Connection Loss since 10.4.3 upgrade?

Our school just recently upgraded to 10.4.3 on our Emacs and Imacs. Previously when running 10.4.2 and ARD 2.2, I had NO connection problems. Now, I'm dropping connections to the students workstations just monitoring them. If I try to move any open folders on their desktops it drops and restores the connection? We have moved my station back to 10.4.2 with ARD 2.2, but the students are still 10.4.3 and they are still dropping. Anyone else having this problem? Anyone find a fix, without rolling all the Mac back to 10.4.2?

Some guesswork:
Do you have "Stealth Mode" enabled in System Preferences > Sharing > Firewall?
What are your Energy Saver settings on both machines?

Windows server 2012 and windows xp remote desktop connection loss

I am having this problem for a month now, and i am stumped with trying to find an answer . I have talked with several network admins in my area and with no luck i have not found a solution. I have a windows server 2012 placed with 5 pcs that are connected
on a local network , those 5 pc's connect to the server via remote desktop. List of pc's:
1x Windows 7
4x Windows XP SP3
All have the latests network drivers, all have the latest version of remote desktop installed. All have been scanned for viruses. All have antivirus software.
Problem is the 4 XP machines lose connection on when connected via remote desktop. If one starts losing connection the other 3 start to lose the connection aswell. The windows 7 machine is not affected by this it works fine.
What have I tried:
Scanning for viruses.
Disabling Firewall and antivirus software.
Updating all drivers.
Did many changes to group policy like keepalives etc.
Turning off SMBv2 SMBv3.
Turning off network adapter Offload settings.
Changed some registry settings like keepalive, smb etc.
Updating every pc and server with all windows updates.
Changed the router and switch.
Port forwarded needed ports like 3389.
Updating remote desktop to 7.0.
I might be forgetting some stuff i will add as i remember anything.
So the thing is this. I use a Windows XP machine from my office I remotely connect to the server via the Internet and I DO NOT experience any connection loss. BUT the XP machines on the local network constantly experience connection loss via remote desktop.
I pinged every Machine from the server via CMD command PING. So when they lose connection the Packets get time outs . Packets get dropped between 1-10 packets when a connection is lost. This packet drop does not occur when using the internet or anything else.
ONLY when connected to the server via remote desktop. The packets get dropped at random intervals.
Problem is I use an XP machine and I am not experiencing any loss of connection , while the XP machines on the local network experience it , but not the windows 7 machine.
Router is ASUS RT-N53 , and switch is Dlink DES-1008D. Server is a Dell PowerEdge T110 II.
Can someone please tell me what can i do to solve this problem?

So today got some word from their office. They were using RDP from 8AM until 12PM all was working fine. Then got back after lunch about 1PM and got a few connection lost errors when they tried using RDP again. Its weird since they didn't have disconnects
in the morning, and started having them after lunch.
Also noticed, that two pc were not using RDP and were disconnected as shown in task manager. And they still got request timeouts.
Maybe this is not a remote desktop issue?

Connection loss SUM GUI to SL Controller

Hi experts,
I am experiencing an issue that I need to resolve. It is that I lose the connection from SUM GUI (locally) to the SL Controller running on the remote server.
Currently I am doing an upgrade and after some time, e.g. when I have an error and don't notice it immediately, I get a warning message.
"The connection to the SL Controller is down.
The SDT GUI will reestablish the connection, when possible."
On the server I get the following error message:
May 26, 2014 7:49:47 AM [Error]: com.sap.sdt.engine.core.communication.FactoryAlreadyRegisteredException: Factory for key 'com.sap.sdt.engine.core.com

My current assumption is that the firewall drops the connection due to inactivity.
The main issue then is:
although I restart my local SUM GUI and reconnect to the server I can't continue the upgrade because the Buttons are "unclickable" (grey).
Currently I always had to restart SUM including the services on ther server (SL controller).
My question is:
what can I do to avoid this connection loss?
Is there a option to set a "keep alive" to the network connection?
so that the firewall does not validate the connection as idle and drops?
Unfortunately we can't do much about the firewall settings due to security restrictions.
I would be glad to hear from you.
Kind regards,
Niklas

Hi Mathias,
I got an answer from SAP. There is no option that can be executed with STARTUP to solve this.
I already proposed to forward this request to the dev team at SAP
What I am currently doing is:
Start the GUI and keep it open only if I know if there is are Actions coming next, otherwise I close it (only the GUI) and when some time has passed by I logon again to check.
This is a really bad solution, but currently the only one.
Regards,
Niklas

Why do I have Intermittent Wifi Connection Loss during music streaming ?

