Got a sb server 2003 with four workstations.  Have one workstation that logs in successfully, but when trying to ping the workstation from server (or any other workstation, I get nothing - all packets lost).wondering what the problem could be,  It is a Win 7 with network discovery turned on, could it be a firewall problem?  something must not be configured properly. Only computer with that problem.  Trying to find list of utilities and commands for TCP/IP, but haven't found what I need.

sounds like firewall mate, go to firewall settings and enabled file and print (ICMP echo IPV4) on Domain or private if they are not on domain.

just set up a linksys router with DHCP and firewall recently, I went into the firewall, but I am not sure what rule I need to set up to allow file and print.  Is ICMP a command? (utility)

 

I've got a couple of screen grabs to look at, I thought everything is open

JohnnyJammer was referring to your Windows/Windows server firewall settings. HERE is a list of tcp/ip commands.

ICMP is a protocol.

http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol

 

The routers firewall has nothing to do with local lan traffic.  It is only concerned/looks at traffic coming though the router and usually only inbound not outbound.  This is where you would use a software firewall to alert you to the outbound traffic.

 

You would look at the software firewall installed on this windows 7 box and set it to respond to icmp requests [ping]

Thanks for all the info,  guys!

 

I'm going to check further to see what is going on.  I used ping as a command and ip config all.  I haven't messed with this stuff in years so I'm a bit rusty.

Even though you can't ping are you able to access the internet or share folders?

Yes, It can see the server, access the internet and see the other computers.  It was only when I wanted to share a folder on a USB drive connected to it externally and map a drive from another computer that I realized it couldn't be reached.

 

I made sure that file and print sharing was on, and when I tried to ping it from the server, it still couldn't reach it.  I then took the work station off the netwrok and then rejoined it and still no joy..

After ruling out Windows firewall (just turn it off) Or from an elevated command prompt type
netsh advfirewall firewall add rule name="All ICMP V4" protocol=icmpv4:any,any dir=in action=allow
Next would be a different network card.

Right, I'll try that, I do have a spare giabyte network card, I'll try that also, I'm going over there today sometime if I can get away.  I'll let you know how it goes.
