Hello, I'm currently running samba 2.2.1a on a redhat 7.1 server. I am consistently having network timeout issues on my clients that are running quickbooks and act. When running quickbooks, they get error msgs stating that they have lost connection with COMPANYNAME.QBW file, file will be reset to last known transaction. I'm convinced this has something to do with oplocks but I'm just not sure. Anyone out there familiar with quickbooks on samba? All the clients are NT Workstation 4.0. Thanks, Jason Norred Norred Technical Services
