assertion task or something like it

I am playing around trying to develop a thing in SSIS that would be like an assertion elsewhere -- e.g., test a precondition and raise an exception if the precondition isn't true. I'm posting this to see if folks have already done something like this or have suggestions how to go about it in a semi-general way that could be re-used.

My toy thingamabob right now has the goal of comparing the grand totals for a numeric field in two xml files and raising an exception if they aren't equal. I've implemented it as two XML tasks, each of which uses XSLT to compute the total and post it as a string into a variable, then a script task to convert the string variables into numbers, compare them, and take appropriate action.

Nothing in the box, and nothing else I have seen. Script tasks and a "debug" variable taht you set yourself would seem to be the obvious method. Perhaps use an environment variable or similar configuration method to set the Debug variable.

ASPNET user with network resources elsewhere on a domain

I've been trying to workout how, without impersonation, I can allow an application running under the default ASPNET user to access a network resource (SQL Server/ADAM) not on the same physical machine.

It seems that because the ASPNET user is a local user not a domain user I can't setup windows authentication on the network resource. That seems to leave impersonation which MS et al say is unwise.

Have I mised something here?

Steve.Yes.

You can change the user running the asp.net process. ONly the STANDARD user is a local user. It CAN also be a domain user, per your choosing.
