LAP removes client connections
Hello! We have WLC 5508 (6.0.188.0), and convert some APs-AIR-AP1141N-E-K9. Everything works well except one moment:
1 of this convert APs is located outside the office building, but it is always connected to our LAN as if he was in the office (there is a channel of fiber between our cisco switch and a switch, which is connected only 1 TURN)
The problem is that users can have the normal wi - fi on it beyond LAP. I see a few pings for the customer "associated" then drops, even a small success, that long drops.

What could be? Is it possible that some noise or anything that might bring him? The building with this problematic TURN is a kind of movie studio...
Well as long as the connection between the distance and the location to which is connected the wlc is good, then it can be achieved. If you click on the access point in the wireless tab wlc on the bottom of the picture you can see the availability and time of the join. If these hours are correct and not short, then the link is correct. Have you tried to exchange an ap to see if you still have the same problem and I'm guessing that customers in the main building of work very well, but when they go to the other site, they have some questions on the same SSID. If you think that it is reached, you can use a Spectrum Analyzer to determine which. Maybe some of the lighting or various wireless devices they could use there.

HP T510 - remove DESKTOP connections the connection with the HP Device Manager Manager remotely
I can manage, deploy, and send registry updated successfully to all HP T510 customers on my network via HPDM.
When deploying a RDP connection is successful, but it added the new connection in the connection list.
I was assuming that other connections would be withdrawn when the deployment of a record of a customer with the correct setting - but the new connection is just added to the existing list of RDP connections and I need to delete the other.
Please could someone advise me how to remove DESKTOP connections remote connection using HPDM Manager screen.
I found it! the option delete isn't available when deploying new connections - it's a checkbox at the bottom of the wizard

How can I remove a connection from network Local to my computer?
I have a connection to local network on my computer (XP Service Pack 3 operating system). I had this connection turned off for awhile and I also removed the ICON on the desktop for this connection. For many months, I noticed in the Log Viewer/system event I had a DCOM error every morning when I started my computer. Sometimes, the computer may pause for a few seconds, the screen would go black, and the system should restart automatically--normally. I would check the log Event Viewer/system and the DCOM error was there. At other times, the system should boot normally until he got to the window where I select user or administrator - at this time there, the mouse would be frozen in its tracks. A restart (by cutting the power supply to the computer) would all walk normally again. Another check of the event log and the DCOM error occurred once more here. I have to admit that the problems I identified here are rare visitors to my computer (no more than once or twice a week), but they are of course annoying. So, I believe that this connection to the unused LAN is at the root of my problem. Then I decided to activate the LAN connection, restart my computer and see if the DCOM error occurred when starting - no error has been found. Has it done for me, I decided that the unused LAN connection must go. I, however, have not found the magical instructions for how to remove the connection to the local network. I read an article that told me the Device Manager where it should be delete this connection. So I made a visit to the Device Manager and found the connection LAN listed there - I'm not sure this is the right thing to do. I also made a visit to the network connections and clicked on the unwanted local network connection - I found that delete is dimmed. I just seem to be lost as to how to make this connection to the local network to go. Can someone give me help in this task? Any help sent my way would be greatly appreciated.
It is a sequel to my last post. I decided, after that no response was forthcoming to this message, follow the instructions that I have included in this post more soon to try to remove the connection to the local network unwanted from my computer. FYI, this set of instructions worked perfectly and I have over this connection to the LAN on my system. I hope that this information will be useful to others you want to remove a local network of their Windows XP Pro SP3 system connection.

E3000 removes all connections every 2-6 hours
Every few hours the router removes all connections, wireless and wireline, and then they return to the minute. I thought initially the router itself was restart due to overheating, but solve any chance who did not stop the problem. I tried a lot of things, but I really have no idea what could cause a problem like that. Any ideas would be very useful because I'm quite confused.
Open the router configuration page and reduce the MTU to 1400 and click on save settings... Cycle power to the router and check.

Limits of pix 506 for VPN client connections
Hello. My company is looking to move away from using Microsoft's RRAS to workers to remote VPN connections. We have a 506th Pix currently serving 2 site VPN connections and client connections. Nobody knows what the limit for concurrent client vpn connections on a 506e and if having 10 to 20 clients connected at the same time (on a user base of 100 +) would cause problems. Any thoughts would be greatly appreciated.
There is no license for the number of connections limit, this is more a limitation of resources. Check that the data sheet a 506E can handle 16 MB of 3DES VPN. It's marketing plug so the actual throughput will be lower.
Hope that helps.

PIX: Cisco VPN Client connects but no routing
Hello
We have a Cisco PIX 515 with software 7.1 (2). He accepts Cisco VPN Client connections with no problems, but no routing does to internal networks directly connected to the PIX. For example, my PC is affected by the IP 172.16.2.57 and then ping does not respond to internal Windows server 172.16.0.12 or trying to RDP. The most irritating thing is that these attempts are recorded in the system log, but always ended with "SYN timeout", as follows:
2009-01-06 23:23:01 Local4.Info 217.15.42.214% 302013-6-PIX: built 3315917 for incoming TCP connections (172.16.2.57/1283) outside:172.16.2.57/1283 inside: ALAI2 / 3389 (ALAI2/3389)

We tried to activate and deactivate "nat-control", "permit same-security-traffic inter-interface" and "permit same-security-traffic intra-interface", but the results are the same: the VPN connection is successfully established, but remote clients cannot reach the internal servers.
I enclose the training concerned in order to understand the problem:

I join all the details of the cryptographic algorithms because the VPN is successfully completed, as I said at the beginning. In addition, routing tables are irrelevant in my opinion, because the inaccessible hosts are directly connected to the internal LAN of the PIX 515.

