2008 R2 networking issue

-

hi,

i've got dell r510 odd network issues, os 2008 r2 sp1, no nic teaming, builting broadcom bcm5716c double port nic has 2 fixed ips on different subnets.

the server restarts fine no boot errors , using console screen able login, unable launch number of things suchs example:

  • network , sharing center
  • local services
  • broadcom advanced controller suite

other things event viewer , windows explorer, browsing local disks work fine, server responds ping on hostname , network shares available fine.

after 15 minutes, applications , features launch fine , rdp works well. @ stage server behaves percetly normally. concerned network issue symptom of greater problem might affecting backups done on server of remote servers.

what have tried off top of head is:

  • different nic settings
  • checked nic bindings
  • different nic drivers (removed, updated)
  • with , without fixed ip address settings (both on dhcp)
  • different switch ports
  • swapped ethernet cables
  • dell support (who advised no hw fault after checking logs)
  • this command: "net localgroup "administrators" "local service" /add"
  • tcp chimney settings:

any ideas?


hi trana010,

thanks posting here.

> however unable launch number of things suchs example:

>network , sharing center

>local services

>broadcom advanced controller suite

after reading symptoms, i’d networking may not root cause of issue. i’d consider performance issue here.

if these services startup after time interval indicates services might got delay somehow since os boot up.

i’d suggest first check if same issue if reboot system “safe mode networking”. meanwhile, i’d suggest troubleshooting removing oem broadcom advanced controller suite form server reaming nic driver , see how going.

regards,
