Re: [nv-l] PC becomes Router !!

[George deSocio <desocio@us.ibm.com>]

One more thing would be to run the snmpget
I suggested.  There can be a difference between what is set in the
registry and what the agent sends in response to an snmp query.
I have found that after setting the
registry value one way or the other, a reboot was required to make the
mib reflect the change in the registry.  The reboot was my last resort
after recycling everything I could think of, but it worked for me.

Regards,
Geo.

The ipForwarding value is "not forawarding"
and the Windows Key 
"IPEnableRouter"  is 0.

I have another PC with similar configuration but without this issue.
The main difference between both PC is the one with the problem is 
hosted on a blade (in IBM blade center) and the other one is a server 
hosted in a "standard" box.
