When you click the "validate" button, does it come back successful? Also, show the MSDTC configuration you've set on your SQL box.
It doesn't matter if it's the "most optimal", it's required for vRA to function. If you don't enable and set DTC according to the documentation, installation and configuration will fail.
You're right, and as you say according to the documentation is the optimal solution. Here is the links SQL Server Configuration for vRealize Automation & Configure Network Access for Distributed Transaction Coordinator
Thanks for the recommendation, Best Regards RA.
I'm installing vRA 7.6 with vRLCM....
This one, solve my issue with "Install IaaS web" step.
The errors I get were:
Result: (10032)The MS DTC on the IaaS database server is not configured correctly for network access.
If the servers that host MSDTC have been cloned their CID might not be unique(located in HKEY_CLASSES_ROOT / CID)thus causing this issue.
To regenerate its CID values the MSDTC must be reinstalled.
Result: (10033) The local MS DTC or the one on the IaaS database server (if the database is external) is not configured correctly for network access.
If the servers that host MSDTC have been cloned their CID might not be unique (located in HKEY_CLASSES_ROOT/CID) thus causing this issue. To regenerate its CID values the MSDTC must be reinstalled.
Details: Communication with the underlying transaction manager has failed.
Details: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems.
Possible causes are:
a firewall is present and it doesn't have an exception for the MSDTC process,
the two machines cannot find each other by their NetBIOS names,
or the support for network transactions is not enabled for one of the two transaction managers.
(Exception from HRESULT: 0x8004D02B)
This fix applied in both servers, IaaS and SQL, fixed my issues.
Thanks for the post
