Author Restrict SMTPSVC to UDP DNS under W2K Pro

I would like to configure the SMTPSVC to use UDP for DNS queries. A
method is explained in MSKB 330070, "Mail May Not Be Delivered When
DNS Resolution Uses Only the UDP Protocol".

According to that article, UDP can be configured with MetaEdit by
adding the name "36997" with a value of 2 (DWORD) at the location
LM\SmtpSvc\1

However, under W2K Pro SP4, this does not appear to have any effect.
"NETSTAT -n" shows that DNS queries still proceed via TCP, not UDP.

Is there any way to restrict SMTPSVC DNS queries to UDP under Windows
2000 Professional (SP4)?

regards, Andy
