Here's an interesting one that has me stumped. I have several ASP.NET
applications writen in VB.NET that stopped posting back on click of a
button. Nothing has changed in the code or the environment, it just stopped
working. Here's my config:

Production:
ASP.NET 1.0
.NET Frameworks 1.1 SP1
Win2K SP4 all hotfixes applied, IIS 5.0

Dev:
ASP.NET 1.0
.NET Frameworks 1.1 SP1
Win2K SP4 all hotfixes applied, IIS 5.0

Compiling workstation:
ASP.NET 1.0
.NET Frameworks 1.1 SP1
WinXP SP2, IIS5.1
VS.NET 2003

If I publish the application to my development environment, it works
fine...publish to production, and nothing happens. Tested with browsers:
IE6.01, IE5.5

My first instinct is to find what changed, but nothing has been done to
either envirnonment since applying SP1 of the framework.

I've tried rebooting, rinstalling the Framework, reapplying SP1, recreating
the application in IIS... no change... I'm out of ideas and the knowledge
base doesn't seem to have anything.

Any ideas?

Here's and interesting twist... it's only the VB apps... C# apps, at the
moment, are behaving.
