We have a client who is running our Delphi app with version 3 – the application runs just fine on XP, Vista & Windows 7 and also on Terminal Server 2003. The client is testing a move to Terminal Server 2008R2 and the gets an immediate crash on application startup – we believe that this occurs when the app is trying to connect to SQL Server (ie the app gets passed all the points up to the connection being opened up). The Windows error is :

It’s puzzling that it works on TS 2003 but not on TS2008R2 and that there is no helpful error message, just the crash!

Any suggestions about how we might get this application up and running on TS2008R2?

Hello,

Please try the following:
- install SDAC (you can download them here: http://www.devart.com/sdac/download.html);
- create a new project and place the TMSConnection component on the form;
- try establishing connection to the server on the Terminal Server 2008R2 computer.

Hi

I've tried using the latest (that I had) dBExpress version - 4.20 and that works OK. We've just upgraded to 4.75 so will try that as well. But it looks as if it's a 'version' issue - would that make sense to you?

I cannot reproduce the problem. Please try testing SDAC as I described in the previous post.

Hi Andrey

The application is now working fine on RDS 2008 R2 with v4.2 or v4.75 - it fails only on v3.10. We can't easily run tests on RDS 2008R2 without visiting the customers site and, as it's now working, it's not viewed as an issue.

Many thanks for your input - if we get any further problems surfacing with RDS 2008R2 we'll set up a test application and use SDAC as you suggest.

Kind regards
Anton

I am happy that this problem doesn't bother you. Feel free to contact us if you have any further questions.