Hello,
I have an ipad3 and an iPhone 4S and I am getting with both devices interruption of the sound when I send music to the Apple TV. It generally happens after a few minutes. The signal for the wifi is still good and I have still access to the Internet I have tried all the recommendations of the article "iOS: Troubleshooting Wi-Fi networks and connections" but this did not help. I have used several applications for sending music to the Apple TV (music application from Apple and DSAudio from Synology) but I'm getting the same issue. I have also the same issue with the media center application from Bouygues Telecom connecting directly to my internet router. My router is a bbox sensation. I had also the same kind of issue with my old router when sensing photo albums to the internet: I had the error message "your system is running low on ressources". How can I solve these intermittent wifi connection losses ?

Try #5.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Since my IPOD Touch upgraded to IOS 8.1.2 it will not play well with my 2013 Charger's UConnect entertainment system. It will not build a library so I can not Browse or Shuffle. The only thing Is there a fix for UConnect issue?

Since my IPOD Touch upgraded to IOS 8.1.2 it will not play well with my 2013 Charger's UConnect entertainment system. It will not build a library so I can not Browse or Shuffle. The only thing it does is list all the songs alphabetically when connected via USB.

- Contact the manufacturer/go to their support site.
- Sometimes this works
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
To delete all music go to Settings>General>Usage>Storage>Music>Tap edit in upper right and then tap the minus sign by All Music
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.
Sometimes and ISO update breaks compatibioity and a firmware update the the dock is required or an iOS update is required.
Downgrading the iOS is not supported by Apple.

My camera connection kit stopped working after I upgraded to ios5

My camera connection kit stopped working after I upgraded to ios5. If I plug it in to my iphone I get a message saying it is not recognised, but when I plug it into the ipad it does nothing at all. I've tried resetting it, but that makes no difference.
I have an ipad 1 which I bought because it had lots of storage. I'm going on holiday soon, and I want to be able to upload my holiday photos to my ipad while I'm away.
Any suggestions?

Actually this sounds the same problem I have on my iPad2.
I use a cheap copy of the CCK which I got off eBay.
It worked great when fitted with a 16gb SD card, but since I upgraded to 5.01 it has stopped working.
Sorry, no solution at this point but it worked on 4.3.3 but not on 5.01.
I'll keep on looking, was considering a proper CCK thinking the cheapmversion may be drawing too much current, but it sounds like that might not work either.

Firewire problem since 10.4.6 upgrade

The package i upgraded with was about 45 mb i see there is a 10.4.6 upgrade combo at about 140 mb when i get to a high speed computer connection i'm goin to try that with the drives unhooked. i've already tried this with the 45 mb one and nothing also reset pmu

Since iOS 5.0 upgrade, can't add details into calender. Any ideas

Update! I took some general advice on the forum and rebooted my iPhone a few times. I also asked the phone to "forget this device" and attempted to reconnect several times. It would load my contacts and then proceed to disconnect from the phone and I would also see a message on the Bluetooth page that the BlueAnt ST3 was not supported.
I gave up.
I left the two devices plugged into my computer for power overnight, laying side by side on the table.
They found each other. The next day they connected and have been communicating ever since.
Perhaps until the next IOS upgrade? But a happy ending in the interim

HPC8180 Printer wont connect to wireless network, after firmware upgrade to Wireless Router

My HPC8180 has been connecting wirelessly since I bought it sometime ago. I recently had to upgrade the firmware on my Netcom NB9W wireless router and since then my HP wont resolve to the wireless network.
I run the Wireless Network wizzard on the printer, select the correct SSID and enter the WEP key as per instructions.
It then will not connect.
The summary I print out says it passes everything except:
No Filtering = Fail
Connected = Not Run
Signal Strength = Very Low (which is strange because it's about 10ft from Wireless Router).
Other networks detected matching your network name (SSID) = No
Summary says:
Network Name (SSID) altnet (correct)
IP Address = Not applicable
Configuration Source = Not applicable
Communication Mode = Infrastructure
Authentication Type = Open System
Encryption = 64-bit WEP
I have NOT turned on mac address filtering
Any ideas??
This question was solved.
View Solution.

Your router appears to be a DSL modem router. Those can be tricky to connect to. Also, WEP can be problematic and is no longer a good security measure. WEP can be broken in about 10 minutes with freeware from the internet.
Let's do three things:
1. Change to WPA or WPA2 encryption. You can make up your own password. Make it 13 or more characters, numbers and letters, upper and lower case.
2. Reset the Network Defaults in your printer (Setup > Network area).
3. Attach to the router in this way:
Sometimes DSL providers have more control over the router than the printer likes.
- Unplug the telephone line from the router
- Turn the power off on the router, wait 30 seconds, then turn the power back on.
- Go through the normal process of connecting the printer to the device (Wireless Setup WIzard)
- Now find the IP address of the printer (it should be on the self-test printout), type it into a browser.
- On that screen you will find a Networking Tab, then on the left Wireless, then the IPv4 Tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you know what that is, set an IP outside that range but no higher than 254 (the last number in the address).
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Leave the gateway and DNS blank
- Finally, plug in the phone line, reboot the router and test.

