Errors on ifconfig

I have an ongoing problem with my mail server. From my XP machine, there are times I cannot connect to the mail server. When I do a netstat, I get a message similar to: SYN

I cannot telnet to 443 when this happens either. I did a ifconfig on my mail server and receive this:

eth0 Link encap:Ethernet HWaddr 00:19:B9:B0:11:69
inet addr: Bcast: Mask:
inet6 addr: fe80::219:b9ff:feb0:1169/64 Scope:Link

Interrupt:11 Memory:f8000000-f8011100

uname -a:
Linux 2.6.9-55.0.2.ELsmp #1 SMP Tue Jun 12 17:58:20 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

Network controller:
05:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 11)

Does this sound like more of a network card/driver issue or a network bandwidth issue?

Carrier errors usually relate to the cabling but can also be NIC or switch/hub problems (bad contacts on RJ45 sockets)
