I'm trying to run an application remotely. The host has Windows 2000 and .NET Framework 2.0 installed. We also have SQL Server Express running on XP. When I try to execute the program I get this error. It run's fine on my development computer and on the computer running SQL Server Express. Any ideas why this might be happening? 

UnauthorizedAccessException
