--> I cant ping 172.23.0.2 port 8080

You typically can't ping a port, you ping an IP address.

--> please help me why cant I ping

If you are not in the networking group, why don't you ask them.  

Since you are at different locations, you are in different IP subnets.  It is possible that  you are not supposed to be able to access 173.23.0.2.

Hi Sam Kris,

Maybe if you could provide the IP, Network Mask for both your pc and your colleagues PC, we could start to figure out if routing is done or if you guys are even in the same subnets ?

Who knows, maybe there's some ip filtering done preventing you from accessing your target IP.

 

by: sam_krisPosted on 2009-11-05 at 05:00:44ID: 25748929

Nickbarau:-- ,,, his ip is 10.12.2.205 located in NY (router 10.12.0.103) , and my ip is 10.1.5.12 (router 10.1.0.102)  ,, he can ping 173.23.0.2 but I cant ,,,

Secondly: I cant access the admin share of users although I can access the desktops

--> I cant access the admin share of users although I can access the desktops

Are you supposed to be able to?  This means that your user-id is not considered a local admin on those PC's.  Somebody who is local admin authority has to put your user-id in the local admin group on each and every PC that you need local admin authority on.  The better way is to create a single user-id that has local admin on all PC's and when doing admin functions login using that ID.

You gave the IP addresses, but not the subnet masks.

If you are in the networking group, then you need to start looking at all L3 devices ( routers or switches that can do routing) and security devices (firewalls) to see what traffic flows are allowed from where.

I agree with giltjr, a lot of the the time the IP routing tables are setup with security levels that may allow forward traffic to flow from group 1 to group 2 but the admins may feel there is a security risk and disallow the traffic to flow backwards.
Secondly giltjr is also correct that ping is for ICMP and does not allow for specific ports to be checked, you need to use telnet or another application to specifcy IPAddress:Port
