I have a small business environment that uses a domain controller and supports about 50+ PCs. Starting this morning multiple computers have lost their ability to obtain an IP address. We have rebooted our domain controller and tried various fixes on local machines with no luck.
View 1 RepliesI have three computers on my network. Two are wired and one is wireless. I continually run into the probably of getting a limited connection after the computer goes to sleep and I wake it up. I attempt to automatically correct it, but this doesn't work. I try to use the command prompt with ipconfig/release ipconfig/renew and it doesn't work. Then I try to disconnect the adapter and it doesn't work. I also reset the modem and the router with no resolve. Most of the time the only thing that works is restarting the computer. In addition I do use DHCP static addresses for the computers on the network. What is causing this and how do I fixt it without restarting the computer?
View 4 Replies View Relatedwe have been having problems with our wireless internet connection for a while now and have even changed provider without success.
What happens is that all our computers lose the internet connection from one moment to the next while the signal strength remains unchanged. when you try to sign back into the home network it is basically impossible. When rebooting the BT router it works, sometimes for a few moments only sometimes it lasts.I am wondering if the reason is that the computers are losing their ip address or has it something to do with the security key?
how do i assign IP addresses to 10 computers in a network?

View 3 Replies View RelatedNetgear DG834 allocates IP Addresses using DHCP to 5 computers and 2 tills, the tills addresses and one computer IP addreess are reserved and fixed, so that data can be downloaded from the tills to this computer. However I had to re-format the computer and the Router now allocates a new IP address to it, which the tills cannot recognise, so I cannot download the data from the tills to the computer. Is it possible to change the newly allocated Computer IP address in the Router back to the old one.
View 9 Replies View RelatedI can see what MAC addresses have a wireless session and I've used MAC Filtering to stop some MAC addresses from using the network at certain times, but they are still getting through to the internet. I don't know if they were to clone their MAC address as to whether this would show up with the cloned address in active sessions list. How I can stop some users from getting through at certain times? Any utility I can use on my Mac (Mac OS X 10.6. to show which computers/MAC addresses are on the network?
View 5 Replies View RelatedIn setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.
View 2 Replies View RelatedI am currently finalising my project in Uni and in the project planning section is asks if there are any ethical considerations to be made in my project. I am conducting penetration testing on a VIRTUAL network simulator (GNS3) using Metasploit toolkit. I am guessing I will need permission to download these tools onto the university network, would that count as an ethical consideration? If not, what would I say in this section? note, all of the data I am using in the project was created by myself, and there is no other human participation.

View 1 Replies View RelatedCurrently I'm with a pure Cisco shop, running every LAN Switched infrastructure (even in the HQ datacenter) with PVST+, I'm noticing in the documentation I've read and labs I've created that RSTP is... great, and I've observed that even the uplinkfast functionality seems to be build in by just enabling rapid-pvst. Of course I'll propose a migration plan, document the network, diagram it entirely and provide effective steps to implement the change, but that's assumed from any get'go.

View 1 Replies View Relatedquestion 1. in the typical active directory environment and doing wireless/wired 802.1x authentication on endpoints, should ACS join as a domain computer?
question 2. for the endpoint (domain computer) join the domain, in this case is the endpoint will trust the ACS ( also domain computer) ?
question 3. what if there's a GPO policy to install the rootCA certificate toward the endpoints. In this case, ACS should issue the CSR and let the domain CA to signed as the identity certificate? Am i correct?
I'm having some serious sound problem with some 2950 Cisco switches that I have in my CCNA lab these switches sound like a jet I've gone in and made sure the fans are clean and I even replaced one they still are too loud. So I have a few options I can run them without a fan which I really don't want to do but I want to look at two other options. The first option would be to put a heat sink on the chip that's producing heat I also thought about cutting a whole in the top and mounting a 120mm fan.

