ASP.NET process identity does not have read permissions to GAC

[Eric]

I'm trying to run a C# web service that I ported from VS 2003 to VS
2005. I'm unable to run it, I see:

Failed to execute the request because the ASP.NET process identity does
not have read permissions to the global assembly cache. Error:
0x80070005 Access is denied.

In my event logs.

I found http://blog.devstone.com/aaron/archi...2/17/1379.aspx and
tried running:

C:\CACLS c:\windows\assembly /e /t /p
mymachinename\iwam_mymachinename:R

I looked like it ran successfully, but I'm still getting the error
message. I'm pretty sure that iwam is the correct user id, I can
successfully attach to a .NET dll that calls the web service. When I
pull up the list of processes in the .NET ide to attach to it shows
dllhost with that user id, and that's the process that I'm successfully
attaching to and stepping through with my debugger.
