I need to change dynamically some DNS registers of our domain
I figured that a WS would do the job so I developed a WS that has only one web method that receives an ID and an IP address from it clients. It verifies the ID and then proceeds to change the DNS pointer with the “dnscmd.exe” utility on a Win2000 server

<WebMethod()> Public Function Nueva(ByVal quienSoy As String, ByVal miIP As String) As Strin
       Dim miPInfo As ProcessStartInf
       Dim miProc As Proces
       Dim regreso As Strin

       miPInfo = New ProcessStartInf
       With miPInf
           .FileName = "C:\WinNT\System32\dnscmd.exe
           .Arguments = ". /RecordDelete diato.com.mx " & quienSoy & " A /f
           .RedirectStandardOutput = Tru
           .UseShellExecute = Fals
       End Wit

       miProc = Process.Start(miPInfo
       miProc.WaitForExit(
       regreso = miProc.StandardOutput.ReadToEn
Return regres
End Functio

When I run these method I get a “Command failed: ERROR_ACCESS_DENIED 5 (00000005)” as the return string (StandardOut of the process

I went a added a user in this machine and made it a member of the “administrators” group
I used the ASPNET_Setreg utility to encrypt the user name and password in the registry

I added these lines in the Web.Confg file

<identity impersonate="true
userName="registry:HKLM\SOFTWARE\MyApp\MyId\ASPNET_SETREG,userName
password="registry:HKLM\SOFTWARE\ MyApp\MyId\ASPNET_SETREG,password" /

I restarted the system and I get the same error message

What am I doing wrong
What else do I need to do
Is there a smarter way to change DNS registers

(Of course, if I run the dnscmd utility from the CMD box it runs ok

Thanks
