Event ID 16 SOAP error

[MAdrox]

I'm getting this error across a dozen front end win2k sp4 web servers
at random times throughout the day. It puts 4 event id 16 errors in
the app event log. Just to be sure I've isolated 3 web servers to
their own GB switch to make sure it wasn't connectivity issues and
that didn't do anything. We also have the SOAP 3.0 loaded as well...

Here are the errors:

Any ideas? I've searched the web for 2 days with nothing helpful.

Thanks for your time!
