I have Windows 7 x64 on my desktop, laptop, and HTPC. The past few months, everything worked fine. Today, I can ping my IP address but I cannot ping the host name on all 3.They also do not show anything in the network window, just the computer that I'm on.

Now, prior contacting the ISP in Bahrain (where internet is regulated due to the current political situations) we need to know whether anything could be done from our end to resolve this issue.
View 2 Replies View RelatedI have a small workgroup at home of about 4 or 5 computers. All the PC's, notebooks are running W7. I have one PC that I use as my "always on PC", with all my media and resources I use on it. The NetBIOS or computer name assigned to it is mediapc with a static IP of 192.168.254.150. All my other desktop PC's, excluding the notebooks, have a static IP also.The problem is more annoying then anything, and thus I only work on it intermittently. Today I decided to post after wasting much of another day attempting to resolve the issue.The problem is accessing my mediapc from any of my other computers while using the computer name, "mediapc". If I use the static IP assigned above, there is no problems. Everything works, RDP, Dameware, Telnet, SSH, Ping,Tracert, etc. If I use the computer name "mediapc" then it fails with an unreachable host error or similar. The reason it fails is because somewhere in my network or in the mediapc itself, it wants to resolve the "mediapc" name to an unknown IP of 192.168.254.47.
Now with this said, I can still share files and access the mediapc using the name in a UNC syntax, like //mediapc/data works fine or directly clicking on the mediapc share under Network works also. If I Ping mediapc from any other PC than itself, it fails with the 254.47 IP. If I try to use any remote connection software and use the name mediapc, it fails to connect.This is what I know and have tested:
1. Adding a host entry to all the client computers works but does not fix the root of the problem.
2. nslookup mediapc reports the wrong IP of 254.47
3. Remote connections as I mentioned above fail because the name is resolving to an invalid IP.
4. Pinging mediapc from itself, displays the correct IP of 254.150, although I have to use the -4 parameter.
5. Arp -a on all PCs report correct IP of 254.150 with the correct MAC address. (There is no 254.47 listed)
6. NBTstat -a mediapc reports correctly and shows the correct MAC address.
7. Network shares work correctly from and to the mediapc without issue. No access problems.
8. I have deleted all arp entries and flushed the dns with no change.
9. MS mentions to change order of the Bindings of the adapters, yet I only have one Local Area Connection.
How is a computers hostname translated into an IP-address?Eg. when i enter "\server1" into the "run"-menu i get access to my server at IP-adress 192.168.1.2, but how does my computer know what IP-address is it?
View 5 Replies View RelatedI manage the network of a small (120 users) network spread out over 5 sites within a 10 mile radius (for normal ops- extended ops can expand to include other cities).I think I'd call that a Campus LAN, perhaps it's just a really small MAN (for normal ops)...I am starting my CCENT/CCNA track so this may be blazingly obvious to some of you- but I'm sure to learn something either way...Every now and again we have to go find "hostname "X"" for an update that won't roll out by way of our (Server Sr SysAdmin's) tools, so we actually have to put hands on it. Unfortunately the prior admins didn't document the inventory to such a level that we know "laptop_015" is in the building down by the college.
I DO have documentation on my equipment (I'm the Network Sr SysAdmin) that I have rolled together over the last 9 months being here...I have a Cisco 5520 ASA, and use ASDM to manage it. What would be extremely handy would be the ability to put a query in the system to report back what switch a given hostname is plugged intoBetter yet, if it could tell me switch and switchport.I imagine this would be simple if I had the MAC address- there's got to be a way to grep the switches for a given MAC- but not sure if it'll work in a similar fashion for ARP lookups.
I am having trouble with getting a copier that I have networked to stay registered in the system. When connecting all the equipment back for the new year I was having trouble getting this one specific copier back online properly. I used to have it assigned with a static IP because the person that was here before me had all the computers map the printer using the IP instead of Hostname but that was causing IP conflicts so I removed it and mapped the printer through Hostname which is made "MPF-TOSHRM328"So now for the actual problem, after the copier got the new dynamic IP of 10.8.214.151 i thought it would be fine and everything would click in because it was mapped to the host name and not the IP. But when I do a tracert on the hostname it still shows up with the old IP. and now that the old ip has been reassigned it actually points to a physical machine now. Weird. All attempts to flush the DNS have not resolved the issue. I even tried going in and deleting the entries in manually. No luck. As a point of reference here is the result from the tracert.Tracing route to MFP-TOSHRM328.78B450.nycboe.org [10.8.214.126] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms SLS330W09 [10.8.214.126]Trace complete. I should also mention that this server is only here in the sense that it is the DC for the computers on this floor. There is a whole other system that assigns the IP's and handles the DNS. I do not have access to it, it is run by the main network people at the central offices.

As far as I understand it Fault Manager need to be able to do reverse lookup for ip adresses to show the correct name in the "device name" column. I have double and tripple checked and all devices that only is shown as an ip address do have a reverse in the dns used by the LMS server. The device is correctly registered and inventory have been run. If I hold the mouse pointer over the crosshair on the row of the offending device all info is shown including correct device name and fqdn.

View 4 Replies View RelatedI have a big problem with my Cisco EA6500 router. I have a domain that is pointing to my public IP address of the home network. I have various computers and applications that listen on different ports for various reasons on this network. Everything worked fine until a week or so ago when I had to restart the router. The reason was that while I did a routine change (add a Mac filter for wireless) the router stopped responding. After restarting it, I could not access the home computers through the domain name (public IP) while being inside the network. If I try from outside my LAN it works fine but when trying from within the LAN the hostname and IP are not reachable. Also, everything works from inside the LAN if I'm using LAN IPs.

View 4 Replies View RelatedI have just had my broadband upgraded to FTTC which means my router has had to change. Previously I was using a Thomson TG585v7 ADSL thingy provided by my ISP. One nice thing about that router was that it would act as a local DNS and allow me to find my other machines on the network by using <hostname>.lan instead of IP addresses.
I've now switched to a Linksys WRT320N ethernet router which connects to my fibre modem, and which I've updated to the latest firmware (1.0.04). I have 2 machines on the network which I regularly want to connect to each other; one is running Windows 7 and the other is running OS X Lion.
The problem I'm having is that I'm unable to connect to my Win7 machine from the OS X machine using the Win7 machine's name. However, I'm able to ping the OS X machine from my Win7 machine using the hostname.
I am working on adding a mapping to our external address for our mail server - let's call it mail.example.com
I would like to be able to access mail.example.com internally for our user's smartphones - if they access our company WiFi they are not able to get mail using the mail.example.com as the server name in their phone setups. However, once they leave the office and use any other WiFi it works fine. Also, I am unable to ping that address from any internal device. I believe also this is the reason Exchange accounts do not work on our site to site VPN connections.
I have a ASA 5520 and work primarily in the ASDM 6.4 to do configurations in the main office and have 5510 in our site to site connections.

If I hardcode the DNS servers IPs in the "dns server-group DefaultDNS" I am able to resolve the hostname. If I then remove the IPs from the group and rely on the dhcp to assign them, when I try to resolve the name I have an error at the console "ERROR: % Invalid Hostname"

View 3 Replies View RelatedI have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.
View 5 Replies View RelatedI set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.
