Error message when you query the log files in ISA Server 2004, Standard Edition

When you query the log files in Microsoft Internet Security and Acceleration (ISA) Server 2004, Standard Edition, the query stops. Additionally, you may receive an error message that resembles the following error message:

This problem occurs if the following conditions are true:

• The queried data and the query result contain lots of data. For example, the query result contains more than 500 megabytes (MB) of data.
• The ISA Server computer logs data to a Microsoft SQL Server Database Engine (MSDE) database.

A time-out occurs in the ISA Server logging component when a query runs for a long time.

Note This problem does not occur in ISA Server 2004, Enterprise Edition.

To find the difference between UTC and local time, use the Time Zone tab in the Date and Time item in Control Panel.

Post-hotfix installation information

After you install the hotfix, the default MSDE time-out period for a query is 150 seconds. However, you may change the MSDE time-out period by using a script. To do this, follow these steps:

1. Copy the following code, and then paste it into Notepad.

   Option Explicit
   Dim root
   Dim arr
   Dim logging
   Dim objArgs
   Dim WriteMode
   WriteMode = false
   Set objArgs = WScript.Arguments
   If objArgs.Count > 0 Then
   	WriteMode = true
   End If
   'Create the root ISA Server object
   Set root = CreateObject("FPC.Root")
   'Get the arrays collection
   Set arr = root.GetContainingArray
   Set logging = arr.Logging
   WScript.Echo     "***************************************"
   If WriteMode Then
   	WScript.Echo "* Set MSDEQueryTimout value (seconds) *"
   Else
   	WScript.Echo "* Get MSDEQueryTimout value (seconds) *"
   End If
   WScript.Echo     "***************************************"
   WScript.Echo	 "Retrieve the current MSDEQueryTimeout value:"
   WScript.Echo     "Syntax: ""cscript.exe MSDEQueryTimeout.vbs"""
   WScript.Echo	 " "
   WScript.Echo	 "Set the MSDEQueryTimeout value:"
   WScript.Echo     "Syntax: ""cscript.exe MSDEQueryTimeout.vbs 500"""
   WScript.Echo	 " "
   WScript.Echo	 " "
   If WriteMode Then
   	Logging.MSDEQueryTimeout = CInt(objArgs(0))
   	logging.Save
   	WScript.Echo "MSDEQueryTimeout = " & logging.MSDEQueryTimeout
   Else
   	WScript.Echo "MSDEQueryTimeout = " & logging.MSDEQueryTimeout
   End If
   

2. Save this Notepad file as MSDEQueryTimeout.vbs.
3. Run the following command from the location where you saved the file:
   Cscript MSDEQueryTimeout.vbs Time
   Note Time is the new MSDE time-out period that you want to specify in seconds. The default MSDE time-out period is 150 seconds.

There is no reliable workaround for this problem. The problem depends on the following factors:

• The size and the number of databases to be scanned
• The load on the ISA Server computer that is queried

For example, a query that is run on a lightly-loaded ISA Server computer may not cause this problem. However, if the same query is run on a heavily-loaded ISA Server computer, the problem may consistently occur.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

To run a query on the ISA Server log files, follow these steps:

1. In the ISA Server Management snap-in, click the ISA Server computer, and then click Monitoring.
2. Click the Logging tab.
3. In the Task pane, click the Tasks tab, and then click Edit Filter.
4. In the Edit Filter dialog box, specify the criteria to filter the data, and then click Start Query.
