XP Pro on a domain
recent installation of Symantec Endpoint11
When I tried to copy large email files (5+ GB) and other large files from the network to this new PC the PC basically freezes. I can move the mouse but it won't let me open any other applications, not even Task Manager.
I have re-installed SEP11 but removed the "Network Protection" module but the problem remains.
I tried another file copy from a PC on our network to this new PC. Before I started the transfer I opened the Networking tab in Task Manager. The files start to copy and you can see 75% network utilisation, after some time this just drops to ZERO.
I have tried another network cable and network switch. The problem remains. I believe it is related to SEP11. I completeley un-installed SEP11 and I seem to be able to transfer files OK.
Are there settings in SEP11 that I should adjust?
