[c-nsp] 2 IOS DHCP Questions

[Jeff Wojciechowski]

All:


1)      This one seems easy but not sure what I am doing wrong - I want to have my 2801 routers feed windows clients DHCP option 0001 with a value of 0x2 to disable NetBIOS using DHCP

a.       Tried several variations of "option 1 hex 0x00000002" in the dhcp pool config

b.      Error message I get back is "% DHCP does not allow raw option 1"

c.       (MS DHCP server says this option is for Win2k but if at all possible I want all NetBIOS gone so open to other ideas)

2)      I would like the same windows DHCP clients of the 2801 routers to "register in dns" with the dns servers they are learning via DHCP. When we ran centralized DHCP/DNS on the same 2008 servers, we had no issue with this. Now that DHCP resides on each local site on the router none of the pcs register in DNS.

Pool configuration for both above is:

ip dhcp pool 0
   network X.X.X.0 255.255.255.0
   default-router X.X.X.X
   dns-server X.X.X.X X.X.X.X
   domain-name *our domain name - just added this option this afternoon at my test site but haven't had anyone have time to reboot their pc yet

Router specs:
2801 running 12.4(22)T3

Thanks ahead of time for any and all insight...

Jeff
