Navision RTC (sp1) client losing connection

Hi All,

My client has been losing connection from the rtc (it seems to be since we installed nav2009 sp1)

The screen shot below is an example of the error message they receive

When they click ok to the error the rtc closes - they can restart it immediately and it works ok

The error is occuring on some users only at seemingly random intervals suring the day

Any thoughts or suggestions would be greatly appreciated

Thanks

John

Further to my original post the error has occurred several more times but I have found details of the error in the server event log as follows - the problem appears to be that when the user types in something invalid (location in the example below) navision should just give an error message to the user and allow them to continue but in some cases it is closing the users connection and reporting the error in the event log:

Update

We have crearted a scheduled job to restart the RTC service on the navision server every night and this has stopped the problem.

Interesting - 750 views of the post but not one single reply! I wonder what is different about our setup that is causing this problem that no one else is experiencing.

And why have you done so to a services which is running in the background.

Its not problem of NAV its the user who does it first and blames on the system.

Did you read the post before replying?

Hi,

Thanks for posting this… I also seem to get the connection error sometimes when NAV is actually supposed to just error normally: E.g. “Code #### is Invalid”. I’m still trying to find out why this error occurs. I’ll post if I find out why.

Regards,

Vince
