SQL Server is designed to grab as much as memory it can, as memory is
good for cache. The assumption is that SQL Server runs on a dedicated
machine. If some other app needs memory, SQL Server will yield, but may
not always yield timely.

You can use Enterprise Manager to configure SQL Server to not use more
than a certain amount of memory. This appears to be a good idea in your
case.

Whether it is really a bright idea of running IIS and SQL Server on the
same box is another issue.
