I have a Windows Small Business Server 2003 Premium Edition that I keep getting the following error.

Microsoft C++ Runtime Library


A buffer overrun has been detected which has corrupted the program's internal state.  The program cannot safely continue execution and must now be terminated.

I have uninstaalled IIS, restarted, and reinstalled IIS.

Anything else to try?
