The problem is solved by the help of this http://www.adopenstatic.com/experiments/ConnStringSpeed.asp
On the global.asa the directory of the access file (.mdb) was pointed on the wrong directory
Application ("APSConnStr") = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Inetpub\wwwroot\AmStaffing\App_Data\APS.mdb;Persist Security Info=False"
which is suppose to be
Application ("APSConnStr") = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\inetpub\wwwroot\App_Data\APS.mdb;Persist Security Info=False"
