I'm doing more research into this problem and it only seems to be present in Windows 7 systems. Our Service component is written in C++ and uses the IBPP Library to connect to the database. The UI is in Python (2.6 currently) and uses kinterbasdb.

On Windows XP Systems everything works. Both processes have an active connection.

On Windows 7 systems I can launch multiple instances of the UI and they function properly, but I can't run both the UI and the Service. If any UI instances are running the Service will not start (cannot attach to the database). If the Service is running I can't launch the UI. That seemingly indicates that the Service is requesting an exclusive handle somehow, but I can verify via NetStat that the connection the Service is making is going through the Firebird Service.

Any input or advice is greatly appreciated,
