Enable msdtc on windows server 2008

Andrew Peters Andrew Peters Thanks for the comment about the error being caused by creating multiple connections within a single TransactionScope. I was getting the error and that was exactly the problem. I'm on windows 7 and 8, and there's only a "Default Coordinator" section.

Where can I get to the security configuration that you're talking about? At the client: fill in the server netbios computer name and try to setup a DTC connection I've had my fare deal of problems in our old company network, and I've got a few tips: if you get the error message "Gethostbyname failed" it means the computer can not find the other computer by its netbios name.

The server could for instance resolve and ping the client, but that works on a DNS level. Not on a netbios lookup level. You should compare the security tab for the msdtc and get the server and client to match. One other thing to look at is the RestrictRemoteClients value. Depending on your OS version and more importantly the Service Pack, this value can be different.

Other connection problems: The firewall between the server and the client must allow communication over port And more importantly the connection can be initiated from both sites I had a lot of problems with the firewall people in my company because they assumed only the server would open an connection on to that port The protocol returns a random port to connect to for the real transaction communication.

Firewall people don't like that, they like to restrict the ports to a certain range. You can restrict the RPC dynamic port generation to a certain range using the keys as described in How to configure RPC dynamic port allocation to work with firewalls.

Dan, Do I not need msdtc enabled for transactions to work? Do I not need msdtc enabled for transactions to work? Either way, multiple connections are not being made as far as I'm aware. I've already run those steps on the client PC, are you saying I should also do those steps on the database server? Dan, you are not required to enable DTC if you are using ado.

The menus look different in Windows Server so I'm not sure if everything applies. For example, the registry key to allow RPC calls does not currently appear in the hive listed in the article. NET services. Checked everything that said "transaction, COM, or. I could not set the Rights Management in gpedit.

I am logged in as administrator and administrator was listed, so I don't think it's an issue. Any ideas? My windows firewall currently shows DTC as unblocked for inbound and outbound connections. Are they performed on the app only, or the app and component? Did you set up roles for your app, and populate with your logon user?

Did you enable the role for your component? If you're going to use this component cross-machine, the user will need to be a member of the "Distributed COM Users" group. There's a couple of things wrong. Local System is anonymous off-box. I'd drop the NT service and use a configured user or interactive for now. The other thing is that you ask for app and component security. That means you need to add yourself to an application role for the app and to enable your component for that role.

This is exactly what your catalog error message is telling you. It does not matter if you are domain admin. Please refer to role-based security in MSDN for further info. If you want a transaction, you better mark the component or Transfer call as "Transaction Required", or you could withdraw the money without depositing it.

I also don't know how AutoComplete works without a transaction. I'm not making any reference to Active Directory. If you open the Component Services snap-in comexp. The first node is the App-level.

Inside the app are three nodes: Component, Legacy Components and Roles. Inside Components are interfaces and then methods. When you right-click a component and look at properties, there are five tabs, including those for security and transactions. Under the security tab, you can control access by roles.

Also, please consider using a domain user rather than Admin, if you're going to use these components in a distrubted fashion. I'm glad that things are working now.
