Error 3027 in windows 7

[Gaharwar]

I installed a management on Windows 7, when I ask to connect to the database midice 3027 Cannot update. Database or object is read-only. I thought it was a sharing problem, but no other users logged into the database refers to me the same error, I also checked the network settings for shared files and find nothing wrong with I really need help to understand how to solve the problem.

The error code 7 may have various origins (physical), including memory, but not only. Try to change your or your strips (you does not mention in your profile, your memory) space, if the error persists, you can also test your memory with Memtest to put on a floppy disk or other medium on which to boot. The test is long enough; one night can help catch errors if any.

I tried to replace the strips with that of my current pc. On another forum, I read this:

The configuration of the computer's BIOS contains incorrect settings or One or more memory modules (RAM) installed on your computer are faulty. I remove and reassembled after cleaning and adding thermal paste. Without success I'm not too keen on going to tinker with the BIOS without help. I think may be a conflict: the list below:

I currently work on the development of two identical database access. On these basis, when are on my C, I have no errors and everything works properly. But when I put it on the network the following error appears: Error 3027: Cannot update, a database or object is read-only. What is most surprising is that today, the first base is no longer an error when I have not changed, But the second base (which is a copy of the first) made the mistake. Although I copied after the first bug is resolved. The error occurs when I make an update on a table. Or from another form, this update happens normally. Moreover, these features existed before I started working on the base and I have not changed. What is the difference between copying and pasting from window to export from Access?
