UpdateServices.Administration object (that I can see).  That object abstracts all the underlying sql connectivity stuff for the SUSDB.

The other link you gave refers to a solution resolved with WSUS SP1, as I understand it.
