I am having difficulty connecting from an asp web site (web server on win2k server) through an automatically established VPN to an Windows 2003 Small business server share into a folder containing the dbf

I get lots of wonderfull errors.  

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC dBase Driver]General error Unable to open registry key 'Temporary (volatile) Jet DSN for process 0x9dc Thread 0x488 DBC 0x38771bc Xbase'.

with the asp coding for above is simply
  Set whConn = CreateObject("ADODB.Connection")
  whConn.Open "Driver={Microsoft dBASE Driver (*.dbf)};" & _
                       "Dbq=f:\testwhdb"

(the f:\testwhdb is the already established VPN network share into the remote machine)



OR errors like

Microsoft JET Database Engine error '80004005'

'\\SERVERNAME\testwhdb\whprods.dbf' 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.

with asp simply
 whconn.open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\boss\testwhdb\whprods.dbf"

OR errors like
Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC dBase Driver]General error Unable to open registry key 'Temporary (volatile) Jet DSN for process 0x9dc Thread 0x880 DBC 0x387bc24 Xbase'.
 
with asp as
 whconn.open "Driver={Microsoft dBASE Driver (*.dbf)};'Dbq=\\boss\testwhdb;"


I am confused

I have looked for things like permissions using IUSR_machine name in the remote machine but still no joy...
The vpn will allow any ports, so nothing is blocked...

Any help would be brilliant

Thanks in advance

Steven

Just to understand you correctly


+--------------+           VPN                +------------+
| Webserver |---------------------------| dbf file     |
+--------------+                                 +------------+
ASP script
runs here

Is this correct?

Does the code work if you put the dbf file locally on the webserver (not suggesting this as a solution but to eliminate whether it is a VPN problem or a config problem on the web server)?

yes, my friend, i have copied locally and it works fine...

I can put the same asp coding in a visual basic program and run it... i.e. on the web server and it goes through vpn and pulls the data from the dbf. (but it takes like 1 minute to get one record specified by the program i.e. where the fieldname = whatever)

To me it suggests security permissions, which i have put to basic permissions, etc... mapped a network drive...
pretty much everything...

Thanks in advance :)

Ok,

Next stage is what happens if you put the file on another resource on your LAN - i.e. leave out the VPN and use another workstation on the same LAN as the server - does that work.

intriguing.  that was something i should have tested... but did not......
i get an error

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC dBase Driver] '(unknown)' 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.

i set up the dsn on the web server and the dbf on another machine lan based  but no joy, tried the following asp
Set whConn = CreateObject("ADODB.Connection")
  whConn.Open "Driver={Microsoft dBASE Driver (*.dbf)};" & _
                      "Dbq=f:\testwhdb" also trued UNC

also did normal dsn.

You are a superstar

I unticked the IIS5 allow iis to control password, and typed in the uid and pwd of the remote machine and it all worked :)

Thank you very much...
