Problem solved / culprit found!

Behavior in question:

The last character of the service name is truncated and couldn't find
service

First off, this behavior is pretty well documented....it even appears noted
as an odd behavior in a MS White Paper.  Normally not a big deal as MS
clients
would provide a few requests with the truncated service name the correct
itself.
For example you can get a Windoze client to repeat the situation by
requesting
properties of a share from explorer and it will result in 3 or 4 truncated
service
name requests.

My problem was the client was spamming the server with > 1000 requests / sec
flooding logs and bogging down the server.

My situation was related to resident software on the client called:

CyberLink Media Libray
HP TouchSmart
HP MediaSmart

I think they are all basically the same product with different names

One of these processes was spamming the server looking for media I suspect.

I uninstalled it and the spamming stopped.

In particular the problem resided with a process call CLMLSvc.exe.  Once
killed
the spamming went away.

Matt, I would check you clients for similar software.

Cheers
Brian
