Thanks guys/gals! Any help will be greatly appreciated!

It's looks like that your IIS is running correctly. For me, the main problem is access rights with SQL Server on your SSRS instance. Check also the Errors logs for SQL Server with SSRS.

I will check into the logs for SQL Server

Hello RobGarrison87, Reporting Services SP1 and earlier do not run on Windows Vista. If you try to run an SP1 report server on Windows Vista, you will encounter the error. The error will no longer occur after you apply SP2 or upgrade to SQL Server 2008 and configure the report server for operation. Here are some articles about this issue for your reference, please see: Troubleshooting Server and Database Connection Problems: http://msdn.microsoft.com/en-us/library/ms156468(v=sql.100).aspx http://social.technet.microsoft.com/Forums/en-US/sqlreportingservices/thread/47697d43-e8f9-4c5f-8354-4d848d46e26b Regards, Bin LongBin Long TechNet Community Support
