\\UNC and ASP

[David R.]

I have two servers. One contains the ASP web application (\\Server1) and
the other contains the data files (\\Server2).

I'm having some problem with the following "file download" code at line
"adoStream.Load FromFile(FPath) ".

The error is "ADODB.Stre am error '800a0bba' / File could not be opened."

Could someone please offer some suggestions?


<%
Response.Buffer = False
Server.ScriptTi meout = 30000
Response.Conten tType = "applicatio n/x-unknown" ' arbitrary

fn = "MyPhoto.jp g"
fpath = "\\Server2\g$\f iles\MyPhoto.jp g"

Response.AddHea der "Content-Disposition", "attachment ; filename=" & fn
Set adoStream = CreateObject("A DODB.Stream")
chunk = 2048

adoStream.Open( )
adoStream.Type = 1
adoStream.LoadF romFile(FPath)
iSz = adoStream.Size
Response.AddHea der "Content-Length", iSz
For i = 1 To iSz \ chunk
If Not Response.IsClie ntConnected Then Exit For
Response.Binary Write adoStream.Read( chunk)
Next

If iSz Mod chunk 0 Then
If Response.IsClie ntConnected Then
Response.Binary Write adoStream.Read( iSz Mod chunk)
End If
End If

adoStream.Close
Set adoStream = Nothing
Response.End

This only works, if the anonymous user account IUSR_ has access rights over
the network, and by default, it has not.

Could you please tell me how to set that up?

Thank you.

Re: \\UNC and ASP

I recreated the IUSR/IWAM accounts reset/resynced passwords on the remote
server and gave them Full Control (figuring it was permissions thing).

However this did not fix it and I still receive the same message.

Here are my questions
1. What permissions are need for the ADODB.Stream to read a remote
filesystem (ie., what security context is it currently running under, please
don't say SYSTEM)?

2. If this is not possible are there any alternatives to the ADODB.Stream to
download a file from a remote filesystem?

What he means that you reconfigure IUSR account.

Create a network user account, that is not a 'guest' member.
Then apply that user to the anonymous account, and make sure that the
\\SERVER\SHARE also allows that user and the NTFS permission on that remote
file system allows that user.

Re: \\UNC and ASP

So, on \\Server1, I would change the password for Server1\IUSR_Se rver1 in
IIS.

Then on \\Server2, I would create Server2\IUSR_Se rver1 account with the same
password.

Is this correct?

No, since IUSR_ blah has no access rights on the network share.

Just create DOMAIN\IUSR_bla h

and on both IIS servers, you configure these accounts, by applying them.

These accounts, must be user accounts. It's a penalty in security so be
aware of that.
