can't ping server but connects to internet

the clients have gateway and dns of 192.168.10.1.   subnet 255.255.255.0 (same as server)

Rick's idea sounds correct.  also make sure of masking.  Can the server use the Internet?   Is there a policy on the server to not allow ICMP (ping) (rare).  Is there a firewall active on the clients?  You should be able to narrow the issue down by using the server and 1 client for testing purposes.  Ping the gateway, ping a known good address on the Internet such as 4.2.2.2.  Once both client and server can access their gateway and Internet an IP problem would be fixed.

oh and the server can ping all the pc's

Are the clients getting their addresses via DHCP from your server?

If they are what settings are you sending to the clients via DHCP?

If they are not are you manually giving them their IP address information or is the router doing DHCP?

You don't have both the router and server with DHCP turned on do you?

I currently have on the router's dhcp. I turned it off and tried the dhcp from the server but they were still picking up 192.168.10.1   The scope was green once I turned off the router's dhcp. But after turning it on there's no internet connection. And they still can't connect to server

Is there DNS on the server?  If so then the DHCP scope needs to be changed so that the server is DNS.  Ping is bidirectional, if you ping one way then IP shouldn't be the issue.

the scope has:
router: 192.168.10.1, dns: 192.168.10.2, range: 10.1 - 10.254, excluded: 10.1 - 10.50

give the workstaion a static IP that is one off from the server , do not give it ANY dns , now can you ping the server ?

Did you setup a zone on the servers DNS or just turn DNS on?

I tried giving a static IP address of 192.168.10.3. No DNS. still can't ping

tried giving server a dynamic IP and still can't ping that one either

ok you have a workstation now with no DNS at all right ?

the IP is like 172.16.1.10 for the server and the workstation is like 172.16.1.11

mask for both is the same like 255.255.255.0 and the gateway is the same

like 172.16.1.1

right?

sorry did not read your earlier posts carfully , you have the IP's there

192.168.10.2 Gateway: 192.168.10.1 this is the server

so give the WS 192.168.10.3 with the same mask and the same gateway

also open a command prompt from the workstion and "route print"

post it here

reboot the workstion after making the IP changes

On the server, right click on My Computer and Manage.
Go to Services and Applications -> Services
Scroll down until you see Windows Firewall/Internet Connection Sharing (ICS).  
Right click and stop the service.  
Try pinging the server from a workstation.

Edit the service and change the Startup Type to Disabled if you want to make sure it doesn't come back on.

heaklethorn is that you ?

Not me... must be a different Brian Heck you're thinking of, perhaps.

i used to work with a Brian Hekelthorn , though it may be you

welcome to EE , it is worth the money for sure!!

Thanks... hopefully I'll be able to give back.  I enjoy attempting to answer questions because it helps me get better and learn more too.

Windows Firewall is stopped already. I tried the workstation again with 10.3 and no DNS. Restarted the WS and still nothing.

Don't know if this helps but if I do a trace route from modem, this is what I get:

Traceroute to 192.168.10.2 (timer gran. 10 ms)...

this is wierd can you ping the gateway now from the workstation , is there more than one nic on the workstion and what is the result of "route print"

Can you ping the default gateway?

Is the service stopped/disabled on both the workstation and the server?

If it's still turned on for the workstation you can go into Control Panel -> Security Center -> Windows Firewall and edit the Advanced tab.  There's an ICMP option where you can allow echo (ping) requests.  You can also check Exceptions to see if file and printer sharing is enabled, although this should not restrict the workstation from accessing the server.

I would make sure that the actual service is stopped and disabled within the services list, however, on both server and workstation.

Can you ping 192.168.10.1 from your PC since that's your gateway/router?  

I bet you cant it would have shown up on the first line on the tracert

try to ping the WS from the server

Oh, also try from the workstation's command line:  ipconfig /flushdns

You could also try to just let it get it's own IP address rather than assigning one, and if you do that, do an ipconfig /release and then ipconfig /renew from the command line too.

what i am tring to do here is simplify it till it works ,

so i think getting a static to work first would be the way to go no DHCP and NO DNS on the WS and reboot the workstation and server

Can you do an ipconfig /all on both the server and workstation and paste the results in here for us to analyze?

Also, is the Router the DHCP server or are you having the SBS be the DHCP server?

Curios - what OS is running on the clients?

Okay, first, the ping was from the modem (router). Yes, I stated earlier that I could ping the workstations from the server. All the pc's get online and I can ping the gateway (192.168.10.1) from all pc's and the server. This will be the third time I did the static IP address on the workstation but I'll try it again.

