I read the docs on MSDN awhile ago and don't remember any mention of MSDTC. If this material isn't there, can you get this up there?

Ken,

Are you referring to MSDTC documentation in general? If so, you can find it at http://msdn.microsoft.com/library/?url=/library/en-us/cossdk/htm/dtc_toplevel_6vjm.asp?frame=true

re: XP SP2 and Transactions

Ken Cowan — Fri, 25 Jun 2004 18:39:00 GMT

MSDN has a ton of material on XP SP2 changes for both admins and developers. The way they wrote it, their list was everything one needs to know about SP2. Your blog post is important information that (I think) is missing.

I remember seeing the gory details about DCOM and RPC changes. I don't remember seeing anything about MSDTC changing.

XP SP2 , MSDTC & COM+

Thomas Mathews — Fri, 24 Jun 2005 10:30:21 GMT

I have enabled the Network DTC Access and XA Transactions. Modified the Firewall Configuration to exclude MSDTC, still my COM+ components fail to initiate. My machine hosts an Website (on Win XP), uses COM+ components and Oracle 8i Client. If I try to use insert, update or delete functionality, it raises [Microsoft][ODBC driver for Oracle]Failure in DTC: not able to validate open information.

Could some help me out?

re: XP SP2 and Transactions

P Velasquez — Fri, 08 Jul 2005 17:29:59 GMT

I am having the same issue Thomas. I have enabled the Network DTC Access {Allow Remote Clients, Allow Remote Administration, Transaction Manager Communcation -- Allow Inbound, Allow Outbound and No Authentication Required} and Enable XA Transactions on the XP SP2 with DTC Logon Account NT AUTHORITIY. Modified the Firewall Configuration to exclude MSDTC, still my COM+ components fail to initiate. My machine hosts an Website (on Win XP), uses COM+ components and Oracle 9 Client with registry settings of [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI ...OracleXaLib set oraclient9.dll, OracleSqlLib set orasql9.dll, OracleOciLib set oci.dll]. I get [Microsoft][ODBC driver for Oracle]Failure in DTC: not able to validate open information.
I checked the trace file for the DTC and the events appear to be in order - TRANSACTION_BEGN, RM_ENLISTED_IN_TRANSACTION, RM_VOTED_COMMIT, RM_ISSUED_COMMIT, RM_ACKNOWLEDGED_COMMIT.
I am thinking it is the XA DLL I see information suggesting to create a registry key for the "mtxoci.dll" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\XADLL] keyname: mtxoci.dll data:c:\Sindows\system32\mtxoci.dll Would you agree?????

re: XP SP2 and Transactions

P Velasquez — Tue, 12 Jul 2005 18:58:20 GMT

SOLUTION...[Microsoft][ODBC driver for Oracle]Failure in DTC: not able to validate open information.
I added the key as I mentioned above and it works. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\XALL]
The error only happens when in the VB6 app the MTSTransactionMode is set to 2.

Problem still there!

I have done exactly as mentioned by you and the error message still says the transcation manager is disabled. I am using windows xp professional sp 2.
I have also turn my firewall off and exclud the msdtc.exe.
My application is running .net 1.1 with com+ iis authentication set to windows integrated. IE is set to prompt for password and uid. Domain userid is entered when running the pages.

Any idea??!!!

Where do you see this error message? If you do a "net stop msdtc" and then a "net start msdtc" do you any entry created in Event Viewer (Application and System)? I also recommend posting your issue at our transactions forum at http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=388&SiteID=1 for a faster response. Thanks.

This information is very good. I have used it to resolve cloned server issue (windows 2003 servers). Right now I am facing an issue with windows XP SP2 machine calling a database server (windows 2003 server). The error is the usual "New transaction cannot enlist in specified transaction coordinator" and "Error 8004d00a. Distributed Transaction error" I have tried diagnozing with DTCPing.exe as suggested; I am getting the following error with DTCPing; The error is: Problem:fail to invoke remote RPC method Error(0x5) at dtcping.cpp @303 -->RPC pinging exception -->5(Access is denied.) RPC test failed The error I am getting is when windows 2003 server tries the DTCPing to communicate with XP SP2 machine; although the communication from XP SP2 to windows 2003 server is successful. I have tried the solutions suggested, 1) The correct security configuration for MSDTC on both machines(No Authentication Rquired) 2) Adding MSDTC.exe as an exception in the windows firewall 3) RestrictRemoteClients key: this key is not present in my registry although I am running windows XP service pack2 machine. Can you help me with this error?

I want help of you guys in solving an issue related to MSDTC. I am developing a multiuser DB application with MS SQL Server 2005 and .Net 2005. Both my DB Server and client machine are having XP Prof. with SP2.

I am using System.Transactions to maintain Distributed Transactions. I do not face any problems when I execute my code on the DB server itself. But when I try to execute the same code from any client machine, the following error is fired : "Communication with the underlying transaction manager has failed."

I am really stuck because of this issue. Its a blocker for me.

I have also made the following configuration on my system :

1.MSDTC on both Server and Client :

a.Network DTC Access - Checked

b.Allow Remote clients - checked

c.Allow inbound and Allow outbound - checked

d.Mutual authentication required - selected

2.Added the following keys in the registry:

a. HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\RPC - EnableAuthEpResolution 1

b. HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\RPC - RestrictRemoteClients 0

3. I have disabled the firewall and also added msdtc.exe in the exceptions.

please help me....
