My problem is that I get following error :

Microsoft JET Database Engine (0x80004005)
Unspecified error
/dtk/common.asp, line 24

when running my ASP – Access Database on my localhost.

My script is following:
Dim dcnDB 'As ADODB.Connection
Set dcnDB = Server.CreateObject("ADODB.Connection")
dcnDB.ConnectionString = _
"Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Persist Security Info = False;Data Source=" _
& Server.MapPath("Master.mdb")
dcnDB.Open
Set OpenDatabase = dcnDB
The error occours when calling dcnDB.Open
Everything has been working. It just stopped, the next day I turned my PC on. Then I checked the security settings on the folder containing the database and ASP pages. Temp folders (%tmp%, %temp). The IUSR_PCName and IWAM_PCName has full access to these folders. When searching the internet for this error – all answers is the permission to access the temp and other folders. But the permissions is OK according to the security tap.
The script is working fine on the webhotel.
I am running Windows XP – servicepack 3 and all other updates.

Why did it stop working????

Any ideas???

Now hold on a minute here. You're running your entire website out of a temp folder?

What is a webhotel?

Nope - not running the entire website from a tempfolder. But when running the website on the localhost/127.0.0.1 the database uses the temp folder for temporaly files. And that why the IIS needs access

A webhotel is a ISP.

So - running the website from my ISP - works great. But running i local - not works great.

What does
return?

The server.mapPath returns:

C:\Inetpub\wwwroot\DTK\Master.mdb.

And that is where the database and asp files are located in local folder.

What does all this have to do with temp folders?

Hi Teddy.

<-What does all this have to do with temp folders?->

Actual nothing. But all hits, when searching for this error, describes how to check and add the permission for the IIS to access temp folders. But this is not actual my problem. The IIS has fully access.

But when I run my webside local on my computer - this error occours. But if it not related to above - then - what cause the error?

So - has somebody seen this error related to something else??

You need to grant file permissions on the files your website wants to use.

Hi Teddy.

I have granted access all temp and local web folders, with iusr_pcname and iwam_pcname with full control.

And I had actually everything running perfect. The data from access database where shown on the webpages. But one day it stopped working. The error code where shown when it tried to open the database. Then start check and check the permissions on the folders. These is intact. So if - permissions is intact - what is then the problem???

Have you setup iis to write to folder where the mdb is.

Hi Myle.
Yes I have. I had worked before. After turning the PC on next day, it stopped working????

Then clearly something changed.

Throw all of your assumptions about how the environment is configured out the window. Re-confirm everything.

Can you open the database interactively? Perhaps it has become corrupt or locked in some way.

If everything working one day and not the next you need to have a look at what changed...

Was there a service pack installed on your machine via SMS or something similar?
