Users Cannot Access Secure Database
Jun 2, 2015
This morning I accidently ran the "User-Level security wizard" on a secure database that we use. I meant to add a member but clicked the wrong thing and followed suite by hitting "Finish" instead of cancel because I wasn't paying attention. Aside from creating a "Security.mdw" file which isn't being used at all, it also somehow managed to lock everyone but the administrator out.
I checked the Users/Groups and Permissions, they are all there and correct, nothing seems to have been changed at all but when anyone tries to log in now they get the following error:"You do not have the necessary permissions to use the '...mdb' object. Have your system administrator or the person who created this object establish the appropriate permissions for you."
I've read some posts with similarish issues that recommended recreating the .mdw file and importing the data over. The file is encrypted so I wasn't able to do that but I did try making a copy and renaming it then changing the path in the Access shortcut to the copy instead. What all files/settings handle this and if the Users/Groups show up correctly in the database, what could be preventing the users from getting in?

I am kinda new to 2007 and have at the moment a simple database.
I want three things
A: Use the database on a server.
B: Restrict the use to users etc as i used to be a ble to do in Access 97 i think (do i have to make a MDW if so how ?) 9I tried ACCDE but does not seem to do anything)
C: When users use the datavase not see all the normal access editing stuf..

I would like to secure my database (ha ha...at least to some extent).
Here is the basics...
When someone comes into the database I can identify them as they enter by using "Environ("username"), this gives me a unique number for that user ("R54436") (I am on a system called "Citrix" with FE/BE) and from there I would like to:
1.) let them in or not let them in
2.) direct them to particular areas based on who they are
3.) deny access to certain areas all together
I have a table in which I have all users "R" number along with name, user level (1,2 or 3) and the branch office number and can add other info if needed.
I have a form that loads before anything else (invisible) that captures the users "R" number.
I guess I am just not sure how to compare the "R" number that I capture on the invisible form with the "R" numbers in my table. Ultimately once I find a match I would like to populate the invisible form with that users values from the table so I can reference those values throughout their vistit.
Any pointers would be great.

How do I secure my database so no one can install it on other computer
I know I can make the MDE file, but any one can use it.. is there a way to create a installation setup so it needs a serial o something like that.. if so what do I have to do?
I don't want my database to be installed unless I provide the authorization

My program is finally complete, much thanks to everyone here that helped me!
Here's (hopefully) my final issue:
I haven't actually tested this yet to see if it's an actual issue, but I assume it might be. The program i just built needs to be transferred to my client's computer. currently my program consists of three files: PROGRAM.mdb (interface), DATA.mdb (linked tables), PROGRAM.mdw (security file). they are in their own separate folder (C:Program) and play nicely together. i'm concerned because i think that once i zip it up and email it over, when my client unzips it into a folder on his hard drive (named c:program so he doesn't have to re-link them), it might not work because of the .mdw file. if anyone recalls my thread entitled "H E L P ! ! ! !" you see why I'm concerned.
should this just run without a problem, or do i need to have him do all sorts of steps to reassemble the program?
usual lifesavers? i love you guys
Thanks

I just post this one because it took me more than an hour to find a comfortable solution for access 2003
http://support.microsoft.com/default.aspx?scid=kb;en-us;826765
To set the AllowBypassKey property to False, follow these steps: 1. Start Access.
2. Open an Access database project.
3. In the Database window, point to Macro on the Tools menu, and then click Visual Basic Editor.
4. In the Visual Basic Editor, click Immediate Window on the View menu.
5. Type the following code or paste the following code in the Immediate window, and then press ENTER.CurrentProject.Properties.Add "AllowBypassKey", False
6. Close the Visual Basic Editor, and then close the Access database project.
7. Open the Access database project. Try to bypass the startup options that are set for the Access database project by holding down the SHIFT key while you open the Access database project.
The functionality of the SHIFT key that permits you to bypass the startup option is disabled. Although you hold down the SHIFT key to bypass the startup options, the startup options are executed. You cannot bypass the startup options.

I've made an access project (ade) and stored the admin with password in the ade file.
When I open a new database I can use the import feature to import all tables with definitions and data from the ade file. All other objects are being locked.
How can i disallow tables from my mde to be imported into another access application?

