RPC service question

[fokker]

Hello All,

I really need to know what the diffrence is between the 2 "LOGON" options in RPC service. If I change the "LOGON" option to "Local System Account" instead of "This Account" with user name "NT Authority\NetworkService" and password, will this open my system to attacks?

I also have some systems that are having issues with MS updates when I have the "LOGON" set to "NT Authority\NetworkService" and password.

Lastly, where is the registry fix for this?

Thanks

Fokker
