Vista - problem with SetDNSServerSearchOrder WMI function

uint32 SetDNSServerSearchOrder(
[in] string DNSServerSearchOrder[]
);

above is copy/paste from msdn site on this function. I keep getting error
70, which means invalid IP address but I know the IP's I'm supplying are
fine. The site said that it takes a 'list' of ip addresses but fails to
mention how that list should be delimited.. I've tried comma and space and
'or' with no luck, same error every time.

here is a snippet of my code, including some temp debugging stuff:
----------------------------------

Dim temp
aDNSServers = Array(PrimaryDNS & "," & SecondaryDNS)
For Each temp In aDNSServers
MsgBox temp
Next

sQuery = "SELECT MACAddress FROM Win32_NetworkAdapterConfiguration WHERE
IPEnabled = TRUE"

set colAdapters = oWMI.ExecQuery(sQuery)

For Each oAdapter In colAdapters 'all the NICs in the machine
MsgBox "configuring: " & oAdapter.MACAddress
iRetVal = oAdapter.SetDNSServerSearchOrder(aDNSServers)

If iRetVal = 0 Then
msgbox "DNS servers set."
Else
msgbox "possible error setting dns servers: " & iRetval
End If
next
-------------------------------------

aDNSServers contains 2 ipaddresses delimited by a comma. This has been
verified with my debugging msgboxs at runtime.

what am I missing here?

I have had problems in the past when trying to set something and using a
specific select statement ie "SELECT MACAddress...", but when I have done
"SELECT *..." it worked.

Thanks for the reply J Ford. I appreciate it. That has happened to me before
also and I didn't even think to try that for this one... turned out to not
be the issue in this case but I appreciate the good advice none the less.

In this case it turns out I'm an idiot (again)

this line:
aDNSServers = Array(PrimaryDNS & "," & SecondaryDNS)

is the problem. Even know I knew the IPs I was supplying were valid I
screwed up making the array. Above produces array with one element
containing a string with both IP's seperated by the comma. Improper use of
the array function. Should be this:

aDNSServers = Array(PrimaryDNS, SecondaryDNS)

and works fine when it is.
