in reply to Win32API::Net::GetDCName returns error code 87 for remote servers

GetLastError results in error code 87 (ERROR_INVALID_PARAMETER).

The MS description of the underlying function suggest that error 87 for that api means: "The name syntax is incorrect. This error is returned if the name specified in the servername parameter contains illegal characters. "

It goes on to caution that whilst the server name can be in either DNS (microsoft.com) or Netbios (microsoft) form; the domain name can only be in the latter form.

I'm guessing that you are supplying the server name in a format that the call doesn't expect. Hard to confirm as you feel the need to redact the name in your posts. If you posted a fictitious name that is in the same form as the real ones you are using, someone might be able to see the problem.

    For server, I have tried: "BW2012R2", "BW2012R2.TESTLAB". My domain is "TESTLAB"

      According to this netbios names are padded to 15 (or maybe that is 16, somewhat confusing) characters with spaces.

      My suggestion is to run the command nbstat command and see what it thinks the names are.

        nbtstat output:

        I tried padding the server string out to 15 and 16 characters using space with the same result.