View 3 Replies View Relatedi have recently added to a domain. The initial setup is a server running windows 2003 and several xp machines which logon to the domain using mandatory profiles. However, after adding windows 7 machines and logging them on to the system it doesnt load the profiles. (which is fine as I understand you cannot use the same profiles with windows 7+xp)The problem is it automatically creates a roaming profile when logging off and saves it back to the same path as the other profiles under user.V2 which is growing considerably and causing huge logoff and logon times.How can I get the windows 7 machines to not attempt roaming profiles back to the server and instead to just save the profiles locally when logging off.

View 3 Replies View RelatedNeed securing a wireless environment in a hotel? The SSID has to be broadcast of course but how can we protect guests from man in the middle attacks, etc.? Currently the environment is all AP1200s with no hardware upgrades in the near future. There is also a 2811 router in place but nothing else. We would love to be able to force users to authenticate with a password in order to get out to the Internet as well.
View 2 Replies View RelatedI was asked to mount ACESMs on each of the CAT6K switches of a VSS cluster (one ACESM on each individual switch).On a non-VSS environment, the "svclc module <slot> vlan-group <group>" command is used to bind the VLAN group to the module on a certain slot. But now I am facing a VSS scenario, I will need to combine switch and slot in order to reference each of the individual modules...
How do I "index" each of the ACESMs in a VSS cluster? ¿Is there an extension of the aforementioned command to be able to combine switch and slot information?
I am looking to slowly migrate some of our wireless devices (Aironet 1231 and 1232's) to the Wireless N spec - 1260's.I currently have four AP locations that I want to upgrade first before anywhere else. At the minute, these four AP's work on the 2.4Ghz G band.
how the new 1260's will work in the mixed environment. I believe I will need to purchase the 1262 (which is the dual band version) so that I can operate the AP in both the 2.4Ghz G band range and the 5Ghz N range at the same time, is this correct?If I was to purchase the 1261 (which is the single band version), will I only be able to operate in either th 2.4Ghz or 5Ghz, but not at the same time?
For the mixed environment, would you suggest the dual band version? Can I place the same SSID on multiple Radios if this is the case? Following example: Say I have the SSID called 'Company' - this at the minute is operating on the G band 2.4Ghz range. If I was to purcahse the dual band 1262, could I put this SSID on both the G radio and the N radio? Would clients with an N adapter automatically connect to the 5Ghz range (N Radio) and legacy G and B adapters automatically connect to the 2.4Ghz (G Radio)?
We have the following BYOD environment:
WLC 5508 (7.4.100.0)Cisco Identity Services EngineVersion : 1.1.2.145 Patch Version : 3
During BOYD implementation we faced some problems with Android devices:
1) The Netwrok Setup Assistant (NSA) download process corrupts during the self-provisioning process (captured on 4.1.1 and 4.2.2 version)
2) If NSA is already installed, the network setup process (downloading profile, certificate) stops at last step: connecting to network, meanwhile the connection itself successfully establishes. This bug is captured on 4.2.2 version, 4.1.1 is ok.
Google ACL is configured according to TrustSec docs and permits all traffic to google networks 173.194.0.0/16 and 74.125.0.0/16.
I have decided build an open source firewall in linux environment. I have exactly one year to complete this project. The firewall will be a stateful packet filtering firewall working at network, transport and application layers. I would also be provided log analysis features.

View 13 Replies View RelatedIhave a 3560 w/multicast support and I'm trying to configure a simple environment. I have 2 ports configured, one for the multicast server and the other for the client. Each are on their own subnet, so I have an ip route between the two. My run config on both ports is:
ip multicast-routing distributed
interface fastethernet 0/3 & 0/4
ip pim version 2
ip pim sparse-dense-mode
I'm using vlc server /client configured to use 224.0.0.1 on my isolated network. I can see the mulitcast traffic going into the port, and I the client is sending reports, but I think the 3560 is dropping the packets, since I don't see them coming in the client port. Need to configure a simple multicast environment using 2 ports on a Cisco 3560.
I can't find any information that the AP1231G-A-K9 AP is supported in a 5508 Controller Based environment with Prime NCS.Could one of the experts confirm or deny?
