Our IT department recently switched us to Windows 7 and an access based enumeration directory structure server. I have not really noticed any difference for most applications. Except MS Access. Since the switch the connection to the server is frequently dropped. What this means is that when you ask Access to do something that requires a form that is not currently active you will get a “network access interrupted” error and the database freezes. To unfreeze the database you have to close it and reopen it. Even with an active form, refreshing it can generate a “network access interrupted” error. Trying to open the VBA editor will get you a “File Not Found” error that you cannot get out of: clicking “Okay” just generates a new “File Not Found” error. You have to crash the database.
Continuing to try to work around these dropped server connections will corrupt your database. I had that happen yesterday. This morning I had to close and reopen my database five times in one hour. And I wasn’t even working very actively with the database.
