Re: 4th attempt: UDP Socket Bug
First make sure that the code works and that it is not some other problem,
thus run the code in a normal windows app.
Then make sure your impersonation works. Did you switch anonymous access off
to the virtual directory? Add a test call returning the connecting user
info, thus return
System.Security.Principal.WindowsIdentity.GetCurre nt().Name
and check that it is the expected user.
If it still does not work, then I'm stumped too.

Bryan Martin #2 Re: 4th attempt: UDP Socket Bug
This has all been checked and verified. Again, no problems with TCP. This
does function in windows app as the class will show. Also this same thing
has functioned on IIS prior to SP4 without problems.
I guess I will continue to post every few days until I get some kind of
response from M$ or someone who can point me to supporting documents one way
or the other.

Bryan,
Try posting this question at [url]www.asp.net[/url]. Many of the ASP.NET development
team lurk in there and might be able to point you to something. On a
connected note - have you tried this on a different build spec server
(perhaps one not service packed), or a different runtime to try to eliminate
some of the possible causes.

Thanks for the info and I will try it.
Yes this was function on this server and one other one prior to SP4.