I am about to allow users to access a database I redesigned for others to use.I am trying to save it as an ACCDE so they can't mess it up. The database is very very simple.6 tables each with only 4 fields or less... and none are related to one another
7 forms.
1 report.
0 queries... it's just a SKU generator.
When I attempt to save as ACCDE I get an error that reads."Microsoft Access was unable to create the .accde, .mde, or .ade file.This error is usually associated with compiling a large database into an MDE file.* Because of the method used to compile the database, a considerable number of TableID references are created for each table.* The Access database engine can only create a maximum of 2048 open TableIDs at one time.* Exporting a database as an MDE potentially can exceed this limit if the database has a large number of objects (table, macro, form, report, etc).
There is no accurate method to estimate the number of TableIDs the Access database engine uses during the process of compiling a database as an MDE.* However, each VBA module and each form uses one TableID, as a result, if the database has 500 forms, and each form's HasModule property is set to Yes, as many as 1,000 TableIDs are used."

Hi, I created a database where everybody should insert his holiday plans and absence of business. the Database is linked and opens automatically the form when you click on the link on the pdf. But know it is not possible anymore that more than one person opens the file to insert the data. The mistake is: Could not lock file!
What do I have to do that more people can use the database at the same time (not only read-only) Thank you for the help

Greetings. When I create an Access database on my company's "secure" server (through a PIX box), I get this message in a dialog box when I try to open the database again: "Open File - Security Warning. Do you want to open this file?" It then gives the file Name, Publisher (unknown publisher), Type (Microsoft Office Access Application), and From (the file path and name). The bottom of the dialog box has this message: "While files from the Internet can be useful, this file type can potentially harm your computer. If you do not trust the source, do not open this software." When I click on the "Open" command button, the file opens just fine.
There are a couple of things going on here:
1) When I open this same database or any other Access database on another of my company's servers that is not protected by a PIX box, I do not get this dialog box.
2) When two users try to access an MS Access database on the "secure" server, the first user will get in, but the second user will not. The second user will not get ANY warning messages -- nothing happens. This occurs if the second user tries to open the database by either double-clicking on a shortcut on the desktop or by double-clicking on the file name in Windows Explorer. Note that the second user CAN access the same file if s/he starts up MS Access from scratch, and then chooses FILE>OPEN from the main menu.
My goal is to be able to let multiple users access the MS Access databases on the secure server by either double-clicking on the shortcut icon or by double-clicking on the file name in Windows Explorer.
I thought perhaps that the "unknown publisher" issue might be part of the problem on the secure server. So I created a certificate using the utility "SELFCERT", went into the database, went into Visual Basic (Ctrl-G), went into TOOLS>DIGITAL SIGNATURE and assigned the digital signature, and re-saved the file. I then exited the file, went back in, and the dialog box still pops up saying the file's publisher is "unknown publisher"! If I go back into Visual Basic, the database is clearly marked as digitially signed by me. I don't know why the initial dialog box is still showing that the file is not digitally signed.
If anyone has any thoughts about these issues (multiple users not being able to access the same Access database, and why my file is saying it is still not digitally signed), I would appreciate your input. FYI, I am on a Windows XP workstation and our company users Windows Servers.
Thanks,
David

I am using Access 2007. My boss has given me a project to create a tool for our team. I'm done with most part of the project, but for the last part I want editing and updating of database restricted to a few members of our team. However others can access the database and run queries etc. through buttons on a form.
I went about creating a login form for users to get access to the database and in turn created a table with fields UserID, UserName, UserPW and a yes/no field titled IsAdmin. For those who would be limited access would log in as 'Other' user and same as password. I am then using the code to determine if the user should be treated as admin or not by looking up the IsAdmin field in the table. Following is what I have so far, but it needs correction some places and I can't figure where:
Private Sub cmdLogin_Click()
Dim xxAdmin As String
'Check to see if data is entered into the UserName combo box
If IsNull(Me.cboUser) Or Me.cboUser = "" Then
MsgBox "You must enter a User Name.", vbOKOnly, "Required Data"
[Code] ....

I created an access database for the sole purpose of sharing approved data with my entire company. The end users will view the data in a Form which utilizes several tabs and also gives them the ability to run pre-set queries out of the Form. The Form was created using several queries which were built from tables off of the server.
The tables update every day, as does the information in my Form. The problem I am running into is that it takes about 2 minutes to open the DB (the DB opens directly to the form and all queries run immediately to update), which is annoying to end users and might deter them from actually using the tool. I have tried moving the DB to SharePoint, but that did not work due to the size of many of the tables.

I am the administrator for a 2010 Access Client Database that consists of many clients with their information and we have three users whom go in and edit-add information to this Database and it hasn't been a problem until two users have tried to edit the same client record at the same time and then we have had some issues...
So, not sure this is even possible, but can one prevent more than one user being on the same client record? Is there a way to have a message come and say this record is in use?

