Issue/Introduction

You are trying to edit one of your pre-existing preboots. For example, it is called "ITMS_WinPE10".

When you are trying to view / edit the details of your Preboot Configuration through the following menu option:

Settings > Deployment > Manage Preboot Configurations > Policy Rules / Actions section> <Select a preboot configuration and click Edit>

You see the following:

Altiris Notification Server Error
The following error occurred on the page 'PrebootConfigEditor.aspx':
Unknown or unspecified error:
More details can be found in the Altiris Notification Server Log.

In the NS log, the following Error event is present:

ITMS 8.x

DS 8.x

Cause

Invalid UseiPXE tag in the preboot configuration XML.

The NS log says that the page is expecting some sort of value:

String was not recognized as a valid Boolean.

While reviewing the XML for this preboot configuration, it was found that there was a missing portion at the end for UseiPXE tag:

<item>
<PrebootImageConfiguration>
<name>ITMS_WinPE10</name>
<description />
<OperatingSystem>
<actionType>0</actionType>
<ostype>8</ostype>
<Architectures>
<X86>False</X86>
<X64>True</X64>
<IA64>False</IA64>
<Archtype>2</Archtype>
</Architectures>
</OperatingSystem>
<oem>DS Agent</oem>
<automationtype>2</automationtype>
<AutomationFolder>False</AutomationFolder>
<PXE>False</PXE>
<BothPreboot>True</BothPreboot>
<PrebootType>2</PrebootType>
<RecreateTimeStamp>2020-10-22T00:23:01.4061196Z</RecreateTimeStamp>
<IsLockKeyboardMouse>false</IsLockKeyboardMouse>
<UseiPXE />
</PrebootImageConfiguration>
</item>

so, if you create a new one and compare them, the new working one should look like this:

<item>
<PrebootImageConfiguration>
<name>ITMS85RU4New</name>
<description />
<OperatingSystem>
<actionType>1</actionType>
<ostype>8</ostype>
<Architectures>
<X86>False</X86>
<X64>True</X64>
<IA64>False</IA64>
<Archtype>2</Archtype>
</Architectures>
</OperatingSystem>
<oem>DS Agent</oem>
<automationtype>2</automationtype>
<AutomationFolder>False</AutomationFolder>
<PXE>False</PXE>
<BothPreboot>True</BothPreboot>
<PrebootType>2</PrebootType>
<RecreateTimeStamp>2020-10-22T17:50:15.2766562Z</RecreateTimeStamp>
<IsLockKeyboardMouse>False</IsLockKeyboardMouse>
<UseiPXE>True</UseiPXE>
</PrebootImageConfiguration>
</item>

So, the "PrebootConfigEditor.aspx" page is expecting a NULL, False or True value to be passed.

Resolution

  1. Check under "Automation_Image_Configuration" table and see if all the preboot configurations that you have either has a NULL, False, or True entry under the "UseiPXE" column:

    select * from Automation_Image_Configuration

  2. So if you compare the bad with the working one, it is what the table may have:

    select * from Automation_Image_Configuration
    where itemguid in (
    '797AC522-E3DD-454E-8D29-BB9CC2EBCCC5', --bad preboot
    '35AFFB22-5CF6-430B-9B79-C258C413365A' --good preboot
    )


    Configuration_Name ItemGuid OS_Type Processor_Type Description OEM_Extension_List Has_Been_Created Automation_Type ActionType IsLockKeyboardMouse UseiPXE
    ITMS_WinPE10 797AC522-E3DD-454E-8D29-BB9CC2EBCCC5 8 2   DS Agent 0 2 0 FALSE  
    ITMS85RU4New 35AFFB22-5CF6-430B-9B79-C258C413365A 8 2   DS Agent 0 2 1 FALSE TRUE

    As you can see, the bad one doesn't have an entry under "UseiPXE". This is causing the boolean check failure for this "PrebootConfigEditor.aspx" page.

  3. In order to modify that column, use the following query (so you can update the "Item" table and fix the XML for the bad preboot configuration):

    update item
    set state = replace (cast (state as nvarchar (max)), '<UseiPXE />', '<UseiPXE>False</UseiPXE>')
    where Guid ='797ac522-e3dd-454e-8d29-bb9cc2ebccc5' --GUID of the broken preboot configuration
