3rd NIC Killz file access

[Baba]

Good morning,

I have two W2k3 servers, one is Server, one is Exchange
2003, that have had two NICs for quite some time now.
One NIC is for the user/data access and the other has
been used strictly for the backups. Using the Intel
PRO1000 MT network card, I enabled a third NIC so we
could set it up as a dedicated RPC over HTTP proxy port
for remote e-mail checking.

Whenever the third port is enabled, file and e-mail
access by LAN users slows to a crawl. I do not have
default gateways entered for any but one of the NICs, and
I have disabled NetBIOS over TCP/IP on the other two
ports as well. Does anyone know why my servers lose it
when three NICs are enabled?

Many thanks,
Baba

Possibly:

1. If an adapter is enabled but not connected, you can experience network
slow down.

2. The 3rd adapter may be at the top of the binding order. Right click My
Network Places, select Properties, click Advanced, and select Advanced
Settings - move the LAN connection to the top of the binding order.

3. You may have conflicting DNS record issues, especially if the server is
also a DNS server or domain controller. See:

Doug Sherman!! Thanks for your advice.

The binding order was, by default, LAN3 on top and LAN1
on the bottom. Good catch. I'll give it a go and re-
post when I have results.

Thanks again, and sorry for the double post earlier.
Just a slip of the brain...
