Hi,

There are some post similar to my problem but that solution are not resolved my error so I post this.

I am using Nav 2009 r2 . I am trying to use RTC for run the reports.But it is not working.

I enter “localhost:7046/DynamicsNAV” after that it shows me my database name but when I click OK.

Then it shows an error message:

---------------------------
Yes No
---------------------------

When I Click YES option it display message.

---------------------------

The connection to the server has been lost. The application will close.

OK

Now ,I trying to open RTC then it showing me same error. Even It is not showing server address window so I can try by changing server address.
