Re: IIS 6.0 -> Server.CreateObject of ('null') !

So the rule of thumb that's been around for a few years (use
Server.CreateObject in lieu of just CreateObject) is the other way around in
IIS 6?

I had the same problem originally described (web server would occasionally
go into a state of throwing ASP 0117 and ASP 0241 errors when certain apps
would run 'set conn = Server.CreateObject("ADODB.Connection")'). This
started happening only after migrating a web server from W2k to W2k3. To fix
the problem I changed IIS6 to run in IIS 5 Isolation Mode insead of using
Application Pools and worker processes. I sacrifice a lot to do this, but
I've gotta go with what works. I suspect it could have been an access issue.
 The application pools were running in the context of the Network Service
(the default), not the IWAM account.

I've run into similar conflicts when using application pools with more than
1 worker process (not the case in this instance). My own rule of thumb: If
it's legacy asp, only run it in an App Pool with 1 worker process otherwise
you will run into intermittent problems.

My experience thus far: Much easier to deal with IIS 5.x than IIS 6. I
guess it is understandable in a sense, but still unfortunate.