My apple tv intermittently stops playing music while playing Songza. network connection is strong. i have upgraded to the latest appletv s/w
what can i do to fix this?

Strangely enough, I exchanged the ATV2 and ATV3 and now both work fine. I suspect it may have something to do with the fact that (previously) the ATV3 (1080p) was behind an ethernet hub. Somehow the ATV2 (720p) does not mind being behind the hub. Either that or iTunes suddenly became smarter since the exchange . Anyway, it works now so I'm not touching it. Thanks for the suggestion.

IPad 2 WiFi Connection Loss After Update To iOS 4.3.2

I've been watching with growing alarm the explosion of complaints of iPad 2 WiFi connectivity issues since the upgrade to iOS 4.3.2. My iPad is becoming almost unusable because of this issue, and this after flawless performance of the two iPad 2 32GB WiFi-only machines I bought 15 March 2011. All the suggested solutions I've read of do not solve the problem.
This is very disturbing, and I hope Apple addresses this soon.

I also left feed back. I thought apple was also on this did not realize it was just user to user with change. Thanks Carolyn!

Since the last 3 upgrades (thru Firefox 7.0) I can't print a web page. This is true using 2 different printers. I have an iMac 10.6.8.

Just read that the default memory storage on FF is set to 5 mbs. You can up that by clicking on tools, advanced and overriding the default and set it to 50 mbs (if you use lots of tabs) or 10 mbs (if you use just a few).
I open a blank tab and clear the cache periodically, while I am working. I can have several tabs open and watch videos on Youtube, by doing this. Have you cleared your cache?
Since I have an older computer, I've also used CCleaner for years. I use it often, but always before signing off. You can get it free...search for CCleaner, download from Pirifoam free. I didn't change any of the settings and it clears crap left behind from uninstalling programs, clears all browsers at once of: cookies, history, passwords, etc. I love it!
I had freezing, before using the "open blank tab, clear the cache" thing. Now I have no problems. Plus, as I said...you can change the default memory usage for FF and that should help too.
Hope this helps! Good luck! :)

HT1199 I-pod no longer reconised by computer since downloaging the latest upgrade from i-tunes?

Ipod no longer reconised by computer since downloading the lastest upgrade from i tunes.

Same here.
I have tried all the repeated reccomendations I've found in other posts.
Nothing has worked.
I have tried installing older versions of ITunes also...will not recognize my library so it will not start up. Have tried rebuilding it. Not working....
One thing that did work was resetting my Ipod nano...now all I have is the message "Please use Itunes to sync music to this Ipod." :/

Xperia T- Bluetooth Issues since Andriod 4.3 Upgrade.

Hello All.
Since my phone was upgraded to Andriod 4.3 Jelly bean, I've been unable to make calls from my phone via my BMW car audio as before, as the Bluetooth link keeps dropping out.
I've tried re- pairing the phone to my car, but this has made no difference.
The Bluetooth seems to work ok with other devices.
Questions are:
1) Does anyone know what the problem is and how to fix it.
2) If not, is it possible to re- install the previous version of Bluetooth that came with Android 4.1 Jelly Bean and worked perfectly ok with the car audio.
3) As a last resort, is it possible to install a 3rd party Bluetooth App to try and resolve the problem.
Hope somebody out there can help !

I Have an Xperia Z and once again since the update battery drains superquick, the phone gets hot and the bluetooth is all but useless, I work for a motor dealer, since this update I cannot pair my phone to most of our vehicles to demonstrate the system (and yes it did pair fine to these cars and vans prior to update), I get the message Bluetooth share has stopped or it will re-boot the entire phone, I did have a conversation with Sony who deemed that I should back up and restore the handset, which once done may or may not work (it didn't) and they seem to be completely denying a problem, which as I have checked various forums there very clearly is a major issue

Why are the calendars on my Mac no longer syncing with my iPhone and/or my iPad since the last IOS upgrade?

Since installing the IOS upgrade, it seems impossible to sync the calendar(s) on my iMac (via the cloud OR via cable) with my iPhone 4 or my iPad (last generation).
Any thoughts?

What happens when you try to sync? Error messages?
