Network connection problem with Windows 2003 Server

11-21-2006, 11:53 AM

Hi,

i have a network problem with a Windows 2003 Server (SP1).

It's a HP DL380G4 located with others servers in a remote site
connected through a Cisco site-to-site VPN.

Every 15 minutes:
- it stops responding to every network activity ( VNC, RDP, ODBC )
except PING from remote clients in LANs different from his own ( the
fact PING keeps working seems to me very odd)
- it keeps responding to every network activity within his LAN.

In fact, to keep working, I'm obliged:
- to connect to this server from another machine in his LAN
- then to DELETE the route table entry to remote clients it has created

- then it starts working again with remote clients for 15 minutes...

Help me!
Thanks in advance.

Do you have two NICs on the server?

The HP server has:

- 2 HP NC7782 Gbit NICs in teaming, connected to the LAN where we have
the problem
- 1 HP NC1020 Gbit NIC connected to the backup/administration shelf

Hi,

I have updated the Server with all patches from MS Update and with the
HP 7.60 Support Pack.

I've verified that the tctp.sys and that NICs drivers have been
updated.

The server now seems to work properly.

Thanks a lot !
Best Regards.
