I am trying to connect to a domain using the NetJoinDomain API. I can successfull use it to change the workgroup. But when trying to change the domain I get one of two errors, using the same input. I either get "No such domain" or "No mapping for the Unicode character exists in the target multi-byte code page." This is using the same exact inputs, I have hard coded the inputs in for debuging purposes.

What am I doing wrong?

Also for some reason I have to convert the strings into char arrays and insert a null value between each character. Anybody know why?

visual basic code:

Private Declare Function NetJoinDomain _    
Lib "NETAPI32.dll" (ByVal lpServer As String, _    
ByVal lpDomain As String, ByVal lpAccountOU As String, _    
ByVal lpAccount As String, ByVal lpPassword As String, _    
ByVal fJoinOptions As Int32) As Int32Public Sub ChangeDomain()        

Private Sub ChangeDomain()

Dim d() As Char        
Dim u() As Char        
Dim p() As Char        

' I replaced what the actual values are, since they were my username and password to the company domain        
'InsertNulls is a function that I created to convert the strings to char arrays and insert null chars between each value        
d = insertNulls("myDomain")        
u = insertNulls("myUserName")        
p = insertNulls("MyPassword")        

err = NetJoinDomain("", d, "", u, p, JoinOptions.NETSETUP_DOMAIN_JOIN_IF_JOINED Or JoinOptions.NETSETUP_JOIN_DOMAIN)

End Sub
