In 2003 server it works normal.
At first step this message transform info:
"Error: %%17562" (17562 is id of string with castom error description)
And then transform info:
"Error: same error string"
But in Vista and 2008 server this message transform only once.
So, I have message "Error: %%17562" in Event Log.
I have no ideas what I did wrong!
