Hi I found a solution for this :
-start the modifiablesrd.exe from a client machine c:\program files\symantec\backup Exec System recovery\Agent
- Be sure you click Custom on the driver comparison window
- add the drivers you need
- Be sure you provide a short lable name and short iso file and save it to the default location (c:\documents and settings\%username%\my Documents and finish.
Problems i had before was the location where i writed the iso to (c:\temp) and the label name (to long so i provided a label name eg. CUSTOMSRD)
Best regards,
Bert
