I have an application that reads/writes from/to message queues on remote application servers. The clients usually run on machines outside of the servers' domains/forests with no trust setup.
In Windows XP this was no problem, but with the introduction of Windows 7 it stopped working.
After some research I found the suggested Registry tweak for the server (the NewRemoteReadServerAllowNoneSecurityClient DWORD in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters\Security fix) and implemented that, but the software still throws an exception that access was denied to the Message Queuing system.
The message queuing system on our test server is wide open, with full control for both the EVERYONE and ANONYMOUS LOGIN accounts.
What am I missing?
I've been dealing with Microsoft support for a little over a week and they have confirmed that this is a bug in Windows 7 and in Windows Server 2008. I'll come back and add more details about when they expect a fix or workaround when I have that information, but for the time-being it appears that this is simply a bug and unworkable.
