Endpoint Security and Control v 10.0 clients update very slow.

Running client version 10.0 now on 65+ machines on our company network (they all got updated to the new v10.0 automatically a few weeks back but that's another issue).

All clients are running Windows XP and the Win2k3 server is runniing Enterprise Console 4.5.1.0.

A few of our newer PCs are experiencing extremely slow updates from the Enterprise server.

It seems whenever there is an update available, it takes anything between 5-10 minutes for the client to update during which time all other processes come to a crawl and the PC becomes unusable.

Here is an example from the the client log:
