Hi there,
             We have deployed SEP11 around our estate, hundreds of servers and thousands of workstations. We're also using GUPs to reduce bandwidth requirements.

I have 1 server that isn't updating its virus definitions. It has the green dot on the SEP shield so we know it can contact SEPM (and SEPM shows it as a client) but it will not update the defs. When i go to Help and Support --> Troubleshooting it doesn't show me the server info (it's all blank).

I would have expected the green dot not to show on the shield but it does. I can telnet on port 80 to the SEPM server using its FQDN and IP, and I can telnet to port 2967 on local GUP using FQDN and IP as well.

The Sylink monitor tool doesn't appear to give me much info either. Additionally, no proxy servers are specified in IE settings,and I've remove the proxy registry settings just to be sure.
The troubleshooting data shows the following (I don't want to post all of it here as I imagine it'll just clutter up this post even more):

Engines

SymEvent:  12.5.3.2
Auto-Protect Kernel Driver:  10.2.7.10

Any help much appreciated!
