Communication with the underlying transaction manager has failed

[Stefan]

Hi!

I´ve an appplication which uses transcation in com+ to communicate with an
remote sql server database.
This works fine on my windows 7 x86 "appserver", but on another station
using Windows 7 x64 it fails with the message below. I don´t now if
it has something to do with x86, x64.

When saving to the database I got:

System.Transactions.TransactionManagerCommunicationException was unhandled
by user code

Hi!

I´ve an appplication which uses transcation in com+ to communicate with an
remote sql server database.

The Web server and SQL server must have MSDTC enabled on both servers and
both machines must be using the same MSDTC cridentials.

Thanks for the reply.

Both machines have msstc enabled and uses the NetworkService-account.

Thanks for the reply.

Both machines have msstc enabled and uses the NetworkService-account.

Hi,

In both the MS DTC Settings, make sure Mutual Authentication is
selected and also windows firewall should be disabled.

Once this is done, Stop and Start MSDTC.

Ram
