Generic failure, wmi

[anders]

Hi!

Im trying to add a A record to a domain name in MS DNS with C#, it's done
from a webpage with this code:

ManagementClass rr = new ManagementClass (@"root\Microso ftDNS",
"MicrosoftDNS_R esourceRecord",
new ObjectGetOption s(null,new TimeSpan(100), true));
string _ResellerDomain Name = "mydomain.net." ;
object rrText = "web IN A 123.123.123.123 ";

rr.InvokeMethod ("CreateInstanc eFromTextRepres entation", new
object[] { ".", _ResellerDomain Name, rrText});

The record is added to the domain but I get this error even thou it worked:

System.Manageme nt.ManagementEx ception: Generic failure at
System.Manageme nt.ManagementEx ception.ThrowWi thExtendedInfo( ManagementStatu s
errorCode) at System.Manageme nt.ManagementOb ject.InvokeMeth od(String
methodName, ManagementBaseO bject inParameters, InvokeMethodOpt ions options)
at System.Manageme nt.ManagementOb ject.InvokeMeth od(String methodName,
Object[] args) at WebDNS.DNSClass .AddRecord() in c:\documents and
settings\anders \vswebcache\web admin\dnsclass. cs:line 30

All permissions must be correct thou the domain is added.
Have seen other with this error but no solutions!
Line 30 is the InvokeMethod
What is causing the error and what can I do to solve it?

Regards
Anders Aleborg

Forgot to say, the MS DNS is placed on a Windows 2003 Server webedition

Hi Anders,

Sorry for the late response.

For this issue, I think you are running the code in a ASP.NET web
application, right?

Could you please create a console application and run the code to see
whether it has any problem? If there is no exception in console
application, we may isolate the issue to the identity that asp.net web
application running on.

Besides, please also test the following sample code: (it is for console
app, you can change Console.WriteLi ne to response.write for asp.net app)

ManagementClass dnsRRClass = new
ManagementClass (@"\\ServerName Here\root\Micro softDNS",
"MicrosoftDNS_R esourceRecord", null);
ManagementBaseO bject inParams =
dnsRRClass.GetM ethodParameters ("CreateInstanc eFromTextRepres entation");
inParams["DnsServerN ame"] = sServer;
inParams["ContainerN ame"] = sDomainName;
inParams["TextRepresenta tion"] = sTextRepresenta tion;
ManagementBaseO bject outParams =
dnsRRClass.Invo keMethod("Creat eInstanceFromTe xtRepresentatio n", inParams,
null);
Console.WriteLi ne("Executing the method returns {0}",
outParams["ReturnValu e"]);

Thanks very much.

Best regards,
Yanhong Huang

Hi Anders,

Then that seems not related to ASP.NET security.

Have you tested the code that I pasted before? What is the return value
from the last line? Thanks very much for your update. :)

By the way, if it still returns error, could you please paste you .cs file
here? I will test it on my side and contact our supporting team to look
into it.

Thanks.

Have tried with this code as well, the record is created but it gives me a
generic failure message.

public string AddRecord(strin g domainname, string host, string
recordtype,int MXPrio, string target)
{
try
{
ManagementClass dnsRRClass = new ManagementClass (@"\\"+
System.Environm ent.MachineName +@"\root\Micros oftDNS",
"MicrosoftDNS_" +recordtype+"Ty pe", null);
ManagementBaseO bject inParams =
dnsRRClass.GetM ethodParameters ("CreateInstanc eFromPropertyDa ta");

inParams["DnsServerN ame"] = ".";
inParams["ContainerN ame"] = domainname;
inParams["OwnerName"] = host;

if(recordtype== "A")
inParams["IPAddress"] = target;
if(recordtype== "CNAME")
inParams["PrimaryNam e"] = target;
if(recordtype== "NS")
inParams["NSHost"] = target;
if(recordtype== "MX")
{
inParams["Preference "] = MXPrio;
inParams["MailExchan ge"] = target;
}

dnsRRClass.Invo keMethod("Creat eInstanceFromPr opertyData", inParams,
null);
return "ok";
}
catch(Exception ex)
{
return ex.ToString()+" <br><br>"+ex.St ackTrace.ToStri ng();
}
}

Yes, I have one more problem, when I try to delete a zone or a record it
takes time, about 40-60 seconds to delete a zone!!! And the CPU goes up to
100% on the server. It can't be normal.

The code:
Delete("Microso ftDNS_Zone", "ContainerName" , "domain.com ")

protected bool Delete(string sTableName, string sFieldName, string
sFieldValue)
{
try
{
string sQuery = String.Format(" SELECT * FROM {0} WHERE {1} = '{2}'",
sTableName, sFieldName, sFieldValue);
ManagementScope m_oScope;

m_oScope = new ManagementScope (new ManagementPath( @"\\" +
System.Environm ent.MachineName + @"\root\Microso ftDNS"));
m_oScope.Connec t();

ManagementObjec tSearcher oSearcher = new
ManagementObjec tSearcher(m_oSc ope, new ObjectQuery(sQu ery));
ManagementObjec tCollection oCollection = oSearcher.Get() ;

foreach (ManagementObje ct oObject in oCollection)
{
oObject.Delete( );
}
return true;
}
catch
{
return false;
}
}
