Running BizTalk 2010 connecting to a Microsoft Dynamics AX 2009 SP1 RU6. For BizTalk we have three AX instances running. The AX configuration files reads:
If the first AX instance fails we have the issue that BizTalk will never start using the other ones.
We just get the error:
Connection with the Application Object Server could not be established.
again and again.
We have contacted Microsoft regarding this issue, and they were not able to replicate the error on a system running Microsoft Dynamics AX 2009 SP1 RU8.
So it seems like the issue has been resolved from RU6 to RU8.