How can I control the number of clients connecting to one or more access points?
Hi guys,.
I am using several access points LWAPP/CAPWAP (1010, 1131, 1142) connected to the 4400 series wlan controllers (OS Version 4.2 and 7.0).
Regarding the client connection to access points, I have several questions:
1. extent to which clients can connect to an access point (maximum possible vs recommended)?
2. can I limit the maximum number of clients connecting to the access point in the gui controller? I found how to configure thresholds for sending traps when a number of clients connected to an access point is reached.
3 How can I balance the number of customers between two adjacent ap, who use the same SSID?
Best regards
Thorsten

867 EasyVPN server: Intermittent client connectivity
I have a rather peculiar question with a particular router, which I use as an EasyVPN server.
Customers have no problem to connect to the router. The Cisco VPN Client connects without problems and without fail every time.
HOWEVER
This does not mean that the customer can obtain from the server, which is located behind the router, to which they connect.
They might be able to. They might not! It seems to vary randomly. Sometimes the client will connect, and the server will be accessible. Othertimes, the client will connect and it will not.
Now, to do some very preliminary tests, I am STILL able to ping the router LAN interface once the tunnel is up. However, I may or may not be able to ping the server.
Yesterday, for example, the connection came. I was able to ping an IP address on the local network of 192.168.0.9. The router is 192.168.0.15, I have, as mentioned above, ping without problem as well. However, the server, which is 192.168.0.1, was not accessible. After a couple disconnects / reconnect to the VPN client, I could ping 192.168.0.1 (and 192.168.0.15) and if I could get on the server without problem... However, I could no longer ping 192.168.0.9.
It almost feels "subnetty", but there is nothing defined on the router that should cause this problem I can say. Clients receive an IP address in the range of 10.10.10.5 to 10.10.10.15 on a looping with IP 10.10.10.1.
Specific no reason why the pool overlaps the closure? being a virtual interface should not make a difference on where the traffic is sent, the EFC plays sometimes strange games.
If it's not too much to ask, you can disable this loopack?

Lenovo Ideapad S510 guard remove WIFI connections.
My Lenovo Ideapad S510 guard remove WIFI connections. When he falls, I have to unplug the router WIFI off and turn it on to get connectivity. Help appreciated - thanks
Hello
Please contact the Microsoft community.
I understand that your Lenovo idea S510 controller keeps on WIFI connections a fall during the use of the Internet.
I recommend you to check with the router manufacturer support you mentioned that issue gets fixed when you unplug the router.
You may encounter network or problems of Internet in Windows for several reasons. Some common problems that can cause these problems are:
Corrupt or incompatible drivers.
Network connection settings.
Hardware or software problems.
There is interference with other devices.
Your router and your PC network card can not work together.
I suggest you follow the below troubleshooting methods and check if it solves the problem.
Method 1: Run the network adapter Troubleshooter
If you cannot connect to a network, it could be a problem with your network adapter, the piece of hardware that allows your PC to connect to a network.
First of all, try to use the network adapter troubleshooting utility to automatically find and fix some problems. This troubleshooting will be disable and re-enable the adapter and try a few other common repairs. Here's how:
1. open the Control Panel by right-clicking on the Start button.
2 in the search box, type Troubleshooting, and then click Troubleshooting.
3 click network and Internet, run the utility network adapter troubleshooting, and follow the instructions
on your screen and check.
Method 2: Uninstall the network adapter driver and restart
Try to uninstall the network adapter driver, and then restart your computer and have Windows automatically installs the latest driver. Here's how:
1. right-click on Start, select Device Manager and navigate to the network cards > network adapter
name.
2 right click (or press and hold) the network card, and then select Uninstall > remove the driver
software for this device box > OK to confirm that you want to uninstall.
3 after uninstalling the driver, click on the Start button > power > restart.
After restarting your PC, Windows will automatically search for and install the network adapter driver. Check to see if this solves your connection problem.
If she does not then install download / install the driver from the websites of the manufacturers of Lenovo.
I hope this helps. If the issue is not resolved, please get back to us and we would be happy to help you.

ORA-12518: TNS:listener could not hand off client connection

Yesterday, I installed Oracle 12 c (12.1.0) and created ORCL12C (CBD) and a PDBORCL (PDB). I connected to the PDBORCL as SYS and created user 'SCOTT '.
I am able to connect to ORCL12C (PEH) without any problem (SQL * more and TOAD). I can go to PDBORCL (alter session set container = pdborcl) without problem. But I get the error above (ora-12518 am) when I try to connect to the user 'SCOTT' created in 'PDBORCL' using SQL * more or TOAD. I want to connect to the user SCOTT and create objects in schema SCOTT, etc.. I get the same error, even if I try to connect to the PDB as user SYS (alter session command works fine).
I am new to 12 C. So it is quite possible that I'm doing something fundamentally wrong.
