Security Library Failing To Create RC4CryptoServiceProvider Instance

I\'ve been using this for awhile now and it has been flawless. I\'ve moved my development environment from a local Windows 2003 Server to a VM install of Win 2003 Server R2.

I use Visual Studio 2008 and everthing compiles just fine. One of my apps started \"acting up\" so in debugging I noticed that my custom class was throwing an exception when attempting to create an instance of RC4CryptoServiceProvider, e.g.,

RC4CryptoServiceProvider rc4 = new RC4CryptoServiceProvider();

In debugging into the source, the exception is being thrown in CAPIProvider in the CreateInternalHandle() method. I\'m not sure why this would behave differently than when it was running locally.

I hope someone can help as I can\'t seem to get a fix or resolution right now and I\'m stumped. I believe I have the latest library. My assembly version shows

Thank you for any help you can provide.
