Could it be possible that there's something wrong with the Temporary
Files?
The error always comes from a file like this:
Error in File C:\DOCUME~1\XXX\LOCALS~1\Temp\CrystalReport1
{8069E57D-6905-4ED5-A130-56876A7AD67A}.rpt:
Unable to connect: incorrect log on parameters. --->
System.Runtime.InteropServices.COMException (0x8004100F): Logon
failed.
I already set the permissions for the "Network Service"-User.
Is there maybe anything wrong with permissions on this folder so that
it can't reload the temporary report?
Thanks for all your help!
