DsGetDcNameWrapper Error, retrieving informations for GetDomain() call in SH 2.5.8

[mickdec]

Hi,
Sorry in advance if my explanations are not clear, its my first Issue, ever.

When i run SH 2.5.8 on a non linked domain trough LDAPS i got a GetDomain call failed at GetDomainsForEnumeration process.

Even if i specified the PDC as --domaincontroller, it seems that DsGetDcNameWrapper fail because DsGetDcName get a default null argument for computerName, resulting as DsGetDcName giving num 1355 (0x0000054B)

If i force the computerName parameter for DsGetDcName in DsGetDcNameWrapper at the process of GetDomainsForEnumeration, to be my --domaincontroller PDC argument, the process context becomes valid and Sharphound can continue his enumeration.

The error seems to continue after that, when processing ACE on each computer "the specified domain didn't exist." for GetDomain().
i am waiting now for SH to finish.

It can be a port problem (RPC 135 and/or Kerberos 88)

DcDiag with the Advertising test, which is using DsGetDcName() too return an RPC error in my case.

The ports 135 and 88 are closed from my VM using sharphound and the PDC.

I am not sure if it's the right explanation about this issue, but if it's the case, "manually" doing an LDAPS request to the DC asking for exemple (objectcategory=computer) using System.DirectoryServices trough powershell is working, without the port 135 and 88 opened.

Using DsGetDcName()(
[in] LPCSTR ComputerName,
[in] LPCSTR DomainName,
[in] GUID DomainGuid,
[in] LPCSTR SiteName,
[in] ULONG Flags,
[out] PDOMAIN_CONTROLLER_INFOA DomainControllerInfo
);

with ComputerName as the DC, and DomainName as the domain name (mydomain.com), did the job too, without the two ports open as well.
