Server 2008 R2 looses network after each reboot

Hello

We have one server that has an unsuaul behaviour whenever it is rebooted

Basically, it nukes its network connection. Server restarts fine, no errors - but when it comes back up, cant ping, cant RDP - cant enumerate shares or anything

Connect to local console, the network and sharing center shows that its connected to the network (sometimes it shows full connection and still doesnt have connectivity)

Cant ping any network location from the server at all

Once I disable and re-enable the adapter - all works fine!

Tried all the following
Update driver
Netsh reset adapter
different network cable
Update network card firmware
Update bios on server
disabled all adapters on the server bar one
Tried another port (dual broadcomm adapter on server)
yelling at it

Nothing seems to have worked. Any reboot causes this behaviour - whether by scheduled task or manual

Its a Dell power Edge R300, Dual Broadcomm network adapters and no teaming

Please dont say 'disable ipv6' as a solution - its not a solution as far as I'm concerned

Firewall is disabled
Disabled 'network identification'

Did you assign a static IP or dynamic?

I had a similiar issue a while back. Even though I configured the IP, SM, GW, and DNS settings through ncpa.cpl, the network adapter was acting funny. I ended up hard coding the values through command line and it resolved my dilemma.

netsh interface ipv4 show int

netsh interface ipv4 set address 11 static 192.168.1.88 255.255.255.0. 192.168.1.1

netsh interface ipv4 add dnsserver 11 10.10.10.11 index=1

Good luck.

It is a statically assigned IP address - being a server and all

I'll throw netsh at it and see how i go

I did reset the TCP stack already

I've thrown Netsh at the server - and though the server sets the ip address correctyl, it still is having the same issues

I did know of an issue in some installs of Oracle Virtual box where the network adapter played havoc with the local network - this machine isnt running virtual box - but is running vmware server

I have an identical server that is running vmware server fine, is there anything else I can try?

Dell have the wrong drivers on their site for this particular server

Running AIDA on the system showed that this was a netxtreme 1 adapter but the dell website has the netxtreme 11 drivers

Though the drivers install - it wasnt stable. Rolling back to these drivers have alleviated most of the problems we were having

I have a case open with Dell as it still has issues with the network stack
