Unable to ping clustered servers - VLAN - Exchange 2007

[Guest MRKnMRSB@gmail.com]

I am trying to setup Exhange 2k7 running CCR - I have 4 servers for

exchange:

I have 4 servers that I will (meaning they don't have exchange on them

now) install the following roles:

1 Hub transport (HT)

1 Client access server (CAS)

2 Mailbox servers clustered

 

All servers are dell poweredge 2950's with Intel Pro/1000 (driver

version 9.12.13.0) PT Dual Port cards + onboard broadcaom BCM5708C

 

On each server I am teaming the intel nics using adaptive load

balencing

All the servers are on the same vlan

All servers are on SP2 with the latest patches + .net framerwork as of

2/22/2008

All servers are connected to a cisco switch

Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500-IPBASEK9-

M), Version 12.2(31)SGA, RELEASE SOFTWARE (fc3)

I have several Vlans and have no problem traversing them.

 

I have hard set the ports to 1000 full duplex -

 

Here is the problem: From my desktop (vlan X) I cannot ping the

clustered mailbox servers (vlan Y) by name or IP - I do an NSLOOKUP

and the name resloves and the IP resolves. I can ping the other two

servers (ht&cas) and RDP into them. Once I am on either ht or cas I

can then RDP into either mailbox server.

I have tried 'unteaming" the nics - doesn't make a difference.

 

I can also ping the server IP addresses from the switch that my

desktop is connected to.

 

I don't have a firewall on the two clustered backend servers.

 

Let me know what other information you need.

 

Thanks.
