C# Create OU in Active Directory

I'm struggling to create an OU for Active Directory using the code below.

strPath = "OU=TestOU,DC=Internal,DC=Com"

DirectoryEntry objOU; 
objOU = ADentry.Children.Add(strPath, "OrganizationalUnit");
objOU.CommitChanges();

The problem is strPath contains the full path 'OU=TestOU,DC=Internal,DC=net' so using .Children.Add is making the ldap path 'OU=TestOU,DC=Internal,DC=net,DC=Internal,DC=net' which results in an error as the domain obviously doesn't exist.

My question is can I create an OU using strPath without .Children.Add?

I'm not familiar with AD and this is something I inherited from the guy before me.

• The only way to create an object with System.DirectoryServices is to create a DirectoryEntry object to the parent and use DirectoryEntry.Children.Add.

  I think your best move at this point is to use the path you have and extract the part you need ("OU=something").
