Hello Arjan
I have got to reproduce issue running DP inet under domain user.
[Critical] From: OB2BAR_POSTGRES_BAR@juliana.dpteam.com "DPIDB" Time: 16/07/2013 12:43:40
Error while running the PSQL script
Debug.log file showed following error:
16/07/2013 12:43:40 OB2BAR_POSTGRES_BAR.12080.1660 ["/lib/cmn/win32exe.c $Rev: 35470 $ $Date:: 2013-01-14 17:58:40":451] A.08.00 b596
[CmnCreateProcess]: CreateProcessW failed: [1314] A required privilege is not held by the client.
Running DP inet under local system account backup works fine, Do you have something similar in your debug.log file?
Could you please check it looking for any entry at the same time frame that wen error happen?