I have Access 2003 in my computer and I have developed an application which I want to share with my co-workers. But they have only Access 2000. Since MDE is only in 2003, I had to convert my 2003 application to 2000. Is there a way to secure 2000 application? I dont want anyone to change my code or import or read my code..I am not sure what is possible..Could someone please tell me how I can do that?
Thanks.

How to secure SQL data when my MS Access database must access it using linked tables. Generally speaking on the Internet, assertions that migrating to SQL is more "secure" are rampant; explanations of just how that is are scarce.
Sure I can restrict access and put different roles on different tables, then put different people in those roles, but that doesn't really do me any good. Ultimately I want to achieve the following: Allow them to do all kinds of stuff (including Update, Delete, Insert) using my access application, but I would NOT want them to have those same rights if they installed SQL Server Management Studio, or for that matter, simply created an ODBC connection using another access or excel application.
In other words, ideally, I'd like to have SQL server view my Access application as a user in its own right. Not sure if that type of impersonation or identity is possible to achieve.

I have designed a database which I intend to split for multi-users to access from one front end icon on a shared folder at work. I have designed a form bound to cmr record table and on it a subform to another table where cmrs activities will be saved. The form has buttons to and blank controls.
User can create a new activity entry by typing into the blank controls and pressing the save button which saves to the activity table. the edit button extracts a selected records details (selected on the subform) from the activity table and populates the blank field for a user to edit and then hit save to save changes. The delete button deletes a selected record from the activity table. I intend to have multi-users either accessing, viewing and a possibly editing the same customer at the same time. The simultaneous viewing is essential but the simultaneous editing, though not desired is inevitably going to occur.
What I would like to know is:
1. Can you lock an individual record in a table or does the whole table have to be locked. E.g If Colleague 1 is editing Cmr A's record in Table1 can he lock it so Colleague 2 can view and edit Cmr B's record in Table1
2.Can Colleague 1 access/read Cmr A's record in Table1 to retrieve details toe the form controls if Colleague 2 is viewing or editing Cmr A's record in Table1
3. If record lock is possible, how can I initiate it in my example code below.Edit activity record Code
Code:
Private Sub Edit_A_Click()
'Get Data to text box control
With Me.R_P_Data_P_Subfrm.Form
Me.txtrID = !rID
Me.txtrID.Tag = !rID
Me.txtrefNo = !refNo
Me.cmbrpc = !rPC
[code]....

I have a question about sending secure emails by VBA code in MS-Access. I have a Access application within you also can also send emails by VBA code using outlook. Everything works fine, but now the recipient wants to receive the mails with a digital signature by S/MIME.
I got a digital certificate from the recipient as a pfx-file.
Is this possible in Access using outlook ?
I use MS-Access 2010 en Windows 7

I'm not sure which is the better of two options-
My problem is I need to make it easy for my users by authenticating themselves once when they open the database. User-level security is adequate for that job, but when I need to use the authentication information for connection string, I'm a bit antsy about storing it somewhere in Access, as I understand that passwords shouldn't be stored in the database itself (and as far as I can tell, it's not even encrypted or hashed!)
I am wondering if converting it to MDE would be sufficient to encrypt the password or will it still be apparent using a hex editor? I also know that Jet can try to use its own security to authenicate to the back-end, but not sure what I need to do to prompt Jet to pass along the credentials.
Alternatively, would it be better to somehow implement login using backend's security model, if even possible?
TIA.

I would really like to have a better understanding of the secrurity that comes with access. I would like my DAP to be able to log in with the previleges given for each user. I would also like these previledges to work when someones opens the database with access, however, whenever I set the secureity stuff, copy the database to the fileserver, I can then open it with another computer without any problems. Why is this? Thanks guys, I'n new here.

Is there a way in Access to logout users from a database in order to make updates without having to setup a FE/BE situation? My company is using Novell Client 4.90.0.0 SP1a. I have read some logs where you choose File --> Open (exclusive), but I do not have that option (using Access 2000). Any other thoughts?

Hi Guys
I wonder if anyone could give me some advice on a problem i have with an access database.
I have designed a database and a data input form to collect data that is input by workers, the problem i have is that only one person can enter a record at a time.
I curently use 2 replicated database's on two seperate computers and run the synchronisation once one person has finished so that all the changes are replicated to the 2 different databases
If there is any other easier way to accomplish this i would be very greatful if anybody can shed some light on the subject.
Thanks
Brad
