string from MySettings. All is well. This thing works in .NET just dandy.
If I reference this dataset from another project, and load that project
under IIS6/ASP/2003 using COM, it fails with the folowing error on the
FIRST request only:

All subsequent request to this dataset works just fine, so the sql
server IS there, and connecting just dandy.
In this instance above, all the data is doing is returning a single row
using a custom query on the table adapter. The part that throw an
exception the first time is this sequence:
Dim usersAdapter As New MyStuffTableAdapters.UsersTableAdapter
Dim users As MyStuff.UsersDataTable = usersAdapter.GetUserById(userId)
Even if I set the connection manually:
Dim usersAdapter As New MySummitTableAdapters.UsersTableAdapter
usersAdapter.Connection = New Data.SqlClient.SqlConnection(ConfigurationManager. ConnectionStrings("MyStuff").ConnectionString)
Dim users As MySummit.UsersDataTable = usersAdapter.GetUserById(userId)
it still throws the above timeout error on the first request only.
To make matters ever more strange:
Dim usersAdapter As New MyStuffTableAdapters.UsersTableAdapter
Debug.WriteLine(usersAdapter.Connection.Connection String)
Dim users As MyStuff.UsersDataTable = usersAdapter.GetUserById(userId)
The second line there prints the correct connection string, the one used
everywhere else... the same one that works for all request but the
first... so the value IS getting loaded... Of course, as soon as we call
the GetUserById method, we get the connection timeout above.. on the
first request.
Just to reinforce matters, on the first request after unloading all
sites fails with the connection timeout errors above, but an SQL
Profiler trace shows not connection attempt is made at all. For the
second and subsqeuent requests, the dataset queries work just fine, and
the SQL profile trace shows their activity.
At this point, I'm stumped. I don't know what is going on, or how to
prevent the data from crapping out on the first request.
Any ideas?
