I have a pair of MS2000 clustered servers connected to a stack of 3750 switches on ports gi1/0/9 and gi2/0/9.
After a failover of the ms cluster, the original primary node cannot be 'pinged' outside its VLAN.
You can ping it within the vlan, and from the switch, even using an extended ping with the ip of another vlan, but not from anywhere else.
I am about to put a sniffer on the thing but wondered if anybody has seen this before.
Regards
Kev
