Hello,
I need some more information on Net Send Command.
I know how to use this command and for what it is used, but i want to know about the security risk if this command is available for use within a LAN.
Can anyone Hack a PC if Internet and Messenger Service(Net Send) command is enabled on that PC.
Is There Any other Security Issue that originates due to use of Net Send?
Please Can anyone provide some info. as i need to make a decision on this issue.
Any info would be great help.
Thanks in Advance, awaiting a reply soon.

It isn't more dangerous than anything else. It can, however, be a nuisance. Make one mistake and you send your message to a whole group or the entire company. I've seen it happen a few times, but usually only once 
I wouldn't disable it, but not advertise it's status either.
Cheers,
Sebastian

You have Everyone Set under Share permissions, what do you have for NTFS permissions on the folder?

Much depends on your desktop, if you're connected to a network with Microsoft AD, is not access, even using alternative command or trying to change ACLS.
Describe the situation

I noticed that there is a dword in the regedit located at HKCCONFIG > software > microsoft > windows > current version > internet settings --- and that the default value setting on my xp sp2 has it set at a value of 0 which I assume means that the proxy is turned off - so I changed the value to 1 which should turn it back on, which seems the more logical thing to do.
Do xp sp2 cd disks all come with that setting set at zero?
I do not have any windows updates installed on the computer although I did a bios update ,A01 revision download onto my Dell computer, unfortunately,from the Dell site; and also recently I installed ubuntu 8.04 and the newer 9 version temporarily onto my computer from ubuntu cd disks-- and they all did some modifications to my xp sp2 operating system and I wonder if that accounts for that ProxyEnable default setting?Can someone tell me if that default setting of zero is what all xp sp2 cd disks [Home Edition] come with?
- thanks, winch1020

Yes, the Proxy settings are off by default. Well, I should say that it's probably "AutoDetect".
There is more than one registry value that controls the proxy settings. Just changing that one value alone won't do much. If there is no data in corresponding values, then what you did was invalidate the setting and IE might just ignore it, or reset it back to a know state.

Hi, by configure each client machine with ISP DNS IP to access an internet and configure each client machine with internal DNS server (and this DNS server forward the request to ISP DNS server), which method that will apply to the below situation:
1. Decrease internet usage
2. Decrease network bandwidth
Thank,

No. I'm desing a network for my office. Currently I configure each client with primary DNS to my DNS server and secondary DNS to ISP DNS server. The day before yesterday my internet usage in my office is 2200 Mb which is 50% of my internet plan per month. Because I didn't deploy ISA yet, i could not know who was using an internet. So I just want to know which method of configure DNS setting at the client site that will help me to reduce network traffic.
PS: Currently I didn't study any course. I'm a person which is study by myself from the book of Microsoft Press. Whether I took Microsoft Exam, I don't have any chance to get out of the room to post the question for the solution on internet.

You should probably remove the ISP DNS entry from the workstations. You are probably forwarding local domain queries to your ISP. For example, user John wants to access the fileserver at FILESERVER.MYLOCALDOMAIN and your ISP is not authoritative for MYLOCALDOMAIN and generates a negative response.
If you have a single office domain and a single DNS server serving all requests for both LAN and WAN then you should probably configure your local DNS server as authoritative for MYLOCALDOMAIN and completely disable forwarding. Then you need to configure the DNS server to use root hints. Using root hints will make your DNS server not rely on the upstream DNS provider.

Yeah, remove the ISP DNS from the clients.
But, in any case, that's not going to reduce the traffic to the ISP by that much. A query is only 60 bytes, and you can't possibly make that may queries to account for that much bandwidth.
If every client has a direct connection to the router connected to the internet, you've got a problem. You need to reconfigure the network so that the only box that has the connection to the internet is the ISA box. Every client then has to be configured to use the ISA box as a proxy server. Only then can you track who's using the internet connection.

Thank you very much for your answer. Currently all of my client are connect directly to the internet with router as a default gateway and primary dns point to internal domain with the secondary DNS point to ISP. I do that because sometime my domain is not available to the user due to electricity problem. Next month I plan to deploy ISA server which would be remove this problem.

Obviously the internal DNS server will cache the query and return the cached result on subsequent internal requests. A DNS query is 60 bytes in size so you would decrease network bandwidth by 60 bytes * the number of duplicate DNS queries. There are other factors involved such as DNS cache timeout and such.
