@Wayne Schulz said. The IT admin may need to create a new VDI image if they use VDI and you think it's happening when they logon. When you create a Silent Connect DSN (and generally System DSN is better idea than User DSN), it creates a registry entry which when it's working the 3 credential values are populated correctly. Here's the location in regedit:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBC.INI (this is for normal 32-bit o/s)
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI (this is for 64-bit o/s)
My DSN is called SILENTMAS90 so I browse down to the SILENTMAS90 subkey under \ODBC.INI. You do the equivalent. Then notice UID, PWD, and Company values. They'll be blank when not working. Tell the IT guy/gal something is overwriting that, making it not persist. If you can duplicate the issue by logging off of Windows and logging back on again, that will be helpful for them. It could be the particular user needs to be moved to a different domain group. If they use VDIs then likely the VDI image needs to be refreshed.
