Netbios issue

I seem to be having a Netbios issue. Here’s the problem: We have an access database on our main file server named NEWSVR. This server replaced the old file server named OLDSVR. When going to access this particular database, even though I manually navigate to the file, which is on NEWSVR, I get an error message saying:

\\OLDSVR\Contact.mdb is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

Whenever I go to access the database file, Access keeps looking to the old path. How do I implement the new path to the database file?
