Hi! >Then what changes were done recently, in particular ODBC-related. Same psqlODBC driver 09.00.0101 has worked 10 years. Previously I logged into this server long time ago and then it worked. Windows update history shows lot of updates all called Security Intelligence Update for Microsoft Endpoint Protection - KB 2461484 with different version numbers.
So did the issue show up after the above updates?
What is ntstatus.h? Would looking there for 0xC0000005 give a clue to the problem (and thus solution)?
