Happens only in one company file. other company file hosted on the server do not exhibit this issue. Only way to get control back is to force close QB. Have already ran QB file doctor against the company file, and no errors were detected. See screenshot. Also have ran the QB installation repair utility. Looking through event logs, found "unexpected error 5 in call to NetShareGetInfo" which usually means security permissions issue. These have been verified, and are given at the domain group level to the network share on the file server. (user is able to access via mapped drive and access the QB file to open anyways?) had another user try on a different machine with a different QB username, and they get the same result. QB is not asking for any updates and company file is up to date.
