SSDP Discovery Service

[Dan Brinkmann]

Everytime I would click on a new email message in Outlook
it seemed to take unusually long to retrieve the message.
The behavior was consistent whether I was connected via
VPN, wireless, or local.

Today I started sniffing my connection when opening email
messages. I noticed a few frames everytime I opened a
message that did not seem to be consistent with the
traffic a PC generates opening an email message.

Here is an example of the traffic:
RPC traffic to email server
TCP traffic as email message is transferred
SSDP traffic to a multicast address - questionable traffic
ICMP destination unreachable from the gateway -
questionable traffic

Most of what is on the web is related to MSN Messenger
generating this traffic and the only way to stop the
traffic is to exit MSN Messenger. I tried this and the
result was the same and Outlook access was still "slow".

After stopping and disabling the "SSDP Discovery Service"
the traffic ceased and Outlook response was greatly
improved.

Why is this happening? Has anyone else experienced this?

You failed to mention your version of Outlook but I assume you are talking
about Outlook 2002. You will most likely get the same results when you
disable Messenger Integration in Tools-> Options-> tab Other.
