Workstations have multiple drive mappings to shares on SRV01
. One share has application executables for a network enabled accounting and tax prep program. After a reboot, all mapped drives work properly. The tax prep program can be launched from the share and in some cases will open and function properly until a specific functionality is used. Other workstations will have errors immediately upon opening the application. In either scenario, it is predictable when the error will show up once it has presented previously, and as soon as an error shows up all mapped drives to SRV01
will go offline or inaccessible from the workstation. Then user has to log off or reboot before everything will reconnect. The error messages do usually state something about the drive being inaccessible, but as I mentioned access is fine to all shares (through Windows Explorer, and I've verified permissions) before the error and as soon as the error is thrown all the drives disconnect. This includes shares completely unrelated to the application.
This is an intermittent issue that has been difficult to track down. The vendor of the software denies it's their application of course. I'm looking for confirmation of my conclusion that the application is at fault, or any guidance on what else I can investigate. Thanks!
