WScript.run output redirect fails

I am trying to call a command from WScript.run and redirect that command's output to a file.
When I call:

errCode = oShell.run("%comspec% /c nslookup " & ipStr,0,True)

everything goes fine and errCode gets a zero.  When I try:

errCode = oShell.run("%comspec% /c nslookup " & ipStr & " > " & filePath,0,True)

errCode gets a 1.  I have tried setting IIS to use the Administrator account for Anynomous Access thinking that this an issue of write permissions, but this didn't solve the problem.  When I enter the command in the run box, everything works as expected.

Please help.  Thanks.

The thing about setting the Anonymous User in IIS is this: You are only change the IUSR_ account, not the IWAM_ account (which is the account that your script is running under when it launches anything).

Provided your output path (the variable value of filepath in your example code) is located within your web site, you must perform these steps in order to save the file:
1. Change the account back to the IUSR_ account. No need giving Administrator access through your website.
2. Make sure that IUSR_ and IWAM_ both have Change permission on the directory that the file is to be saved to.
    - In explorer, go to the directory, right click it and select Properties
    - Go to the security tab
    - If IUSR_<machinename> and IWAM_<machinename> don't exist in the permission list, add them.
    - Repeat for each IUSR_ and IWAM_:
             Highlight account
             Check the Modify Permission (this will check Modify, Read & Execute, List Folder Contents and Write... Clicking the Full Control option gives WAY too many permissions - for an idea, click Advanced to see how many more)
3. In the Internet Information Services MMC, navigate to the directory that the file will be saved to (within your website) and click properties.
4. On the Directory tab, check the Write option, located in the center of the dialog.
5. Click OK.

That should allow you to pipe the command output into your webspace to access it later.

If your machine has the latest and greatest VBScript interpreter (5.6), you can get around having to pipe the info out at all and just read it directly from the stdOut of the command line like:

Set oShell = Server.CreateObject("WScript.Shell")
Set oExec = oShell.Exec("%comspec% /c nslookup " & ipStr)
Do
      tmpStr = oExec.StdOut.ReadAll()
Loop While Not oExec.Stdout.atEndOfStream
RetCode = oExec.stderr.readall

Set oExec = Nothing
Set oShell = Nothing

The variable tmpStr will now contain all of the info from the stdout for nslookup. The RetCode variable will hold the error code as you are accustomed to.

Hope this helps!