I had to deactivate the dhcp on the server because no one was getting online and still couldn't connect to server. So I enabled dhcp on the router and this allows the internet connection. I get you the result of the ipconfig /all in a minute

hmm this is intersting , is there any way a static route is messing this up ?

start ...runn cmd "route print"

Ok, back to basics need more info to be sure.

Are Clients using DHCP?
Can Clients ping eachother?
Are VLAN's Configured on switches?
Any chances a network connection/cable went bad?
Run "netsh firewall set icmpsetting 8" from cmd prompt to enable ping replies if firewall is the problem.

Get back with these TCP settings and I'm sure you will have an answer in no time xD

GL,
    Rick

the clients are using dhcp
the clients can ping each other
not sure if vlan are configured. I didn't set up this network. just walked in blind.
there's a linksys switch & a belkin wireless router

i  would suggest you "simplify it till it works" , take the router out of the question Use static  addresses , you need to isolate what it is not the problem , so take the server , the linksys switch and attach it to ONE workstaion ,

SERVER>>>>LINKSYS<<<<<<WORKSTATION
192.168.10.2                            192.168.10.3

you need to have no DNS OR dhcp or router  there is no reason to intoduce complexity into this untill you solve this fundimental problem , once you get the workstaion pinging the server you can add layers of complexity to the enviroment (DHCP ,DNS , router ect ) to see what breaks it

the logic here is an old addage "simplify it to it works"  in this way you can know what is NOT wrong

if the above configuration works then you know that there is nothing wrong with the 3 componants (server, workstaion and switch ) and you can build on that , if this does not work simplfy it even more , use another switch that is known to be good ,if the workstion still cant ping the server use a laptop that has never been on the netwrok that you know is good. ISOLATE the problem  , get it down to the smallest componant that is the cause of the failure  

i think you get the picture SIMPLIFY IT TILL IT WORKS

make sure you document every change you make even down to what box is plugged into what port ect.  you will want to slowly build back to the original config step by step after you get the workstion to ping the server to see what is breaking it

to be more specific

SERVER>>>>LINKSYS<<<<<<WORKSTATION
192.168.10.2                            192.168.10.3
255.255.255.0                           255.255.255.0
192.168.10.1                              192.168.10.1

and check for static routes on the workstaion

start...run..cmd..."route print " look for persistant routes

And give us an ipconfig /all from the server and a PC - that would help with information.

Okay, I connect on the server, workstation and switch. no dns or dhcp.
statics:
192.168.10.2 (server)
192.168.10.3 (also tried 9) workstation
255.255.255.0

still was not able to assess anything from server.
was able to see and ping workstation from server



Also, ran route print: no persistent routes



server ipconfig (dynamic)
192.168.10.8
255.255.255.0
192.168.10.1
DNS:
192.168.10.1
192.168.10.2
 
workstation (dynamic)
192.168.10.4
255.255.255.0
192.168.10.1
DNS:
192.168.10.1

run a route print on the server if you have not allready

lets look at "active routes" on the workstaion and server , do the same thing route print on ws and server and post

no persistent routes

any "active routes "

any other wierd firewall type software on the server Blackice ? macafee HBSS or anything

we need to isolate the problem , do you have a laptop or something that is known good ?

a switch that is known good?

is there 2 nics on the server?

anoter thing we might want to try is to record all of the TCP/IP settings on the server and remove TCP/IP and reinstall it and manuully enter in the settings ,

goal now is to ISOLATE the issue to the server

no other firewalls. just opened a new switch.  know good laptop.

only one nic

i'll try uninstalling tcp/ip

so you have a new switch and a good laptop and still no luck?

be sure to record all TCP settings

what were the symptoms of the orginal failure ?

what do you mean by the "network went down"?

Wait - the ipconfig results show your server @ 10.8 and your workstation @ 10.4 not the 10.2 (server) and 10.3 (workstation) statics that you mentioned earlier.

Can you ping 10.8 and 10.4 from either location?  For you to have multiple IP addresses you must have 2 NICs on each machine, both plugged in.  Do you have 2 NICs on the server and PC?

Ping 10.8 from the workstation
Ping 10.4 from the server

What are the results?

I'm sorry this last time I allowed the server to obtain a dynamic ip. it no longer has 10.2 (which was static)

this happened over the weekend. they came to work monday with no internet connection and couldn't access network files.

I have to goto a meeting at 14:00

but if removing TCP dont work , then remove NIC driver and readd
then we will have to look at the physical nic ,

do you have a spare NIC?

I would avoid any DCHP untill this works with static addresses

can you ping loopback ?
from server ?

yes, i have a spare nic. i'll try that and post it so you can read it later. thanks in advance

make sure you record ALL NIC settiings

IE           full duplex ect .

try to unistall the current NIC driver first

thanks. main problem was that firewall was starting automatically instead of disabled on the server. thank you sooo much

no problem man ...any time
