Problems connecting to V4 Server

We have a test Server in our office (Windows 2003 server) that we’ve previously been running Navision 2.6 and 3.7 on without any problems. We’ve just uninstalled the previous versions, and installed the client and server for version 4. No errors were reported, but when I try and connect to the server (either using the client on the server or on another workstation) I receive the following error; “The network is not functioning correctly. A ‘packet’ has been corrupted (checksum error). This error indicates that the network is not completely reliable. Please note how often this type of error occurs in the network. Contact your system manager if you need assistence.” Has anyone experienced this or similar. As I say, we only experience this on release 4, I’ve even uninstalled V4 and reinstalled the older versions, which again work ok, only to reinstall V4 and have the same problem. We’re using Net Type of TCP. Thanks for any help.

The server will now by default use a net type TCPSin 4.0. Try changing to that on a client and connecting (or overriding it on the server with the command line). The error you’re getting doesn’t seem to reflect that as the problem, but net errors are often strange.

Hi Robert, Thank you for replying. I have tried doing that but that produces a second error message “The operating system cannot gain access to the file c:[path]\database.fdb. Please check the file type and attributes are correct.” However, the server is logged on with a profile with local administrator rights with full control permission.

Hi Gary, do you start the server process as a service? If yes then the user is not your “local administrator”, since 4.0 the service starts with a user something like “Network Service” (have a look to the task list). You have to give permissions to this user or change the service start (start as user…). have a look here: http://www.mbsonline.org/forum/topic.asp?TOPIC_ID=13001&SearchTerms=Network,4.0 br Josef Metz

I think you’re now successfully connecting - it is just your permissions against the service credentials that are insufficient as Josef says. Network Service has minimal permissions to the local file system. Either grant this account write access to your database folder, or choose another account.

Good morning, and thanks for the replies. I’m not an administrator but I will pass this information onto one of our chaps and ask him to look into it for me. Get back to you all soon Thanks again

Josef, The scenario is exactly as you describe. The service using the “Network Service” user to logon, and this did not have sufficient access. We have changed the logon used and can now connect to the dbf. Thank you very much for all the help Gary
