Setting up DCOM can be difficult and frustrating. Make sure you kill the TSAutoMgr.exe process after changing settings. Here are my recommendations for configuring computers to share synchronization objects.
1. Windows Firewall Settings. You must either disable the firewall on both computers or add the following exceptions:
- On the computer that created the queue: Add a Program exception for the TSAutoMgr.exe application.
- On the computers that use the queue remotely: Add a Program exception for the user interface application you are using (e.g. SeqEdit.exe)
- On all computers add a Port exception for DCOM (TCP Port 135).
2. DCOM Settings. On the computer that creates the queue use dcomcnfg to make the following settings.
- Computer-wide settings: On the COM Security tab of My Computer, use Edit Limits buttons to grant Remote Launch, Remote Activation and Remote Access permissions to ANONYMOUS LOGON
- Application setting: On the Security tab of the NI TestStand AutoMgr item, grant Remote Launch, Remote Activation and Remote Access permissions to ANONYMOUS LOGON
- Application setting: On the General tab of NI TestStand AutoMgr item, set the Authentication Level to None.
3. Disable COM authentication on your application. If your application on the computer that accesses the remote queue is not called SeqEdit.exe or TestExec.exe, you need this extra step. Add a registry setting that will disable COM authentication for your application (where APPLICATION.EXE is the name of your application, not a path):
[HKEY_CLASSES_ROOT\AppID\APPLICATION.EXE]
"AppID"="{C31FD07F-DEAC-4962-9BBF-092F0F3BFF3C}"
