We have a handfull of Sybase PowerBuilder 8.0 applications that connect to our MS/SQL Server. They worked fine with MS/SQL 2000 but since upgrading to MS/SQL 2008 R2 we're having problems. On my workstation, the developer workstation, the compiled image runs fine. On other workstations however the image times out with an error about being unable to connect. Things like Excel sheets and Crystal Reports that are linked to the database work just fine. I've looked at installed components ( SQL Server 2008 native Client ) and don't spot anything that might be missing. If I log onto a user workstation with my user id and pwd the applications still do not run.
Any idea where I should look?
