Can NBT (netBIOS over tcpip) be disabled on cisco solution engine 1113 running 4.2?

Hello,

Would like to turn off NBT on our solution engine 1113 appliance but not seeing away via the web console. I've found documentation pertaining to disabling via ACS v4.2 running on a windows server but no info regarding the 1113 appliance. Does anyone know if this is possible?

thanks,

james

Hi James,

here you go with the list all of running and disabled services on ACS 1113 box due to security reasons.

Vinay,

Thanks for the response. That is correct for our 1113 appliance. I incorrectly posted the appliance model for my question. It should be the cisco solution engine 1120 which orginally came with the 5.x version but we downrev'ed to the windows 4.2 version to have both appliances at the same level. In looking at traces from our firewall from the csacs 1120 appliance I am seeing the following:

protocol: udp

service: nbdatagram(138)

destination : x.x.x.255

Attached is a caption from our firewall. Can the nbdatagram(138) be turned off? or is it needed for a certain service?

thanks,

james
