 Description  « Hide
When FB 3 fbclient.dll connects to a remote FB 2.5 server, it tries to open local (client-side) directories and files.

isql -user sysdba -password masterkey remotehost/3050:D:\Test.FDB

ProcessMonitor run on the client side reveals that isql attempts to read local (client-side) files and directories ("D:\Test.FDB" in this case). The remote connection is then successfully established, but if the client-side drive is a specific type (internal card reader etc.), the affected application may fail with an error message "There Is No Disk in the Drive. Please Insert a Disk into Drive \Device\harddisk1\Dr1".
