Well this is a fun one. One of the web apps on our server has suddenly started throwing an error

IndexOutOfRangeException: Index was outside the bounds of the array.]
   WebServiceDeskPortalAdmin.MainPage.Page_Load(Object sender, EventArgs e) in C:\projects\WebServiceDeskPortalAdmin\WebServiceDeskPortalAdmin\MainPage.aspx.cs:0

Running the code locally displays no such error and runs as designed.

My thought is something amiss in the IIS setup but being a mere developer my IIs skills are sorely lacking and Our web/network admin training education consists of stackoverflow lurking.

the only other thing that might be at issues is that we are using CA Siteminder for user auth. but again there is no one here with any real training in that package.

The other app on this server works just the way it is supposed to.

The other odd thing is the file it is pointing to is the one on my local machine where the app is built and published before being copied to the server.

What I have tried:

I have tried starting and stopping the server. I have also compared the web config to the web config on another box running the same app and found no differences

Did you recently edit a javascript file?

There is no javascript in the app.

Well being a lazy guy I never looked at my log files because the error was said to happen on line 0 and we all know there is no line 0 in source code. However I went and looked just be able to tell OldGriff his advice was bogus. Turns out the crash was several lines into the app and caused by me breaking on of my own rules and reusing a variable and then attempting to manipulate that variable with the assumption it still had the value from the first assignment (doing string split) I am a bad boy

Because it's published to the server as a compiled file, and that applies optimizations and so forth which removes line numbers?

Because you probably can't debug "live code", you need to add logging to you app to try and narrow down exactly which arry and which index is involved. Given that it's probably also related to your data, we really can't do that for you!
